Sold under Fortamet and Glucophage’s brand name, Metformin is a form of oral medicine given for people with type 2 diabetes. This medicine works by improving a person’s blood sugar levels and preventing episodes of diabetes attacks.

Since Metformin helps control blood sugar levels, is it also applicable in treating type 1 diabetes? Does it also work in providing medical alleviation to people with type 1 diabetes?

People who have been diagnosed with type 1 diabetes only follow insulin medications. Whether it be fast-acting or short-acting types, insulin shots are what individuals with the condition perform daily. But how about oral medicines?

Experts say that oral medications like Metformin can increase a person’s insulin sensitivity. People with type 1 diabetes need to lose weight and require a large basal insulin supply. Thankfully, Metformin can do just that! Additionally, it works well during adolescence. The only precaution to remember when taking Metformin is to keep the liver and kidney functioning.


Besides type 2 diabetes, people with type 1 diabetes are also prone to developing PCOS (polycystic ovary syndrome). It is a condition that women in their reproductive age experience. This hormonal disorder includes symptoms such as irregular periods, excess androgen, and polycystic ovaries.

The main treatment administered for PCOS is Metformin. It decreases the insulin levels of women with PCOS, making it a reliable treatment for people with type 1 diabetes. Even though it is unlikely to get prescribed Metformin if you have type 1 diabetes, there are a lot of testimonies that prove its effectiveness.
