What is metformin commonly used for?

Metformin is widely recognized as a first-line medication for the treatment of Type 2 diabetes. It works primarily by decreasing gluconeogenesis in the liver, which reduces the amount of glucose released into the bloodstream. Additionally, metformin enhances insulin sensitivity, allowing the body to use insulin more effectively. This dual mechanism helps to control blood sugar levels in individuals with Type 2 diabetes.

Type 2 diabetes is characterized by insulin resistance and can often be managed initially with lifestyle changes and medications like metformin. This medication does not stimulate insulin production directly, making it distinct from treatments typically used for Type 1 diabetes, where the pancreas fails to produce sufficient insulin.

In contrast to other options, metformin is not used for insulin production in the pancreas, nor is it utilized for managing high blood pressure, further solidifying its role solely as a key intervention specifically for Type 2 diabetes management.
