Weight Loss Medication and Diet: What to Eat for Best Results

Looking to get a Semaglutide prescription online in Spain, or any other EU country? You've come to the right place. Hi Doctor makes it simple, fast, and discreet.

How it works: get your Semaglutide prescription in 4 steps

  1. Fill the online medical questionnaire: It takes just 2–3 minutes to provide your medical history and current health status.
  2. A licensed EU doctor reviews your case in private: Our doctors assess your information carefully to determine if Semaglutide is safe and appropriate for you.
  3. If appropriate, you receive a valid electronic prescription within 24 hours: This prescription is delivered securely to your private account and by email.
  4. Pick up your medication at any EU pharmacy: Your electronic prescription is valid across the EU, making it easy to get your medication locally.

Who qualifies for Semaglutide

Our EU-licensed doctors follow strict guidelines to ensure your safety and the effectiveness of treatment. When considering a Semaglutide prescription, they look for specific criteria:

  • BMI: Typically, Semaglutide (a GLP-1 receptor agonist) is prescribed for adults 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 high blood pressure, type 2 diabetes, or high cholesterol.
  • Medical History: The doctor assesses your complete medical history, including any pre-existing conditions, allergies, or current medications.
  • Contraindications: Certain conditions, like a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), or a history of pancreatitis, may make Semaglutide unsuitable for you.

The doctor reviews every case individually to determine if Semaglutide is the right treatment for your weight management journey.

What Semaglutide actually does (and doesn't do)

Semaglutide is a GLP-1 receptor agonist. It works by mimicking a natural hormone in your body that targets areas of the brain involved in appetite regulation. This leads to:

  • Reduced Appetite: You feel fuller, faster, and for longer.
  • Slower Gastric Emptying: Food stays in your stomach longer, contributing to prolonged satiety.
  • Decreased Cravings: Many patients report fewer cravings for unhealthy foods.

It's important to understand that Semaglutide is not a magic bullet. It supports weight loss when combined with diet and exercise. Realistic timelines show that significant weight loss typically occurs over several months, with average weight loss ranging from 8% to 15% or more of initial body weight over a period of 1 to 1.5 years. It does not guarantee instant results or replace healthy lifestyle choices.

Side effects and when to stop

Like all medications, Semaglutide can have side effects. Most are mild to moderate and temporary, especially as your body adjusts to the medication. Common side effects include nausea, vomiting, diarrhea, constipation, and abdominal pain. These often lessen over time.

It's crucial to be aware of more serious, though rare, side effects and to know when to seek medical attention. If you experience severe abdominal pain (which could indicate pancreatitis), significant changes in vision, or symptoms of a severe allergic reaction (swelling of the face or throat, difficulty breathing), stop the medication and contact your doctor immediately. Our Hi Doctor chat allows you to communicate privately and auditable with your doctor about any concerns.
