Nerve Damage
Damage to nerve cells is called "neuropathy." Nerve
cells are like insulated wires. When blood sugar is high, the sugar
causes damage to the insulation of the nerve. After time, the nerves
become unable to send signals through the body the way they should.
Nerve damage can happen slowly, and you very well might not even
notice that you are beginning to lose feeling in your feet and hands
(a symptom of neuropathy).
Besides loss of feeling in your feet and hands, there are other
signs that you have nerve damage. You may sweat more than normal
or feel light-headed when you stand up. You might also find it difficult
to tell when your blood sugar is low. You may have stomach and/or
bowel problems. You may experience difficulty in urinating, and
you may have bladder or kidney infections. Some people also experience
sexual problems. Men can have impotence. Women may experience decreased
vaginal lubrication and pain during sexual intercourse.

People with diabetes are more likely to develop damage to nerve cells than other people. The longer you have diabetes, the greater the chances that you may suffer from nerve damage. The Diabetes Control and Complications Trial (DCCT) was a study that took 10 years to complete, of people with type 1 diabetes. The purpose of the DCCT was to see if keeping blood sugar levels under tight control affected complications from diabetes. The study showed that tight control may reduce your chance of getting neuropathy by up to 60%.
- feet and lower legs tingle, burn, ache or throb
- numbness in feet, lower legs, or hands
- no pain from cuts, bruises, or injuries to feet or hands
- diarrhea that will not stop

Symptoms of neuropathy may come and go. Also, symptoms may be less noticeable when blood sugar levels are closer to normal range.
There are many treatments for neuropathy including various medications, dietary changes, and tight control of blood sugars. If you have any of the symptoms on the list above, tell your diabetes healthcare team so you can get the help you need.
How To Prevent Or Delay Neuropathy
- Keep
your blood sugar levels close to normal range. (Discuss your target
range with your diabetes healthcare team.)
- Lower
your blood pressure, if high.
- If
you smoke, stop! Smoking can also damage nerve cells.
- Exercise
daily to improve blood flow to your feet and hands.
- Report
any symptoms to your doctor or diabetes healthcare team.
