Metformin is used primarily to manage what condition?

Metformin is primarily used to manage diabetes, specifically type 2 diabetes. It functions by improving the sensitivity of body tissues to insulin and reducing the amount of glucose produced by the liver. This helps lower blood sugar levels in individuals who have difficulty managing their diabetes through diet and exercise alone.

The use of metformin is a well-established part of diabetes management protocols and is often one of the first-line medications prescribed to individuals diagnosed with type 2 diabetes. Its effectiveness in lowering blood sugar levels while having a favorable safety profile makes it a cornerstone of diabetes treatment.

In contrast, the other options listed, such as cardiovascular disease, hypertension, and allergies, are conditions that require different treatment approaches and medications, which do not include metformin as part of their standard management.
