Who qualifies for weight loss medication

Our EU-licensed doctors individually review each patient's medical history to ensure safety and appropriateness. Generally, weight loss medications like Semaglutide (Wegovy) or Tirzepatide (Mounjaro) are considered for adults with a Body Mass Index (BMI) of 30 or greater (obesity), or a BMI of 27 or greater (overweight) with at least one weight-related comorbidity such as high blood pressure, type 2 diabetes, or high cholesterol. The doctor assesses your current health status, existing conditions, and other medications to determine if a GLP-1 receptor agonist is suitable for you. Contraindications are carefully checked during this online consultation.

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

Medications like Semaglutide and Tirzepatide are GLP-1 (Glucagon-Like Peptide-1) receptor agonists. They work by mimicking a natural hormone that targets areas of the brain involved in appetite regulation. This leads to reduced hunger, increased feelings of fullness, and slower stomach emptying. The result is a significant reduction in calorie intake and, over time, weight loss. It's important to understand these are not 'magic pills.' They are most effective when combined with lifestyle changes, including a balanced diet and regular physical activity. Expect gradual, sustainable weight loss over several months, not overnight results. These medications support your weight loss journey but do not replace healthy habits.

Side effects and when to stop

Like all medications, weight loss treatments can have side effects. Common ones for GLP-1 agonists include nausea, vomiting, diarrhoea, and constipation, especially when starting treatment or increasing the dose. These are usually mild and temporary. More serious, but rare, side effects can include pancreatitis or gallbladder problems. It's crucial to report any severe or persistent side effects to your doctor immediately. You should also stop the medication and seek urgent medical attention if you experience signs of a serious allergic reaction, severe abdominal pain, or changes in vision. Your Hi-Doctor.ai online consultation includes guidance on managing side effects and understanding when to seek further medical advice.
