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, which slows how quickly the stomach empties and reduces 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 constant willpower.
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 the 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 are 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 is the best way to find the treatment that suits you.

Most people see steady weight loss over the first year, with results continuing while they remain on treatment alongside diet and activity changes.

- Switching from Mounjaro to Wegovy also needs a one-week gap; your prescriber advises the starting dose
