What happens if you stop taking Wegovy?

Stopping Wegovy often leads to a return of appetite and gradual weight regain after treatment ends, as the semaglutide-driven appetite suppression and satiety effects wear off. Blood sugar control may worsen once GLP-1 activity returns to baseline, potentially causing higher glucose levels than during treatment. Some of the cardiovascular protections seen with semaglutide – such as reduced risk of heart attack or stroke – may also diminish after stopping, increasing overall cardiovascular risk. There are no true withdrawal symptoms, but rebound effects typically occur over about 5–7 weeks as the drug clears from the body. Working with your clinician to taper doses gradually and maintain diet and exercise habits can help minimise weight regain and metabolic changes.

• Appetite usually returns to pre-treatment levels once Wegovy is stopped, driving increased food intake.
• Most people regain a significant portion of lost weight, often two-thirds within a year of discontinuation.
• Blood sugar levels can rise after stopping, as the GLP-1–mediated insulin and glucagon effects subside.
• Cardiovascular benefits decline after discontinuation, potentially raising overall cardiovascular risk.
• Wegovy leaves the system over 5–7 weeks, with rebound effects peaking as drug levels fall.
• Gradual tapering under medical supervision and sustained lifestyle measures help reduce weight regain and metabolic rebound.
