Introduction
Nexplanon is a type of birth control that many people choose because it is long-lasting, effective, and easy to use. It is a small, flexible rod placed under the skin of the upper arm by a healthcare provider. Once inserted, it releases a hormone called etonogestrel into the body. This hormone helps prevent pregnancy by stopping the release of eggs from the ovaries, thickening the mucus in the cervix to block sperm, and thinning the lining of the uterus so it is less likely to support a pregnancy. Nexplanon can work for up to three years, making it a convenient option for those who want long-term contraception without daily pills or frequent visits to the clinic.
While Nexplanon is known for being safe and reliable, some people notice changes in their bodies after getting the implant. One of the most common concerns is weight gain. Many users report gaining weight while using Nexplanon, and this side effect has led to confusion and concern. Questions like “Does Nexplanon make people gain weight?” and “How much weight is normal to gain?” are often searched online. Others want to know if the weight gain will go away after removal or if there is anything that can be done to prevent it.
Understanding whether Nexplanon causes weight gain is not simple. Weight can change for many reasons, and hormones are only one part of the picture. Some people gain weight while using the implant, while others do not notice any change. There are even cases where people lose weight while using Nexplanon. This shows that weight gain is not guaranteed and may depend on a person’s individual body, lifestyle, and other health factors.
Medical studies have looked at the link between Nexplanon and weight gain, but the results have not always been the same. Some studies report that the average weight gain is small and not very different from weight changes seen in people who are not using hormonal birth control. Other research shows that a group of users may experience more noticeable weight gain, especially if they already have certain risk factors such as a higher body mass index (BMI) or a history of gaining weight on other types of birth control.
There is also confusion about what type of weight gain happens with Nexplanon. Some users report feeling bloated or swollen, which may be due to fluid retention rather than fat gain. Others may notice increased hunger, changes in how the body stores fat, or differences in metabolism. These effects are often connected to how the hormone in Nexplanon affects the body, including hunger signals and how food is processed for energy.
The idea that Nexplanon might cause weight gain leads many people to wonder what can be done. It is helpful to look at the science and the patterns seen in studies. It is also important to think about lifestyle choices like diet, exercise, and sleep, which can all play a role in weight changes. In some cases, people might think about removing the implant if the weight gain feels too difficult to manage, but this decision should be made carefully and with medical advice.
This article will explore the most common questions about Nexplanon and weight gain. It will explain what is known from science, what causes might be behind the weight changes, and what can be done to reduce or manage weight gain. The goal is to give clear and helpful information so that people using Nexplanon—or thinking about it—can feel more confident and prepared.
What Is Nexplanon and How Does It Work?
Nexplanon is a type of birth control that comes in the form of a small, flexible rod. It is about the size of a matchstick and is placed under the skin of the upper arm by a healthcare provider. Nexplanon is known as a long-acting reversible contraceptive, or LARC. This means it works for a long time but can be removed at any time if pregnancy is desired.
Nexplanon contains a hormone called etonogestrel, which is a type of synthetic progestin. Progestins are man-made forms of a natural hormone in the body called progesterone. Etonogestrel is slowly released from the rod into the bloodstream over time. Once it is in the body, the hormone helps prevent pregnancy in three main ways.
It Stops Ovulation
The most important way Nexplanon prevents pregnancy is by stopping ovulation. Ovulation is the process where an egg is released from an ovary each month. Without an egg, sperm cannot fertilize anything, so pregnancy cannot happen. Etonogestrel works by sending signals to the brain to stop the release of hormones that trigger ovulation. As a result, most people using Nexplanon do not ovulate.
It Thickens Cervical Mucus
Nexplanon also makes the mucus in the cervix thicker. The cervix is the opening to the uterus. When mucus becomes thick and sticky, it becomes harder for sperm to pass through and reach the egg. This makes it less likely for fertilization to happen.
It Thins the Lining of the Uterus
A third way Nexplanon prevents pregnancy is by thinning the lining of the uterus, also called the endometrium. The lining is where a fertilized egg would normally attach and grow during pregnancy. A thinner lining makes it harder for an egg to implant, even if fertilization happens. This further lowers the chance of pregnancy.
How Long Nexplanon Works
Nexplanon is approved to work for up to three years, but some studies suggest it may still prevent pregnancy for up to five years. Most people choose to have it removed and replaced after three years to stay within the official guidelines. When removed, fertility usually returns quickly. Most people are able to become pregnant soon after the rod is taken out.
How Nexplanon Is Inserted and Removed
The implant must be placed by a trained healthcare provider. The area on the inside of the upper arm is cleaned, and a small amount of local anesthetic is used to numb the skin. The provider then uses a special applicator to insert the rod just under the skin. The whole process takes only a few minutes. A bandage is applied afterward, and there may be some soreness, bruising, or swelling for a few days.
Removing Nexplanon is also done in a clinic or medical office. A small cut is made to pull out the rod. Removal usually takes a few minutes, though it can take longer if the implant has moved. After removal, another can be inserted right away if continued contraception is desired.
Effectiveness of Nexplanon
Nexplanon is one of the most effective types of birth control. It is more than 99% effective at preventing pregnancy. This means fewer than 1 out of 100 people using it will get pregnant in a year. Unlike birth control pills, there is no need to remember to take something every day. Because it works automatically once inserted, the chance of user error is very low.
Nexplanon is a small rod that releases the hormone etonogestrel to prevent pregnancy. It works by stopping ovulation, thickening cervical mucus, and thinning the uterine lining. It lasts for up to three years and is over 99% effective. Because it is long-lasting and easy to use, many people choose it as a reliable birth control method.
Can Nexplanon Cause Weight Gain?
Many people worry about gaining weight after starting Nexplanon, the small implant placed in the upper arm to prevent pregnancy. This concern is common and understandable, especially when making choices about long-term birth control. While some people do report weight gain during Nexplanon use, the science behind this issue is not simple. Studies have found different results, and not everyone experiences the same side effects.
What Research Says About Weight Gain and Nexplanon
Nexplanon contains a hormone called etonogestrel. This hormone is a type of progestin, which helps stop the body from releasing eggs during the monthly cycle. It also thickens the mucus in the cervix to keep sperm from reaching an egg and makes the lining of the uterus thinner so that a fertilized egg is less likely to attach. These changes help prevent pregnancy, but they may also affect other parts of the body.
During clinical trials, some users of Nexplanon reported weight gain. However, the average amount of weight gained was small. According to the manufacturer’s data, about 13% of users stopped using Nexplanon early because of weight gain. On average, those who stayed on the implant for three years gained around 2.8 pounds. This amount is not very different from the average weight gain seen in adults over three years without any birth control use, which is often due to aging, lifestyle, or other factors.
Other studies have shown mixed results. Some studies find no clear link between Nexplanon and weight gain, while others suggest that certain people may be more sensitive to hormone-related weight changes. Overall, the available research shows that some people might gain weight on Nexplanon, but many others do not.
Possible Reasons for Weight Gain on Nexplanon
If weight gain does happen, several possible causes may be involved. These causes can work alone or together, making it hard to know if the implant is the main reason.
- Changes in Appetite:
Hormones can affect how hungry or full the body feels. Progestin may lead to changes in the levels of hunger hormones like ghrelin and leptin. Ghrelin tells the body it’s time to eat, while leptin tells it to stop. When hormone levels shift, hunger cues may become stronger or harder to control. Some people may feel hungrier more often or find it harder to feel full after meals, leading to extra calories and weight gain over time.
- Slower Metabolism:
Some researchers believe that progestin may slightly reduce how fast the body burns calories at rest. A slower metabolism means the body uses less energy, even while doing the same activities. If eating habits stay the same but the body burns fewer calories, extra weight may build up slowly.
- Water Retention:
Another reason for early weight gain may be fluid retention. Hormonal changes can cause the body to hold onto water, making a person feel bloated or heavier. This is not the same as fat gain, and it may go away on its own after a few weeks or months.
- Lifestyle Changes:
Starting a new birth control method may happen at a time when other life changes are taking place. For example, changes in diet, exercise, stress, or sleep habits can all affect weight. If these changes happen around the same time as starting Nexplanon, it may seem like the implant is the reason, even if it is not the only cause.
Medical experts agree that Nexplanon does not directly cause major weight gain for most people. The body’s response to hormones is different for each person. Some may notice a few pounds of weight gain, while others may lose weight or stay the same. The average amount of weight change is small and often similar to what might happen naturally over time.
Because the reasons for weight gain are often complex, it is not easy to say that Nexplanon always causes it. It may play a role, but diet, exercise, genetics, and other health factors are just as important. For those who notice weight changes, it can help to keep a record of eating habits, physical activity, and how weight changes over time. Talking with a healthcare provider can also help rule out other causes and make a plan if weight gain becomes a concern.
Why Do Some People Gain Weight on Nexplanon?
Not everyone who uses Nexplanon gains weight, but for those who do, it can be frustrating and confusing. Understanding why this happens can help make it easier to manage. Several reasons may explain why some people gain weight while using Nexplanon. These include how the body reacts to hormones, changes in appetite, fluid retention, fat storage, and lifestyle habits.
Hormonal Sensitivity and Individual Differences
Nexplanon contains a hormone called etonogestrel. This is a type of progestin, which is a man-made hormone similar to the natural hormone progesterone. Some bodies react more strongly to this hormone than others. The way the body responds depends on many factors, like genetics, metabolism, and overall hormone balance.
For example, one person’s body may keep its regular weight, while another may gain weight because their metabolism slows down or their appetite increases. Hormones play a big role in controlling hunger, how the body uses energy, and where fat is stored. These reactions are not the same for everyone.
Increase in Appetite
One of the most common changes seen in people using Nexplanon is an increase in appetite. Hormones like progestin can affect hunger signals in the brain. The hormone ghrelin, often called the “hunger hormone,” may become more active. This makes the body feel hungry more often, even if it doesn’t need more food.
At the same time, the hormone leptin, which helps the body feel full, may not work as well. When hunger increases but the feeling of fullness doesn’t keep up, it becomes easy to eat more than usual without noticing. Over time, eating extra calories can lead to weight gain.
Changes in Metabolism and Fat Storage
Hormones also affect how the body uses and stores energy. When metabolism slows down, the body burns fewer calories, even when doing the same activities as before. If food intake stays the same or increases, the unused calories can be stored as fat.
Progestin may also affect where the body stores fat. Some people notice more fat around the stomach, hips, or thighs. These changes are related to hormone levels, and while they are not dangerous, they can feel uncomfortable or unwanted.
Water Retention vs. Fat Gain
Sometimes what feels like weight gain is actually fluid buildup. Hormonal changes can cause the body to hold onto more water than usual. This is called water retention. It can make the body feel bloated or swollen, especially in the hands, feet, and stomach.
Water weight can come and go, and it is different from gaining fat. While it can affect how clothes fit or how the body feels, it usually does not mean long-term weight gain. Drinking more water, reducing salt intake, and staying active can help reduce water retention.
Lifestyle Habits and Emotional Changes
In some cases, the weight gain is not caused by Nexplanon alone. Life changes after starting birth control may also play a role. For example, someone might stop exercising as often, change eating habits, or feel more tired or stressed. These changes can lead to weight gain over time.
Hormonal birth control may also affect mood. Some people feel more anxious, sad, or less motivated. These feelings can lead to emotional eating or less physical activity. When these patterns continue, they can contribute to gaining weight.
There is no single reason why some people gain weight on Nexplanon. It can be a mix of hormonal effects, increased appetite, slower metabolism, water retention, and lifestyle changes. Each person’s body reacts in its own way. While the implant is a safe and effective birth control method, understanding how it might affect weight can help in making healthy choices and knowing when to talk to a doctor.
Is the Weight Gain from Nexplanon Permanent?
Some people notice weight gain after getting the Nexplanon birth control implant. This can cause concern, especially if the weight does not seem to go away quickly. However, in many cases, the weight gain is not permanent.
Temporary vs Long-Term Weight Changes
Weight gain while using Nexplanon can be temporary. This means it may happen for a short time and then stop or even go away. Some people notice they gain a few pounds in the first few months. This can be due to changes in hormone levels caused by the implant. The body may respond to the hormone by holding on to water or by increasing appetite. These changes do not always last. For many people, weight levels out after the body adjusts to the hormone.
Long-term weight gain means the body keeps gaining weight over time or does not lose the extra weight while still using the implant. Some users may keep the added weight as long as the implant stays in place. But even in these cases, the weight gain is often not extreme.
What Happens After Nexplanon Is Removed?
Once the Nexplanon implant is removed, hormone levels in the body go back to normal over time. This may help the body release extra water or reduce appetite. For some people, this means they lose some of the weight they gained during use. Others may find that their weight stays the same after removal unless they make changes to diet and exercise habits.
In studies where weight was tracked before and after Nexplanon use, many participants returned to their previous weight within several months of having the implant taken out. However, each person’s body responds differently. Not everyone will lose weight after removal, especially if weight gain was due to other factors like lifestyle or medical conditions.
How Hormones Affect Weight Over Time
Nexplanon contains a hormone called etonogestrel. This hormone is a form of progestin, which can cause changes in the body. In some people, it may increase hunger. Others may notice they feel more tired or have lower energy levels. These changes can lead to eating more or moving less, both of which can affect body weight.
Over time, the body may adjust to the hormone, and the effects may become weaker. This means that weight gain may slow down or stop without any major changes in lifestyle. But in other people, the hormone’s effects may stay strong for the full three years the implant is in place.
Research on Weight Reversibility
Several studies have looked at whether weight gain from hormonal birth control like Nexplanon goes away after stopping use. In most of these studies, a portion of users did return to their starting weight after removal. Other studies show mixed results, with some people keeping a few extra pounds even after stopping. The outcome often depends on how much weight was gained, how long the implant was used, and what lifestyle habits were in place.
People who gained a small amount of weight—such as 3 to 5 pounds—were more likely to lose it after Nexplanon was removed. Those who gained more, or who had other risk factors for weight gain like poor diet or low physical activity, were less likely to return to their original weight without making healthy changes.
Weight gain on Nexplanon is not always permanent. In many cases, the weight is mild, short-term, and may go away once the body adjusts or after the implant is removed. For some people, weight gain lasts longer, especially if it is related to lifestyle or other health issues. Making healthy choices such as eating well and staying active can help manage weight while using Nexplanon or after it is removed. If weight gain becomes a concern, talking to a healthcare provider is the best way to understand what might be causing it and what can be done about it.
How Much Weight Gain Is Considered Normal or Concerning?
Weight gain while using Nexplanon is a common concern. Some people may notice changes in their weight after getting the implant, while others may not see any difference at all. Understanding how much weight gain is typical and when it may become a concern can help people know what to expect and when to seek help.
What Is Normal Weight Gain?
Many people experience small changes in weight over time, even without using hormonal birth control. A small gain of 1 to 5 pounds over a few months is often considered normal. This may happen due to water retention, changes in appetite, or even natural shifts in body weight.
Clinical studies on Nexplanon have shown that most users do not gain a large amount of weight. According to data from the manufacturer and clinical trials, the average weight gain over one year was around 2 to 4 pounds. Some people gained more, while others lost weight or stayed the same. These numbers show that small weight changes are common and usually not a cause for concern.
Weight gain that happens slowly and levels off is often harmless. The body may adjust to the new hormone levels, and weight may stabilize after the first few months. Gaining a few pounds over the course of a year is often not directly harmful if overall health stays good.
When Is Weight Gain a Concern?
Some people may notice a sudden or large increase in weight, such as gaining more than 10 pounds in a short period of time. This may be a sign that the body is reacting strongly to the hormone in Nexplanon. Although it is less common, this kind of rapid weight gain should not be ignored.
Weight gain becomes more concerning if it continues steadily over time, does not slow down, or leads to other health issues. For example, if someone gains 15 to 20 pounds in a year and also begins to feel tired, has trouble sleeping, or notices changes in mood or energy, it may point to other problems. In these cases, it is important to talk to a healthcare provider.
What Causes the Weight Gain?
Not all weight gain on Nexplanon comes from fat. Sometimes, it is caused by water being stored in the body (water retention), especially in the first few weeks. This kind of gain often causes bloating and may go away on its own.
In other cases, the hormone in Nexplanon may affect appetite. Some people feel hungrier or eat more often without realizing it. If more calories are taken in than the body uses, the extra energy is stored as fat. This can lead to weight gain over time.
Lack of exercise, stress, changes in sleep, or eating habits may also play a role. For example, if someone becomes less active or starts eating high-calorie foods while using Nexplanon, the weight gain may not be caused by the implant itself. It may be the result of lifestyle changes.
Keeping Track of Weight
Paying attention to body weight over time can help spot any unusual changes. Writing down weight, food habits, and activity levels once a week may show if there is a pattern. If weight gain happens quickly or does not stop, it may be easier to find the cause.
Small weight changes of 1 to 5 pounds over several months are usually not a reason to stop using Nexplanon. These can often be managed with healthy eating and regular physical activity. However, if weight gain feels out of control or affects daily life, medical advice may be needed.
When to Seek Help
Healthcare providers can help figure out if the weight gain is related to Nexplanon or another cause. They may check for health conditions like thyroid problems, insulin resistance, or depression, which can also lead to weight gain. In some cases, a dietitian or weight management specialist may help with setting healthy goals.
Understanding what amount of weight gain is expected—and when to ask for help—can make using Nexplanon feel more manageable. Most people who gain weight while using the implant see only small changes. With healthy habits and regular check-ups, it is possible to keep weight under control while continuing to use effective birth control.
Are There Certain Risk Factors That Increase the Likelihood of Gaining Weight on Nexplanon?
Weight gain with Nexplanon does not happen to everyone, but some people may be more likely to experience it than others. Several risk factors can make weight gain more likely while using the implant. These include a person’s starting weight, family health history, hormone levels, medical conditions, and daily habits such as diet and exercise. Understanding these risk factors can help people and their healthcare providers make more informed choices about managing side effects.
Starting Body Mass Index (BMI)
A person’s body mass index, or BMI, is a number that compares weight to height. It is often used to group people into weight categories such as underweight, normal weight, overweight, or obese. Some studies have shown that people who already have a higher BMI before getting Nexplanon may be more likely to gain weight while using it.
This does not mean that everyone with a higher BMI will gain weight. However, hormone changes may affect people differently depending on their body type. For example, people with more body fat may already have higher levels of estrogen or insulin in the body. Adding a new hormone, like the progestin in Nexplanon, may interact with those existing hormone levels and lead to more noticeable weight changes.
Family History of Obesity or Weight Struggles
Genetics can also play a role in how the body responds to weight changes. People who have close family members—such as parents or siblings—who struggle with obesity or weight gain may be more likely to have similar experiences. This may be due to inherited traits, shared eating patterns, or how the body stores fat and burns energy.
When Nexplanon changes the hormone balance in the body, it may trigger appetite changes or slow down the metabolism in people who already have a higher genetic risk. Even small changes in eating habits or physical activity may lead to weight gain more easily in these cases.
Hormonal Conditions Like PCOS or Insulin Resistance
Some people already have hormone-related conditions before using Nexplanon. Polycystic ovary syndrome (PCOS) is a common condition that affects how the ovaries work. People with PCOS often have high levels of androgens (male-type hormones), irregular periods, and difficulty with weight control. Another related issue is insulin resistance, which means the body has trouble using insulin properly. This can raise blood sugar levels and lead to fat storage.
When someone with PCOS or insulin resistance uses a hormonal birth control method like Nexplanon, the extra progestin may make it harder to manage weight. The implant can also cause the body to hold onto more water or increase hunger signals. As a result, people with these conditions may be more likely to see weight changes compared to others.
Low Physical Activity and Unbalanced Diet
Daily habits play a major role in how the body manages weight, whether or not a person uses birth control. If someone does not get regular physical activity or eats a diet high in processed foods, sugars, or fats, they may be more likely to gain weight over time. Nexplanon may add to this by increasing appetite or changing how the body stores fat.
It is also common for people to notice changes in mood, energy, or stress levels after starting birth control. These changes can affect how often a person exercises or what types of food they eat. For example, stress can lead to overeating or cravings for comfort foods. Feeling tired or sluggish may also lead to less movement during the day, which reduces the number of calories burned.
Stress and Sleep Patterns
Stress and sleep are often overlooked but important factors in weight control. High stress levels can raise cortisol, a hormone that tells the body to store fat—especially around the stomach area. People who are stressed may also find it harder to stick to healthy eating or exercise routines.
Poor sleep habits can have similar effects. Not getting enough sleep can make the body feel hungrier during the day and reduce the energy needed for exercise. Nexplanon may slightly affect mood or sleep in some users, which can indirectly increase the chance of weight gain if not managed.
Several factors can raise the risk of gaining weight while using Nexplanon. These include having a higher BMI before starting the implant, a family history of weight issues, hormone conditions like PCOS, and lifestyle patterns such as poor diet, low exercise, stress, and sleep problems. While these risk factors do not guarantee weight gain, they can make it more likely. Recognizing these influences early may help people take steps to maintain a healthy weight while using Nexplanon.
How to Tell if Nexplanon Is Causing Weight Gain
Weight gain is a common health concern, and many people who use Nexplanon wonder if the implant is the cause. Hormonal birth control can affect the body in different ways, and not all weight changes are caused by it. Understanding how to tell if Nexplanon might be linked to weight gain can help guide the next steps.
Timing of Weight Gain
One of the first things to look at is the timeline. If weight gain started shortly after getting the implant, this may suggest a possible link. Many people begin to notice changes in weight within the first few months after insertion. This may include a slow but steady increase, or in some cases, a more rapid change.
However, weight can change for many reasons. It is important to look at when the weight gain started. If there were no other major changes in diet, activity, or stress levels, then Nexplanon may be a factor. But if weight gain began much later—several months or even a year after insertion—other causes might be involved.
Ruling Out Other Causes
Weight gain can be caused by many different things, including:
- Changes in eating habits or calorie intake
- Decreased physical activity
- Increased stress or emotional eating
- Lack of sleep
- Medical conditions like thyroid disorders or polycystic ovary syndrome (PCOS)
- Certain medications, such as antidepressants or steroids
Before assuming Nexplanon is the cause, it is helpful to consider these other possibilities. Sometimes, people may gain weight due to life changes—starting school, changing jobs, or dealing with stress—that happen around the same time as starting Nexplanon. These changes can affect sleep, appetite, and activity levels.
Medical conditions that affect hormones, like underactive thyroid or insulin resistance, can also cause weight gain. A healthcare provider may suggest blood tests to rule out these problems.
Using a Symptom and Weight Log
Tracking weight and symptoms over time can provide helpful information. A weight log can be as simple as writing down weight once a week. It can also include notes about eating habits, physical activity, mood, and energy levels. This helps create a full picture of what might be happening in the body.
Using a symptom diary to track things like hunger, bloating, cravings, sleep quality, and mood changes can also give clues. For example, if there is a noticeable increase in appetite or strong cravings that began after getting Nexplanon, this might suggest a connection.
Looking back at these records over a few weeks or months can help identify patterns. If weight changes match the timing of starting the implant and other causes are unlikely, then Nexplanon may be contributing.
Talking to a Healthcare Provider
If weight gain continues or becomes hard to manage, it is important to speak with a doctor or nurse. Bringing a weight and symptom log to the appointment can help the provider understand what is going on. The provider may ask questions such as:
- When did the weight gain start?
- Have there been changes in diet or activity?
- Are there any new symptoms like fatigue or changes in mood?
- Are other medications being taken?
A provider may check for medical causes of weight gain through lab tests or physical exams. If no other cause is found and Nexplanon appears to be the most likely factor, a plan can be made. This might include lifestyle changes, follow-up monitoring, or in some cases, discussing whether to continue with the implant.
Telling whether Nexplanon is causing weight gain takes careful observation and sometimes help from a healthcare provider. Looking at when the weight gain began, ruling out other causes, and keeping track of changes can make the picture clearer. Weight gain is not the same for everyone, and finding the cause is the first step in managing it effectively.
What Can You Do to Prevent or Manage Weight Gain While Using Nexplanon?
Some people notice weight gain after getting the Nexplanon implant. While not everyone gains weight, those who do may feel frustrated or confused. The good news is that there are ways to help prevent or manage weight gain while still using Nexplanon. These steps focus on healthy habits, simple changes, and support from health professionals when needed.
Healthy Eating Habits
Food choices play a major role in body weight. After starting Nexplanon, some people may feel hungrier or may eat more often. Paying attention to eating habits can help manage this change.
- Eat balanced meals: Each meal should include a mix of vegetables, fruits, protein, and whole grains. This helps the body feel full and get the nutrients it needs.
- Watch portion sizes: Even healthy foods can lead to weight gain if eaten in large amounts. Using smaller plates or measuring portions can help.
- Limit high-calorie snacks and drinks: Sodas, juices, chips, and sweets are high in calories but do not fill the body up for long. Replacing them with water, fruits, nuts, or yogurt can help reduce extra calories.
- Plan meals and snacks: Preparing meals ahead of time makes it easier to eat healthy foods and avoid last-minute fast food or unhealthy snacks.
- Eat mindfully: Eating slowly and without distractions like TV or phones helps the brain notice when the stomach is full.
Regular Physical Activity
Exercise helps burn calories and keeps the body strong. It can also help reduce stress and improve mood, which may help avoid emotional eating.
- Start with small steps: Walking, biking, or stretching for just 20–30 minutes a day can make a difference. Over time, more movement can be added.
- Find fun ways to move: Dancing, playing sports, swimming, or even gardening are good ways to stay active.
- Stay consistent: Aim for at least 150 minutes of moderate activity per week, as recommended by health experts. This can be broken into shorter sessions across several days.
- Use daily habits: Taking the stairs, walking during breaks, or parking farther away can help increase daily movement without needing extra time.
Managing Stress and Sleep
Hormones from stress and poor sleep can make it harder to manage weight. They may also increase appetite and cause cravings for unhealthy food.
- Get enough sleep: Most teens and adults need between 7 and 9 hours of sleep each night. A regular sleep schedule helps the body stay balanced.
- Create a calming routine: A quiet bedtime routine, such as reading or taking a warm bath, can help improve sleep quality.
- Practice stress-relief techniques: Deep breathing, journaling, or spending time outside can reduce stress. Yoga or meditation may also help.
Keeping Track of Changes
Writing down meals, exercise, weight, and mood can help spot patterns. For example, if hunger increases after starting Nexplanon, tracking it can show if it continues or levels off. Using a journal or an app makes it easier to stay on track and notice what works.
When to Seek Help
If weight keeps increasing despite healthy habits, a visit to a doctor or dietitian may help. A healthcare provider can:
- Check for other medical causes, like thyroid issues or hormone imbalances
- Give advice on nutrition, activity, and managing appetite
- Recommend support programs for weight management
Some people may benefit from talking with a registered dietitian. These professionals help create a personalized eating plan that fits individual needs, culture, and preferences.
Staying Positive
Making changes takes time, and progress may be slow. Small steps, taken regularly, can lead to better long-term results. Focus on health rather than just numbers on a scale. Feeling more energetic, sleeping better, and having fewer cravings are all signs of improvement—even if weight loss is small at first.
Healthy habits can help reduce or prevent weight gain while using Nexplanon. These habits also improve overall well-being, whether or not weight changes happen. With the right support, many people find that they can manage their weight and still use Nexplanon safely and effectively.
Should You Remove Nexplanon If You’re Gaining Weight?
Weight gain can be frustrating and concerning. When it happens after getting a birth control implant like Nexplanon, some may wonder if the implant is the cause. Others may think about having it removed. Deciding whether to remove Nexplanon because of weight gain depends on several important factors.
Consider the Timing of the Weight Gain
One of the first things to think about is when the weight gain started. If it began shortly after Nexplanon was inserted and no other changes were made to diet, exercise, or lifestyle, it may be connected to the implant. However, weight can also change for many other reasons. These include stress, changes in routine, certain medications, health conditions, or even lack of sleep. Hormonal birth control may play a role in weight gain for some people, but it is usually only one part of a bigger picture.
Understand That Not Everyone Gains Weight on Nexplanon
Most clinical studies have found that the average weight gain on Nexplanon is small. Some people gain a few pounds, while others may not see any change at all. A smaller group may gain more weight. Everyone’s body reacts differently to hormones, and this is why it’s hard to predict how someone will respond. Because of this, some people may choose to wait a few months to see if their weight levels off before deciding to remove the implant.
Explore Other Possible Causes of Weight Gain
Before deciding to remove Nexplanon, it is helpful to check for other possible reasons for the weight gain. For example, if someone has been more stressed, is getting less physical activity, or has changed eating habits, those things could explain the change in weight. Health issues such as thyroid problems or polycystic ovary syndrome (PCOS) can also affect weight. Sometimes lab tests may be needed to rule out other causes. Talking with a healthcare provider can help make sure no other health problems are being missed.
Try Lifestyle Changes First
Before making the choice to remove Nexplanon, doctors usually recommend trying a few lifestyle changes. Even small steps can make a difference. This might include planning healthy meals, limiting sugary snacks or drinks, and getting regular physical activity. Exercise does not have to be intense; even walking for 30 minutes a day can help. Managing stress, sleeping well, and drinking enough water are also important. Tracking meals and activity in a journal or app can help spot habits that might be causing weight gain.
If these changes help stop the weight gain or lead to weight loss, there may be no need to remove Nexplanon. But if the weight continues to rise despite healthy habits, it might be time to talk with a provider again.
Talk to a Healthcare Provider Before Removal
Removing Nexplanon is a medical decision that should be made with help from a healthcare provider. It is important to talk openly about weight concerns, changes in appetite, and anything else that feels different since getting the implant. The provider may ask questions, check for other causes, and give advice on the next best step. If it seems that Nexplanon is likely the main reason for the weight gain, then removal can be discussed.
Healthcare providers will also want to make sure there is a safe plan for birth control after removal, especially for those who are not ready to become pregnant. Other birth control methods may be better suited for people who are sensitive to hormones.
Weigh the Pros and Cons
Nexplanon is a very effective form of birth control. It lasts up to three years and does not require daily attention like pills. Removing it means giving up that protection, so it’s important to think carefully. If the weight gain is mild and manageable, it may be worth keeping the implant. But if the gain is large, affecting self-esteem, or causing health concerns, removal could be the right option.
The final choice should balance the benefits of pregnancy prevention with how the body is reacting. Each person’s health, goals, and comfort level matter. A good decision is one that takes both physical and emotional well-being into account.
How Does Nexplanon Compare to Other Birth Control Methods in Terms of Weight Gain?
Many people wonder if Nexplanon causes more weight gain than other birth control options. Some may feel frustrated if they notice weight changes after starting Nexplanon and want to know if switching to another method would help. To answer this, it helps to look at how different types of birth control work and what research says about weight gain with each one.
Hormonal vs. Non-Hormonal Birth Control
Birth control methods can be divided into two main groups: hormonal and non-hormonal. Hormonal methods contain hormones that prevent pregnancy. These hormones can sometimes affect appetite, water balance, or fat storage. Non-hormonal methods do not affect hormone levels, so they are less likely to cause weight changes.
Hormonal methods include:
- Birth control pills (oral contraceptives)
- The patch
- The ring
- Depo-Provera (the shot)
- Hormonal IUDs (like Mirena, Liletta)
- Nexplanon (the implant)
Non-hormonal methods include:
- Copper IUD (like Paragard)
- Condoms
- Diaphragms
- Natural family planning
Among hormonal methods, the type of hormone and how it is delivered can make a difference in how the body responds.
Nexplanon Compared to Other Progestin-Only Methods
Nexplanon is a progestin-only birth control. It contains etonogestrel, a form of synthetic progesterone. It does not contain estrogen.
Another common progestin-only method is Depo-Provera, the birth control shot. Studies have shown that Depo-Provera has the highest risk of weight gain among hormonal methods. Some people gain 5 to 10 pounds within the first year of using the shot, and for some, the weight gain continues over time. The shot may also increase fat mass, especially in younger users.
Nexplanon does not appear to cause as much weight gain as Depo-Provera. In clinical trials, the average weight gain with Nexplanon was about 2 to 4 pounds over three years. Some people gained more, and some lost weight. Overall, the weight change was small, and most users did not report major issues. This suggests that while Nexplanon may cause weight gain in some people, it is less likely to cause significant weight gain than the shot.
Nexplanon Compared to Combination Birth Control (Estrogen + Progestin)
Combination birth control pills, the patch, and the vaginal ring all contain both estrogen and progestin. Many people worry that the estrogen in these methods causes weight gain, but studies show that most people do not gain a lot of weight from these methods.
Estrogen can sometimes cause fluid retention, which might make someone feel bloated or heavier at first. However, this effect is usually mild and temporary. In most studies, weight gain from combination methods was less than 5 pounds, and often similar to weight changes seen in people not using any birth control at all.
Compared to these methods, Nexplanon does not contain estrogen, so it does not usually cause water retention. But because it works over a long period and is placed in the body, some users may feel unsure if changes in weight are from the implant or from other factors like diet, stress, or age.
Nexplanon Compared to Hormonal IUDs
Hormonal IUDs like Mirena or Liletta also contain only progestin (usually levonorgestrel). These IUDs work mostly in the uterus and release very low levels of hormone into the bloodstream. Because of this, they tend to have fewer whole-body side effects.
Some people report weight gain with hormonal IUDs, but most studies show no strong link. The average weight change is very small, and some people even lose weight. Compared to these IUDs, Nexplanon may have a slightly higher risk of weight gain, possibly because it releases more hormone into the bloodstream.
What Research Suggests
Large reviews of birth control studies have found that most hormonal methods do not cause major weight gain. In fact, weight gain over time is common in all adults, whether or not they use birth control. Many factors can affect weight, including:
- Age and metabolism
- Stress and sleep
- Physical activity
- Diet
- Genetics
While some people gain weight on Nexplanon, many others do not. There is no clear evidence that Nexplanon causes more weight gain than other birth control methods, except possibly when compared to non-hormonal options or hormonal IUDs.
Nexplanon is a progestin-only birth control method that may cause mild weight gain in some users. Compared to Depo-Provera, it is less likely to cause significant weight gain. When compared to combination pills, the patch, or the ring, the difference in weight gain is small. Hormonal IUDs may have an even lower risk of weight-related side effects.
For those concerned about weight, it is helpful to talk to a healthcare provider. They can explain the options and help choose a method that fits individual health goals and needs.
When to Talk to a Healthcare Provider About Weight Gain on Nexplanon
Weight gain while using Nexplanon can be confusing and sometimes frustrating. Some people notice only a small change, while others may experience a more noticeable increase. It’s not always easy to know if the implant is the cause or if something else is going on. That’s why it’s important to understand when it’s a good idea to talk to a healthcare provider.
Unexplained or Rapid Weight Gain
If weight starts to increase quickly without a clear reason, this may be a sign to check in with a healthcare provider. For example, gaining five or more pounds in a short time—like within a few weeks—without any major changes in eating habits or physical activity can be a concern. Sudden weight gain could point to other health problems, such as fluid retention, changes in hormone levels, or an issue with metabolism.
Other Symptoms Along with Weight Gain
Weight gain that happens with other symptoms may also need medical attention. These symptoms might include:
- Feeling tired all the time
- Mood swings or depression
- Hair thinning or hair loss
- Acne getting worse
- Swelling in the hands, legs, or face
- Irregular periods after the first few months on Nexplanon
These signs could point to conditions like thyroid problems, polycystic ovary syndrome (PCOS), or even a reaction to the hormone in the implant. A healthcare provider can help sort out what’s normal and what needs testing.
Trouble Managing Weight Despite Efforts
If weight continues to increase even with healthy eating and regular physical activity, it may help to speak with a healthcare provider. Sometimes, hormonal birth control can change how the body stores fat or handles hunger. A provider can offer support, rule out other causes, and suggest strategies that match the person’s body type and lifestyle.
Mental or Emotional Stress About Weight
Concerns about body image and weight can lead to stress, anxiety, or even depression. Feeling upset or frustrated about body changes is not uncommon. If emotional health is being affected, it’s important to talk about it with a medical provider. Mental and physical health are closely linked, and both should be supported during any birth control use.
Preparing for a Medical Visit
Before the visit, it helps to gather some information. Keeping a daily log of weight, food intake, mood, sleep, and exercise can give useful details to the provider. Writing down when weight changes started and whether any other symptoms occurred can also help. The provider may ask questions like:
- When was Nexplanon inserted?
- When did the weight gain start?
- Has appetite changed?
- How often is physical activity done each week?
- Have there been any changes in periods, skin, or mood?
Answering these questions can guide the next steps in care.
What the Provider Might Do
The provider may check vital signs, perform a physical exam, or order tests. These may include:
- Thyroid blood tests
- Hormone levels
- Blood sugar or insulin levels
- A complete blood count
- Kidney or liver function tests
The goal is to find out if the weight gain is related to Nexplanon or something else. If it seems like the implant is likely causing unwanted changes, the provider may suggest a trial period with lifestyle changes or, in some cases, removing the implant.
Shared Decision-Making
It’s important to remember that birth control is a personal choice. A healthcare provider can help weigh the benefits and side effects of Nexplanon. This includes looking at how well it prevents pregnancy, how the body is responding, and what options might be better if side effects are not manageable. Decisions are made together, based on each person’s health needs and goals.
Talking to a healthcare provider early on can prevent bigger problems later. It can also bring peace of mind. Whether the next step is more testing, changing habits, or switching birth control, getting support from a medical expert can make the process easier and safer.
Conclusion
Nexplanon is a small, flexible implant placed under the skin of the upper arm. It releases a hormone called etonogestrel and is used as a long-acting birth control method. It is over 99% effective at preventing pregnancy and lasts for up to three years. Many people use Nexplanon because it is easy to use, does not require daily attention, and works well. However, one concern that comes up often is whether Nexplanon causes weight gain. This is a question many people search online, and it can lead to confusion, worry, or frustration.
Weight gain while using Nexplanon is possible, but it does not happen to everyone. Clinical studies and patient reports have shown that some people gain weight, while others stay the same or even lose weight. The average weight change is usually small, but it can feel more noticeable for some individuals. Research shows that the hormone in Nexplanon may affect appetite, how the body stores fat, and how much water the body holds. These changes can lead to an increase in body weight over time, especially during the first year of use.
It is also important to know that people’s bodies respond to hormones differently. Some are more sensitive to hormonal changes than others. Those who have a history of weight gain on other hormonal birth control methods, such as the shot or birth control pills, may also be more likely to gain weight on Nexplanon. Other risk factors include a higher body mass index (BMI) before starting the implant, a family history of obesity, poor diet, low levels of physical activity, or conditions like polycystic ovary syndrome (PCOS). Lifestyle habits also play a big role. Hormones might increase hunger for some people, and without changes in diet or exercise, weight gain can happen more easily.
While weight gain may occur, it is not always permanent. For many users, weight levels out after the first year or may return to normal after the implant is removed. The weight gain may also be temporary water retention rather than actual fat gain. Removing the implant is one option if weight gain becomes a serious concern, but this decision should be made carefully. A doctor can help decide whether Nexplanon is the main cause of weight gain or if something else may be involved. It is not always easy to know right away. Keeping track of weight changes, diet, mood, and activity levels can help doctors see patterns and give better advice.
There are many healthy ways to manage weight while using Nexplanon. Eating balanced meals, choosing fresh foods over processed ones, and staying active with regular exercise can all help. Sleep and stress management are also important, since both affect weight. Even small changes in routine can lead to steady progress over time. If weight continues to rise and it becomes difficult to manage, a dietitian or healthcare provider can give personalized support. They may suggest ways to adjust food intake or physical activity, or they might check for other health issues.
For those wondering if switching birth control might help, it is important to understand that no method is completely free from the chance of side effects. Some people gain weight on one type and not another. Hormonal methods, including pills, shots, and implants, all affect the body in different ways. Non-hormonal options such as the copper IUD usually do not cause weight gain, but they come with their own risks and benefits. Comparing methods with the help of a provider can give a better picture of what to expect and how to make the best choice.
In summary, weight gain on Nexplanon can happen, but it is not guaranteed and does not affect everyone the same way. Most cases involve small changes, and many people are able to manage their weight by focusing on healthy habits. If weight gain becomes a problem, it is helpful to speak with a doctor to explore the cause and possible solutions. Choosing the right birth control is a personal decision. It should be based on medical advice, personal health needs, and how the method fits into daily life. With the right support and information, it is possible to use Nexplanon effectively and feel confident in managing any changes that may occur.
