Semaglutide is a GLP-1 receptor agonist — an FDA-approved medication originally developed for type 2 diabetes and later approved, under a different brand and dosing, for chronic weight management in certain adults. Like other GLP-1 medications, it works by mimicking a natural gut hormone that influences appetite and how full you feel.
What the evidence shows
In clinical trials, semaglutide helped many participants lose a meaningful percentage of body weight when combined with lifestyle changes. Individual results vary widely, and the medication is not appropriate for everyone.
The honest trade-offs
Common side effects include nausea and digestive discomfort, especially early on. There are important contraindications your provider will screen for. Weight often returns if medication stops without lasting habit changes — which is why provider supervision matters.
Who decides
A licensed provider — never a website — determines whether semaglutide or another GLP-1 is clinically appropriate for you, based on your history and current FDA guidance. A prescription is never guaranteed.
