What does Metformin decrease?

  1. Hepatic glucose production

  2. Insulin sensitivity

  3. Pancreatic beta-cell function

  4. Glucagon secretion

The correct answer is: Hepatic glucose production

Metformin is a medication commonly used to treat diabetes. It works by decreasing the production of glucose in the liver, which helps to lower blood sugar levels. Options B, C, and D are incorrect because metformin does not affect insulin sensitivity, pancreatic beta-cell function, or glucagon secretion.
