Who qualifies for Semaglutide
When considering a Semaglutide online doctor consultation, our EU-licensed doctors look for specific criteria to ensure your safety and the medication's effectiveness. Semaglutide (a GLP-1 receptor agonist) is primarily approved for adults with a BMI of 30 or higher (obesity) or a BMI of 27 or higher (overweight) with at least one weight-related comorbidity such as type 2 diabetes, high blood pressure, or high cholesterol. They also assess for contraindications like a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), severe gastrointestinal disease, or pancreatitis. Your full medical history helps the doctor determine if Semaglutide is the right fit for you.
What Semaglutide actually does (and doesn't do)
Semaglutide works by mimicking a natural hormone called GLP-1. This hormone tells your brain you're full, slows down how fast food leaves your stomach, and helps your body produce more insulin when blood sugar is high. This leads to reduced appetite and better blood sugar control, which can result in weight loss over time. It's important to understand that Semaglutide is a tool, not a magic bullet. It works best when combined with lifestyle changes like a healthy diet and regular exercise. Realistic weight loss typically occurs gradually, often over several months, and varies from person to person. It doesn't guarantee immediate or extreme weight loss without effort on your part.
Side effects and when to stop
Like all medications, Semaglutide can cause side effects. The most common ones include nausea, vomiting, diarrhea, constipation, and abdominal pain. These usually improve over time as your body adjusts. However, it's crucial to be aware of more serious signs. If you experience severe abdominal pain (which could indicate pancreatitis), persistent vomiting, signs of kidney problems (like decreased urination), or allergic reactions (swelling, difficulty breathing), you must contact a doctor immediately. Our doctors will provide clear instructions on what to look for and when to seek urgent medical advice. Maintaining electrolyte balance and hydration, as discussed below, can help mitigate some common side effects.
