What is semaglutide?
Semaglutide is a medicine that mimics GLP-1, a natural gut hormone involved in appetite and blood-sugar control. It acts on the brain's appetite centres and slows stomach emptying, so many people feel less hungry and full sooner. For weight management it is prescribed as Wegovy, a pre-filled pen injected under the skin of the abdomen, thigh or upper arm once a week.
Treatment starts at a low dose that is increased step by step over several weeks, which helps the body adjust and reduces side effects. Semaglutide is not a quick fix: it works most effectively together with healthier eating and regular activity, and weight can return if the medicine is stopped without lasting lifestyle changes. At Egg Clinic a doctor decides whether it is appropriate for you and which dose to start.
Who is a good candidate for semaglutide?
- Adults with obesity, or overweight with weight-related health issues
- People who have struggled to lose weight with diet and exercise alone
- Patients who can attend follow-up or continue care at home
- Those willing to combine medication with lifestyle changes
Semaglutide is not suitable during pregnancy or breastfeeding, or if you or a close relative have had medullary thyroid cancer or MEN2 syndrome. People with a history of pancreatitis, certain gallbladder or kidney problems, or type 1 diabetes need special caution, and it is not used purely for small cosmetic weight changes. Please bring a list of your medications. For body shaping of specific areas the doctor may instead suggest fat loss injections.

What side effects can semaglutide cause?
The most common side effects are digestive: nausea, a feeling of fullness, constipation, diarrhoea or occasional vomiting, especially in the first weeks and after dose increases. They are usually mild to moderate and tend to ease over time. Eating smaller meals, stopping when full and drinking enough water can help. Rarer but serious effects include pancreatitis and gallbladder problems, so severe or persistent abdominal pain needs prompt medical attention. Your doctor will explain warning signs and how to adjust if side effects are troublesome.
