💊 Metformin
Metformin is a commonly prescribed medicine used to manage blood sugar levels, especially in people with Type 2 diabetes.
🧠 How It Works
Metformin helps by:
- Reducing glucose production in the liver
- Improving insulin sensitivity (your body uses insulin better)
- Decreasing sugar absorption from the intestines
👉 It does not cause insulin release, so it has a low risk of low blood sugar (hypoglycemia) when used alone.
✅ Common Uses
- Type 2 diabetes management
- Sometimes used for Polycystic ovary syndrome
- May help with weight control in some people
⚠️ Common Side Effects
- Nausea
- Diarrhea
- Stomach discomfort
- Loss of appetite
👉 These often improve after a few days or weeks. Taking it with meals helps reduce side effects.
🚨 Serious (but rare) risk
- Lactic acidosis
- Symptoms: weakness, breathing difficulty, unusual tiredness
- Requires immediate medical attention
💡 Important Tips
- Take with food to avoid stomach upset
- Avoid excessive alcohol
- Regularly check kidney function (important for safety)
- Don’t stop or change dose without consulting a doctor
👍 Bottom Line
Metformin is a first-line, well-studied, and effective medication for controlling blood sugar, with a strong safety profile when used properly.
