How does a higher HbA1c level increase the risk of diabetes complications?

A higher HbA1c level indicates that blood sugar has been poorly controlled over the past few months, increasing the risk of diabetes-related complications. These complications include cardiovascular disease, nerve damage (neuropathy), kidney disease (nephropathy), and vision problems (retinopathy). Consistently elevated blood sugar damages blood vessels and nerves, leading to long-term health issues. Keeping your HbA1c levels below the target range, typically below 7%, can significantly reduce the risk of complications. Regular HbA1c testing, along with a well-managed diabetes care plan, helps prevent these serious health problems.
