Metformin helps reduce insulin resistance in diabetes. Insulin resistance is characteristic of Type 2 Diabetes, and it develops over time with increased blood sugar levels. 

However, Type 1 Diabetes can also develop insulin resistance if blood sugar levels have been above normal limits for a long time. This condition is sometimes called double diabetes. 

Some experts believe that Metformin can be given to people with Type 1 Diabetes without insulin resistance as it may help manage blood sugar levels better. But some don’t believe in this practice. They only prescribe Metformin if you have developed insulin resistance.

Studies also suggest that Metformin can be useful in Type 1 diabetes patients for the following reasons:

1. Decreases cholesterol levels
2. Helps manage weight
3. Improves insulin sensitivity
4. Reduces the risk of a heart condition. 

It is best to consult with your doctor and follow his instructions while taking medication for diabetes. You may or may not be prescribed Metformin.
