Who qualifies for Semaglutide

Our EU-licensed doctors review each case individually to determine if Semaglutide is a safe and appropriate treatment for you. Generally, doctors look for patients with 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 high blood pressure or type 2 diabetes. Contraindications include a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), and severe allergic reactions to Semaglutide. During your consultation, ensure you provide a complete medical history for the doctor to assess your eligibility thoroughly.

What Semaglutide actually does (and doesn't do)

Semaglutide is a GLP-1 receptor agonist. It mimics a natural hormone that targets areas of the brain involved in appetite regulation. This helps you feel fuller, reduces hunger, and can lead to eating less. It also slows down digestion and can improve blood sugar control. While Semaglutide is an effective tool for weight management, it is not a magic bullet. It works best when combined with lifestyle changes, including a reduced-calorie diet and increased physical activity. Significant weight loss typically occurs over several months, not weeks. Doctors often start with a low dose, gradually increasing it to minimise side effects and help your body adjust.

Side effects and when to stop

Like all medications, Semaglutide can cause side effects. The most common ones are mild and temporary, including nausea, vomiting, diarrhea, or constipation. These often subside as your body adjusts to the medication. To manage them, doctors recommend starting with a low dose, gradually increasing it, eating smaller meals, and avoiding very fatty foods. Less common but more serious side effects include pancreatitis, gallbladder problems, kidney problems, and severe allergic reactions. If you experience severe abdominal pain, persistent vomiting, yellowing of the skin or eyes (jaundice), or significant changes in urination, contact a doctor immediately. Your EU-licensed doctor will discuss these risks with you and monitor your progress through your private, RGPD-compliant chat in the Hi-Doctor app.
