Diabetic neuropathy is a type of nerve damage common in people with diabetes. Glucose (blood sugar) levels cause injury to the nerves throughout the body. There are four main types of diabetic neuropathy that include peripheral, autonomic, radiculoplexus and mononeuropathy. The areas most commonly affected by diabetic neuropathy are the lower extremities being the legs and feet. Symptoms of diabetic neuropathy include pain, numbness, tingling, digestive problems, urinary tract issues, and heart complications. The symptoms can be relatively mild for some, but for others, diabetic neuropathy is a painful and debilitating condition. Diabetic neuropathy is common, but it can be prevented or maintained by having a healthy lifestyle and maintaining control over your blood glucose levels.
