4. Pick up your Semaglutide at any EU pharmacy – from Spain to Germany.

Who qualifies for Semaglutide

When you consult with a Hi-Doctor EU-licensed physician, they assess your medical history and current health to determine if Semaglutide is right 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 type 2 diabetes, high blood pressure, or dyslipidemia. Certain contraindications, like a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2, will prevent a prescription. The doctor ensures your safety and suitability for this GLP-1 treatment.

What Semaglutide actually does (and doesn't do)

Semaglutide, a GLP-1 receptor agonist, mimics a natural hormone in your body that regulates appetite and blood sugar. It works by slowing down food movement through your stomach, making you feel fuller for longer. It also acts on your brain to reduce hunger and cravings, and helps your body release insulin more effectively. What it doesn't do is offer a quick fix; Semaglutide is a tool to support your weight management journey, not a magic bullet. Realistic results are achieved over time, combined with lifestyle changes.

Side effects and when to stop

Like any medication, Semaglutide has side effects. Most commonly, you might experience mild to moderate gastrointestinal issues such as nausea, vomiting, diarrhoea, or constipation, especially when you first start treatment or increase your dose. These usually improve as your body adjusts. However, be aware of red flags: severe abdominal pain, persistent vomiting, or yellowing of the skin or eyes. If you experience these, stop the medication and seek medical attention immediately. Your Hi-Doctor physician will guide you on managing common side effects and recognising when to stop.
