You have probably heard the brand names. Behind them is a class of medications called GLP-1 receptor agonists, originally developed for type 2 diabetes and now widely used to support weight loss.

How they work

GLP-1 medications mimic a hormone your gut releases after eating. They slow how quickly your stomach empties and signal fullness to your brain, so you feel satisfied on less food.

Who they are for

These medications are prescribed alongside diet and lifestyle changes, typically for people with a higher BMI or weight-related health conditions. A licensed provider evaluates whether they are a safe fit for you.

What to expect

Results build gradually over months, not days. Mild nausea is the most common early side effect and usually fades. Ongoing physician support and lab monitoring help keep treatment safe and on track.
