About Wegovy
What is Wegovy and how does it work?
Wegovy is a prescription-only medicine containing semaglutide, a GLP-1 receptor agonist. It mimics a hormone released after eating, slowing how quickly the stomach empties and reducing appetite signals in the brain.
How it works
Semaglutide acts on GLP-1 receptors to reduce hunger and food noise, making it easier to eat less without relying on willpower alone.
How effective is it?
In clinical studies, adults lost an average of 20.7% of body weight over 72 weeks when they stayed on treatment alongside diet and activity changes.
How long until results?
Most people notice reduced appetite within the first weeks. Weight change builds gradually as your dose is stepped up.

Understanding side effects
Most side effects are digestive and appear early in treatment or after a dose increase. For most people they’re mild to moderate and settle as the body adjusts.
Digestive side effects
Nausea, diarrhoea, vomiting, constipation, indigestion and burping are the most common effects, usually strongest in the first weeks and after each dose increase.
Other common side effects
Headache, dizziness, fatigue, injection-site reactions and temporary hair thinning linked to rapid weight loss.
Dehydration
Persistent nausea, vomiting or diarrhoea can lead to dehydration. Sip fluids regularly and tell your prescriber if symptoms are severe or prolonged.
Less common but serious
Gallbladder problems, pancreatitis and severe allergic reactions are rare. Seek urgent help for severe abdominal pain with vomiting.
Eligibility
Wegovy supports weight management alongside healthy eating and regular physical activity. A thorough assessment finds the treatment that suits you.

Results
What weight loss with Wegovy can look like. Individual results vary.
What to expect over time
Most people see steady weight loss over the first year, with results continuing while they stay on treatment alongside diet and activity changes.
Clinical trial data
- STEP 1: 14.9% average loss at 2.4mg over 68 weeks
- STEP UP: 20.7% average loss at 7.2mg over 72 weeks

Head-to-head data
In SURMOUNT-5, semaglutide delivered 13.7% mean weight loss compared with 20.2% for tirzepatide over 72 weeks.
Body composition
Most of the weight lost comes from fat mass, but keeping muscle through regular activity and enough protein matters throughout treatment.
