Metformin is one of the most commonly prescribed medicines in the world for managing Type 2 Diabetes. With the rapid increase in diabetes cases in India and globally, this medication has become a first-line treatment recommended by doctors. It is affordable, effective, and generally safe when taken as prescribed.
In this article, we will discuss Metformin uses, benefits, side effects, dosage information, and price in India in simple and easy-to-understand language.
What is Metformin?
Metformin is an oral anti-diabetic medicine that belongs to a class of drugs called biguanides. It helps control blood sugar levels in people with Type 2 Diabetes.
Unlike insulin, Metformin does not increase insulin production. Instead, it works by:
- Reducing glucose production in the liver
- Improving insulin sensitivity
- Decreasing sugar absorption in the intestines
Because of these actions, it helps maintain stable blood sugar levels.
Uses of Metformin
Metformin is primarily used for:
1. Type 2 Diabetes
It is the first-line medicine prescribed to control high blood sugar levels. It helps prevent complications such as kidney damage, nerve problems, and heart disease.
2. Prediabetes
Doctors sometimes prescribe Metformin to people with prediabetes to prevent progression to Type 2 Diabetes.
3. PCOS (Polycystic Ovary Syndrome)
Metformin is often used in women with PCOS to improve insulin resistance and regulate menstrual cycles.
4. Weight Management
Some patients may experience mild weight loss while taking Metformin, especially those with insulin resistance.
