Semaglutide
The GLP-1 agonist that brought incretin-based weight management into the mainstream, with established roles in diabetes and obesity medicine.
What It Is
Semaglutide is a long-acting GLP-1 receptor agonist. Different formulations and brands are approved for type 2 diabetes and chronic weight management, and specific labeling includes cardiovascular-risk reduction in defined populations.
The Effects That Made GLP-1s Famous
Reduced hunger and increased satiety are among the most noticeable effects.

Strong humanThe Reference Point For The Category
For the general public, semaglutide effectively became synonymous with “GLP-1.” It is the molecule that made terms like food noise, appetite signaling and incretin therapy part of everyday conversation, and it remains the baseline against which many newer obesity drugs are compared.
GLP-1 Receptor Agonism
Semaglutide mimics GLP-1 activity, increasing glucose-dependent insulin secretion, reducing glucagon under hyperglycemic conditions, slowing gastric emptying and signaling satiety in the central nervous system.
Deep Human Evidence Base
Semaglutide has extensive randomized-trial evidence across type 2 diabetes, obesity and cardiovascular outcomes. In the STEP 1 obesity trial, participants receiving 2.4 mg weekly lost about 14.9% of body weight on average at 68 weeks versus 2.4% with placebo.
Known Class Effects
Gastrointestinal adverse effects are common. Current labeling also contains warnings and contraindications specific to GLP-1 therapy and to the individual semaglutide product.
Product-Specific Dosing
Semaglutide dosing depends on the product and indication. Injectable products use gradual dose escalation; oral semaglutide has different administration requirements. Current FDA labeling should be used for exact approved schedules.
