Metformin is one of the most commonly prescribed medicines for managing Type 2 Diabetes worldwide. It has been used safely for decades and is often the first-line treatment recommended by doctors. But what exactly is metformin? How does it work? And are there any side effects?
In this detailed health guide, we’ll cover everything you need to know about Metformin, including its uses, benefits, dosage, precautions, and more.
What is Metformin?
Metformin is an oral anti-diabetic medicine that belongs to a class of drugs called biguanides. It helps control high blood sugar levels in people with Type 2 Diabetes.
Unlike insulin injections, metformin does not increase insulin production. Instead, it helps the body use insulin more effectively.
How Does Metformin Work?
Metformin works in three main ways:
- Reduces glucose production in the liver
- Improves insulin sensitivity
- Decreases sugar absorption in the intestine
This combined action helps maintain stable blood sugar levels and reduces the risk of diabetes-related complications.
Main Uses of Metformin
Metformin is primarily prescribed for:
1. Type 2 Diabetes
It helps manage high blood sugar and prevents complications such as nerve damage, kidney problems, and vision issues.
2. Prediabetes
Doctors may prescribe metformin to people with prediabetes to delay or prevent the development of Type 2 diabetes.
3. Polycystic Ovary Syndrome (PCOS)
Metformin is sometimes used off-label to manage Polycystic Ovary Syndrome, as it improves insulin resistance and helps regulate menstrual cycles.
4. Weight Management (In Some Cases)
Although not officially a weight-loss drug, some people may experience mild weight reduction while taking metformin.
