High Blood Fats Tied to Diabetic Nerve Loss

Diabetes patients with elevated levels of triglyceride fats are at increased risk of developing a serious complication called neuropathy -- the loss or damage of nerves that results in numbness, tingling and pain in the hands, arms, legs and feet, researchers say.

Diabetes is a disease in which the body doesn't produce or properly use insulin, a hormone that's needed to convert sugar, starches, and other foods into the nourishment and energy the body needs. This means the blood sugar (glucose) is too high (hyperglycemia). It affects an estimated 16 million Americans, of all races and ethnic groups, and about half of these people are older than 60. Diabetes affects many body systems and can lead to, or cause, other medical problems.

Those most at risk for diabetes:
-are overweight
-have a family history of diabetes
-are African American, Latino, Pacific Islander, Asian American, or Native American
-have a history of diabetes during pregnancy (gestational diabetes), or have had a baby weighing more than nine pounds at birth .

People with diabetes have a greater risk of heart attack, blood vessel disease, nerve damage, kidney disease, blindness, and are more likely to have high cholesterol levels. However, one of the most common problems caused by diabetes is diabetic neuropathy.

Diabetic neuropathy is a term that includes several nerve diseases. "Neuropathy" means "nerve disease." Diabetic neuropathy affects peripheral nerves -- those that are outside of the brain and spinal cord, such as nerves in the arms, legs, hands, and feet. Some elderly diabetics with neuropathy also develop a condition called diabetic myopathy (muscle wasting), in which the small muscles of the foot, as well as some other muscles, become thinner and weaker.

Can Diabetic Neuropathy Be Prevented?

In some cases, diabetic neuropathy can be prevented. Patients who follow their recommended self-care program are less likely to develop diabetic neuropathy. Tight control of blood sugar (keeping as near to normal levels as possible), following your diet and exercise plan, not smoking, and maintaining normal weight are all very important in preventing diabetic neuropathy. Regular, frequent visits to your health care provider are also important.
