Who qualifies for Semaglutide

Our EU-licensed doctors carefully assess your eligibility for Semaglutide. They look for specific criteria, typically requiring a Body Mass Index (BMI) of 30 or higher, or a BMI of 27 or higher with at least one weight-related comorbidity (such as type 2 diabetes, high blood pressure, or high cholesterol). They also consider your medical history to ensure there are no contraindications. Conditions like a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) are usually contraindications. Your doctor will ensure Semaglutide is safe and appropriate for your specific health profile.

What Semaglutide actually does (and doesn't do)

Semaglutide is a GLP-1 receptor agonist. It mimics a natural hormone in your body that targets areas of the brain involved in appetite regulation. This leads to reduced hunger, increased feelings of fullness, and a slower emptying of the stomach. The result? You naturally eat less and feel satisfied longer. It's important to understand that Semaglutide is a tool to support weight loss, not a magic bullet. It works best when combined with healthy lifestyle changes. Realistic timelines show that significant weight loss is gradual, typically over several months, not weeks. It doesn't guarantee instant results, nor does it replace the need for a balanced diet and regular physical activity.

Side effects and when to stop

Like all medications, Semaglutide can have side effects. The most common are mild to moderate gastrointestinal issues such as nausea, vomiting, diarrhoea, or constipation, especially when you first start treatment or increase your dose. These often improve over time. Our doctors will guide you on managing these. Less common but more serious side effects can include pancreatitis or gallbladder problems. You should stop Semaglutide and seek immediate medical attention if you experience severe abdominal pain, persistent vomiting, or symptoms of an allergic reaction. Your doctor will discuss all potential side effects and red flags during your consultation and monitor your progress.
