Body Composition Analysis: Why It Matters Before Weight Loss Drugs

At Hi-Doctor, we make it simple, fast, and risk-free. For a flat fee of €25, an EU-licensed doctor reviews your case. If approved, you receive a REMPE electronic prescription in under 24 hours, valid at any pharmacy across the EU.

How it works — get your weight loss drug prescription in 4 steps

  2. A licensed EU doctor reviews your case in private. If the doctor decides the treatment is not appropriate, your €25 is refunded automatically — no risk.
  3. If approved, you receive a REMPE electronic prescription (PDF file) in your Hi-Doctor account and by email within 24 hours.
  4. Print the PDF or show it on your phone — present it at any pharmacy in the EU (e.g., Spain, Portugal, Italy, France, Germany, Netherlands, Belgium, Austria, Ireland) to collect the medication.

Who qualifies for weight loss drugs

Our EU-licensed doctors assess each patient individually to determine suitability for weight loss medications like GLP-1s (e.g., semaglutide, tirzepatide). Generally, doctors look for patients with a Body Mass Index (BMI) of 30 or higher (obesity), or a BMI of 27 or higher (overweight) with at least one weight-related comorbidity such as type 2 diabetes, high blood pressure, or high cholesterol. Contraindications, such as a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2, will also be carefully evaluated. The doctor ensures the medication is safe and appropriate for your specific health profile.

What weight loss drugs actually do (and doesn't do)

Medications like Wegovy (semaglutide) and Mounjaro (tirzepatide) are GLP-1 receptor agonists. They work by mimicking a natural hormone in your body that regulates appetite and blood sugar. This means you feel fuller faster, stay full longer, and experience reduced cravings. While these medications significantly aid weight loss, they are most effective when combined with lifestyle changes, including a balanced diet and regular physical activity. They are not a magic bullet; rather, they are a powerful tool to support your weight loss journey when deemed appropriate by a doctor. Realistic timelines for significant weight loss typically span several months, with consistent use and adherence to a healthy lifestyle.

Side effects and when to stop

Like all medications, weight loss drugs can have side effects. Common ones include nausea, vomiting, diarrhea, constipation, and abdominal pain, especially when starting treatment or increasing the dose. These often improve over time. More serious but rare side effects can include pancreatitis, gallbladder problems, kidney problems, and severe allergic reactions. It's crucial to report any concerning symptoms to your doctor immediately. If side effects are severe or persistent, the doctor may advise adjusting the dosage or stopping the medication. Your Hi-Doctor account provides a private, RGPD-compliant chat for you to communicate directly with your doctor about any concerns.
