Who qualifies for weight loss medication

Weight loss medications, such as GLP-1 receptor agonists like semaglutide or tirzepatide, are powerful tools, but they are not for everyone. When you complete your online medical questionnaire, an EU-licensed doctor assesses several factors to determine if the medication is appropriate for you. Generally, doctors look for:

• A Body Mass Index (BMI) of 30 or higher (obesity).
• A BMI of 27 or higher (overweight) with at least one weight-related comorbidity, such as type 2 diabetes, high blood pressure, or dyslipidemia.
• No personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
• No history of pancreatitis, severe gastrointestinal disease, or kidney issues that would contraindicate the medication.
• Not pregnant, planning pregnancy, or breastfeeding.
• No history of eating disorders or other conditions that make the treatment unsafe.

The doctor remains the gatekeeper; they will only issue a prescription if it is safe and medically appropriate for your specific health profile.

What weight loss medication actually does (and doesn't do)

Weight loss medications work in different ways to support your weight management journey. GLP-1 receptor agonists, for example, mimic a natural hormone that helps regulate appetite, slow stomach emptying, and improve blood sugar control. This can lead to reduced hunger, increased feelings of fullness, and, consequently, a lower calorie intake. Many patients experience significant weight loss, often 10-15% or more of their body weight over several months, when combined with diet and exercise.

However, these medications are not a magic bullet. They are most effective when used as part of a comprehensive weight management plan that includes lifestyle changes like a healthy diet and regular physical activity. They do not work instantly; it takes time for the body to adjust and for the medication to achieve its full effect. Expect a gradual process, not overnight results, and understand that consistent effort on your part is crucial for long-term success.

Side effects and when to stop

Like all medications, weight loss treatments can have side effects. Common ones for GLP-1 receptor agonists include nausea, vomiting, diarrhea, constipation, and abdominal pain, especially when starting treatment or increasing the dose. These are often mild and temporary, improving as your body adjusts.

More serious, though rare, side effects can include pancreatitis, gallbladder problems, and kidney issues. It is crucial to be aware of these and to report any severe or persistent symptoms to your doctor immediately. You should stop the medication and seek urgent medical attention if you experience:

• Severe abdominal pain that radiates to your back (potential pancreatitis).
• Yellowing of the skin or eyes (jaundice), severe upper right abdominal pain, fever, or chills (potential gallbladder problems).
• Signs of a severe allergic reaction, such as swelling of the face, lips, tongue, or throat, or difficulty breathing.

Your Hi-Doctor will provide detailed information on potential side effects specific to your prescribed medication. Always follow their instructions and never stop taking your medication without consulting a healthcare provider.
