What additional risk factor is known to contribute to diabetic neuropathy?

High blood pressure is a significant additional risk factor that contributes to the development of diabetic neuropathy. This condition is a common complication of diabetes, where prolonged elevated blood sugar levels lead to nerve damage. High blood pressure can exacerbate this by affecting blood flow and causing further damage to blood vessels that supply nerves, which is crucial for their health and function. Elevated blood pressure can lead to more chronic complications in diabetic patients, making it essential for managing both blood glucose and blood pressure to minimize the risk of neuropathy.
