GIP and GLP-1 Dual Agonism: How Tirzepatide Works

Looking for a Tirzepatide prescription online in Spain or elsewhere in the EU? You can get Tirzepatide through an EU-licensed doctor without a clinic visit. Hi-Doctor offers a convenient, online consultation service for just €25 every 28 days (cancel anytime) or €35 one-off.

How it works: get your Tirzepatide prescription in 4 steps

  1. Fill the online medical questionnaire: It takes just 2–3 minutes to provide your health details securely.
  2. A licensed EU doctor reviews your case in private: Our EU-licensed doctors individually assess your information to determine if Tirzepatide is appropriate for your health needs.
  3. If appropriate, you receive a valid electronic prescription within 24 hours: Your prescription is delivered to your private account and by email, ready to use.
  4. Pick up your medication at any EU pharmacy: Your electronic prescription is valid across the European Union.

Who qualifies for Tirzepatide

When reviewing your case for a Tirzepatide prescription, our EU-licensed doctors look for specific criteria. Generally, Tirzepatide is considered for adults with Type 2 Diabetes and/or obesity. For obesity, a Body Mass Index (BMI) of 30 kg/m² or higher is typically required. For individuals with weight-related comorbidities (like high blood pressure or high cholesterol), a BMI of 27 kg/m² or higher might qualify. The doctor will assess your full medical history to check for contraindications and ensure Tirzepatide is safe and appropriate for you.

What Tirzepatide actually does (and doesn't do)

Tirzepatide is a unique medication because it's a dual agonist, meaning it activates both GIP (Glucose-dependent Insulinotropic Polypeptide) and GLP-1 (Glucagon-Like Peptide-1) receptors. This dual action helps regulate blood sugar and promotes weight loss more effectively than targeting GLP-1 alone.

  • Blood Sugar Control: It stimulates insulin release when blood sugar is high and reduces glucagon, which raises blood sugar.
  • Appetite Regulation: It slows gastric emptying and influences brain signals to reduce appetite, helping you feel fuller for longer.
  • Weight Loss: Clinical trials show significant weight loss, often exceeding what's seen with GLP-1 medications alone. However, Tirzepatide is not a magic bullet; it works best alongside lifestyle changes like diet and exercise. Realistic timelines for noticeable weight loss vary, and consistent use is key.

Side effects and when to stop

Like all medications, Tirzepatide can cause side effects. Common ones include nausea, vomiting, diarrhea, and constipation. These are usually mild to moderate and often improve over time as your body adjusts. It's important to discuss any concerns with your doctor. Red flags that might require you to stop or seek immediate medical attention include severe abdominal pain, persistent vomiting or diarrhea leading to dehydration, or signs of pancreatitis. Always follow your doctor's advice and report any unusual or severe symptoms promptly.
