Semaglutide

Semaglutide (Ozempic/Wegovy)

Also known as: Ozempic, Wegovy, GLP-1

Overview

A GLP-1 receptor agonist originally developed for type 2 diabetes that has become the leading FDA-approved medication for chronic weight management. Semaglutide mimics the incretin hormone GLP-1, reducing appetite, slowing gastric emptying, and improving glycemic control.

Half-Life
~7 days
Typical Dose
0.25–2.4 mg
Frequency
Once weekly
Cycle Length
Ongoing / indefinite under medical supervision

  • Diarrhea or constipation
  • Abdominal pain and bloating
  • Risk of pancreatitis (rare)

Mechanism of Action

  • Activates GLP-1 receptors in the hypothalamus to reduce appetite
  • Delays gastric emptying to promote satiety
  • Enhances glucose-dependent insulin secretion from pancreatic beta cells
  • Suppresses glucagon release to improve blood sugar regulation

Research Summary

The STEP clinical trial program demonstrated that semaglutide 2.4 mg weekly produces an average weight loss of approximately 15% of body weight over 68 weeks. The SELECT trial further showed a 20% reduction in major adverse cardiovascular events. FDA-approved for chronic weight management in adults with BMI ≥30 or ≥27 with at least one weight-related comorbidity.
