Nerve damage: One more reason to keep blood sugar under control

One of the most common problems associated with diabetes is nerve damage, known as diabetic neuropathy.

Among the nerve failures:

Peripheral neuropathy is a degeneration of nerves in the feet and hands. It decreases sensitivity to touch, such as from tight shoes or a stubbed toe, while heightening sensations of pain or itching. This form of neuropathy occurs slowly but progressively.

Autonomic neuropathy is damage to nerves that control bodily functions, such as digestion, urination, heart rate, blood pressure, sexual function and even sweating. Symptoms include digestive problems (bloating, nausea, constipation, abdominal pain), drops in blood pressure, urinary difficulties, impotence or vaginal dryness.

The older you get and the longer you've had diabetes, the more likely you are to develop neuropathy. Your best bet for prevention: Keep your blood sugar controlled over the long term. In addition to the medications your doctor prescribes, it's important to stay active, maintain a healthful weight and follow a diet low in simple sugars and saturated fats.
