In short: Wegovy (semaglutide) is a once-weekly injection in doses from 0.25 mg to 7.2 mg. At Able Clinic the 0.25 mg starter dose costs £69 a month and the 2.4 mg maintenance dose costs £139 a month. Average weight loss was about 15% at 68 weeks in the STEP 1 trial.
How Wegovy works
GLP-1 is the hormone your gut releases after eating to tell your brain you are full. Semaglutide mimics GLP-1 and lasts a whole week per injection.
Appetite drops, portions shrink, and the background hum of cravings fades. In the SELECT trial, semaglutide also reduced the risk of major cardiovascular events by 20% in people with existing heart disease.
Prefer not to inject? The Wegovy pill delivers the same medicine as a daily tablet.
