In patients with diabetes, which of the following is a significant benefit of good glycemic control?

Reduced risk of cardiovascular disease
Decreased frequency of emergency room visits
Elimination of diabetes complications
Improved mental health

The correct answer is: Reduced risk of cardiovascular disease

Achieving good glycemic control in patients with diabetes has a significant benefit in reducing the risk of cardiovascular disease. High levels of blood glucose over time can lead to damage to blood vessels and nerves, increasing the risk of cardiovascular complications such as heart attacks, strokes, and other heart-related issues. Numerous studies, including the Diabetes Control and Complications Trial (DCCT) and the UK Prospective Diabetes Study (UKPDS), have shown that maintaining good blood glucose levels can substantially lower the rates of cardiovascular events in individuals with diabetes. While effective glycemic management can contribute to decreasing emergency room visits and may improve mental health, it does not completely eliminate the risk of diabetes complications. Thus, the primary and well-supported connection between good glycemic control and health outcomes is the significant reduction in cardiovascular disease risk.
