Diabetic neuropathy is a common and potentially serious complication of diabetes that affects the nerves, most often in the legs and feet. It occurs when high blood sugar levels damage the nerves over time, leading to a range of symptoms that can impact quality of life. These symptoms include pain, tingling, numbness, and even loss of sensation in the affected areas. When left untreated, diabetic neuropathy can result in unnoticed injuries, infections, and more severe complications, such as ulcers and amputations.
