Metformin is primarily used for which type of diabetes?

• A. Type 1 diabetes
• B. Type 2 diabetes
• C. Gestational diabetes
• D. Prediabetes

Answer: (B)

Metformin is used mainly for type 2 diabetes because it tackles two core problems of that condition: excess hepatic glucose production and reduced insulin sensitivity. By lowering glucose produced by the liver and improving how the body responds to insulin, it helps control fasting and postprandial glucose without usually causing hypoglycemia when used alone. In type 1 diabetes, where the primary issue is autoimmune destruction of insulin-producing cells, metformin alone cannot substitute for insulin. Gestational diabetes is typically managed with insulin as the first-line therapy, with metformin used in some cases but not as the standard initial treatment. Prediabetes may be managed with lifestyle changes and, in high-risk individuals, metformin can be used to help prevent progression to diabetes, but it is not the primary therapy for established diabetes. Thus, metformin is best associated with type 2 diabetes.
