In diabetes treatment, what role does Metformin play?

• A. Increases insulin production
• B. Decreases glucose production by the liver
• C. Enhances insulin sensitivity
• D. Inhibits glucose absorption in the intestines

Answer: (B)

Metformin is primarily recognized for its role in decreasing glucose production by the liver. In individuals with type 2 diabetes, the liver can produce excess glucose, contributing to hyperglycemia. Metformin acts primarily by reducing this hepatic glucose output, thereby lowering blood sugar levels.

This mechanism is crucial for managing diabetes, as it helps maintain better glycemic control without the risk of causing significant hypoglycemia, which can occur with other medications that increase insulin production. Unlike some other treatments for diabetes, Metformin does not rely on the patient's insulin levels, making it a versatile option for many patients.

By focusing on this reduction in liver glucose production, Metformin helps patients achieve better overall diabetes management, making it a foundational medication in treatment plans for type 2 diabetes.
