Condition Basics What is diabetic neuropathy? Diabetic neuropathy is nerve damage caused by diabetes. Over time, high blood sugar levels can damage nerves throughout your body.
There are several types.
Peripheral neuropathy. This is damage to peripheral nerves Autonomic neuropathy. This is damage to autonomic nerves Atypical neuropathies. One type affects just one nerve. It's called mononeuropathy. It often affects a nerve in the wrist or foot. It can also affect a nerve that controls eye muscles. Another type affects many nerves. It's called polyradiculoneuropathy. It often affects nerves in the back and chest. These types of nerve damage happen all of a sudden. They can get better with time.What causes it? Over time, high blood sugar levels from diabetes can damage nerves throughout your body. The higher your blood sugar levels, the more likely you are to have nerve damage. Also, the older you get and the longer you have diabetes, the more likely you are to have nerve damage.
What are the symptoms? Symptoms depend on which nerves are injured. You may have burning or shooting pain in your arms and legs. Or you may not be able to feel pain, especially in your feet. This can lead to serious infections if sores aren't treated. Other symptoms may include problems with digestion, urination, and blood vessels.
How is it diagnosed? Your doctor will do a physical exam. They will ask about your health and current symptoms, including how well you can feel light touch, temperature, vibration, and movement. You'll also be asked about any symptoms such as pain, weakness, or urinary or digestive problems. You may need a nerve test for a diagnosis.
How is diabetic neuropathy treated? Treatment involves keeping blood sugar levels in your target range. This will not cure the nerve damage, but it can help keep the damage from getting worse, and the pain might get better. Other treatments, such as medicines for pain or digestive problems, depend on your symptoms.

Take your medicines exactly as prescribed. Call your doctor or nurse advice line if you think you are having a problem with your medicine. Try to keep blood sugar in your target range. Follow your meal plan to know how much carbohydrate you need for meals and snacks. A registered dietitian or certified diabetes educator can help you plan meals. Try to get at least 30 minutes of exercise on most days. Check your blood sugar as many times each day as your doctor recommends. Take and record your blood pressure at home if your doctor tells you to. To take your blood pressure at home: Ask your doctor to check your blood pressure monitor to be sure it is accurate and the cuff fits you. Also ask your doctor to watch you to make sure that you are using it right. Do not use medicine known to raise blood pressure (such as some nasal decongestant sprays) before taking your blood pressure. Avoid taking your blood pressure if you have just exercised or are nervous or upset. Rest at least 15 minutes before you take a reading. If you smoke, quit or cut back as much as you can. Smoking can increase your risk for peripheral artery disease (PAD). PAD can make neuropathy worse. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good. If you drink alcohol, try to drink less. Your risk of harm from alcohol is low if you have 2 drinks or less per week .
