Mechanism of Action

How GLP-1 Agonists Work

GLP-1 agonists like Semaglutide and Wegovy® mimic the
natural hormone GLP-1. Here’s an expanded look at how they work:

1. Binding
   to GLP-1 Receptors: They bind to GLP-1 receptors in the pancreas,
   stimulating insulin secretion. This helps cells absorb glucose from the
   bloodstream, reducing blood sugar levels.
2. Suppressing
   Glucagon: They suppress glucagon release, reducing liver glucose
   production. This further helps control blood sugar levels.
3. Delaying
   Gastric Emptying: They slow down the stomach’s emptying process,
   leading to a feeling of fullness. This reduces food intake, aiding in
   weight loss.
4. Central
   Nervous System Effects: They may also act on the brain to reduce
   appetite. This central action complements the peripheral effects,
   providing a multifaceted approach to weight management.

This complex mechanism of action sets GLP-1 agonists apart
from other weight loss medications, offering a unique approach that targets
multiple aspects of metabolism and appetite regulation.

Combination Therapies

Integrating with Other Weight Loss Strategies

Combining Semaglutide or Wegovy® with other weight loss
strategies can enhance results:

• Diet
  and Exercise: A balanced diet and regular exercise are essential
  components of any weight loss plan. When combined with GLP-1 agonists,
  they can lead to more significant and sustainable weight loss.
• Behavioral
  Therapy: Cognitive-behavioral therapy can help address underlying
  eating habits and psychological factors that may contribute to weight
  gain. Integrating therapy with medication can enhance effectiveness and support
  long-term success.
• Other
  Medications: Some patients may benefit from combining GLP-1 agonists
  with other weight loss medications. This approach must be carefully
  managed by healthcare providers to ensure safety and effectiveness.

  Blood Sugar Control: Losing weight can improve insulin sensitivity,
  making it easier to control blood sugar levels. This can reduce the need
  for diabetes medications or even lead to remission in some cases.
• Cancer
  Risk Reduction: Weight loss may reduce the risk of obesity-related
  cancers, although more research is needed to fully understand this
  relationship.
• Enhanced
  Mental Well-being: Achieving and maintaining weight loss can improve
  self-esteem, reduce depression and anxiety, and enhance overall quality of
  life.
