Who qualifies for Semaglutide

Semaglutide is a powerful GLP-1 receptor agonist. Doctors prescribe it 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. When a doctor reviews your case, they look for specific criteria:

• Your BMI: Does it meet the thresholds for prescription?
• Your medical history: Are there any contraindications, such as a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)?
• Current medications: Are there any potential interactions with other drugs you are taking?
• Other health conditions: Do you have severe kidney disease, pancreatitis, or gallbladder issues that would make Semaglutide inappropriate?

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

What Semaglutide actually does (and doesn't do)

Semaglutide works by mimicking a natural hormone in your body called GLP-1. This hormone targets areas in your brain that regulate appetite, making you feel fuller, reducing cravings, and slowing down stomach emptying. This leads to reduced calorie intake and, over time, weight loss.

It does:

• Help you feel full faster and for longer.
• Reduce hunger and cravings.
• Lead to gradual, sustainable weight loss when combined with diet and exercise.

It doesn't:

• Offer instant results. Weight loss is a gradual process that takes weeks and months.
• Work without lifestyle changes. Semaglutide is a tool, not a magic bullet.
• Guarantee a specific amount of weight loss for every individual.

Side effects and when to stop

Like all medications, Semaglutide can cause side effects. Most are mild and temporary, particularly during the initial weeks as your body adjusts to the dose. The most common side effects are gastrointestinal:

• Nausea (very common, especially when starting or increasing dose)
• Diarrhea or constipation
• Vomiting
• Abdominal pain

These usually improve over time. To manage them, try eating smaller, blander meals, staying hydrated, and avoiding fatty foods. If side effects are severe, persistent, or worsen, contact your doctor immediately. Less common but serious side effects can include pancreatitis, gallbladder problems, kidney issues, or severe allergic reactions. Always seek medical attention if you experience severe abdominal pain, yellowing of the skin/eyes, difficulty breathing, or significant swelling.
