- Constant hunger or emotional eating patterns
- Difficulty losing weight with diet alone
- Repeated cycles of weight loss and regain
- People preferring a non-surgical medical approach
- Patients who want structured doctor follow-up

How Wegovy works
Semaglutide is a long-acting version of GLP-1, a hormone the gut releases after meals. It acts on appetite centres in the brain so you feel full sooner and think about food less, and it slows stomach emptying. Because it lasts about a week in the body, a single weekly injection is enough.
The dose is started low and stepped up gradually as prescribed, giving the digestive system time to adjust. Clinical trials reported meaningful average weight loss when semaglutide was used with diet and activity; individual results vary. Weight may return after stopping without lasting habit changes, so the doctor discusses maintenance from the start. See our weight loss injections guide for how it compares with other options.
