Who qualifies for Semaglutide

Doctors look at specific criteria to determine if Semaglutide is appropriate. Generally, Semaglutide is prescribed for adults with a Body Mass Index (BMI) of 30 kg/m² or greater (obesity), or a BMI of 27 kg/m² or greater (overweight) with at least one weight-related comorbidity such as high blood pressure, type 2 diabetes, or high cholesterol.

Contraindications include a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), pancreatitis, or severe kidney disease. During your online consultation, the doctor will carefully review your medical history to ensure your safety and suitability for treatment.

What Semaglutide actually does (and doesn't do)

Semaglutide is a GLP-1 receptor agonist. It mimics a natural hormone your body produces, GLP-1, which helps regulate blood sugar and appetite. Here's what it does:

• Reduces appetite: You feel fuller for longer, leading to reduced food intake.
• Slows gastric emptying: Food stays in your stomach longer, contributing to satiety.
• Helps control blood sugar: It stimulates insulin release and decreases glucagon secretion, which is beneficial for metabolic health.

What it doesn't do is provide instant, guaranteed weight loss. Semaglutide is a tool to support weight management, not a magic bullet. Realistic timelines show significant weight loss accumulating over several months, often alongside lifestyle changes. It works best as part of a comprehensive plan.

Side effects and when to stop

Like all medications, Semaglutide can cause side effects. Common ones include nausea, vomiting, diarrhea, constipation, and abdominal pain, especially when starting treatment or increasing the dose. These are usually mild and temporary.

More serious, though rare, side effects can include pancreatitis, gallbladder problems, kidney problems, and allergic reactions. You should stop taking Semaglutide and seek immediate medical attention if you experience severe abdominal pain, yellowing of the skin or eyes, or signs of a severe allergic reaction (e.g., swelling of the face or throat, difficulty breathing). Always discuss any concerns with your prescribing doctor.
