Expert advice on health and fitness - House Call

"Since it runs in my family, what can I do now to prevent or delay diabetes?"

PREVENTING OR DELAYING DIABETES

Q There are several members in my family who have been victimized by diabetes, and they have had to find ways to deal with the disease that affects so many Black people. I have a grandmother, uncle and two cousins who are affected in different ways by diabetes. I have heard that there are ways to keep diabetes from becoming a part of your life. Since it runs in my family, what can I do now to prevent or delay the disease? K.W., Atlanta

A With the disease being so prevalent in your family, you are wise to do what you can to avoid the effects of diabetes.

In answer to your question about prevention, there are many scientists who believe diabetes, both Type 1 and Type 2, can be prevented. Type 1 diabetes, which usually affects children and young adults, is believed to be caused by an allergic-like reaction--possibly to insulin, the pancreas or some substance in the pancreas. If so, doctors say that giving the affected person small injections of insulin could prevent the disease.

A Medical authorities say Type 2 diabetes is more prevalent among African-Americans and adults over 45, accounting for up to 95 percent of cases. It may be associated with an inherited defect that reduces a person's sensitivity to insulin. New medications and lifestyle changes (including routine exercise and a balanced diet) may reduce the risk of Type 2 diabetes.


Comments:
At the present time, there is NO known way to prevent immune-mediated diabetes (type 1) from occurring. Two large-scale clinical trials known as the Diabetes Prevention Trial (DPT) I and II both failed to prevent type 1 diabetes from occurring with injected or oral insulin administration, though researchers did learn a great deal about identifying patients who are at risk for developing this autoimmune condition.

The evidence on type 2 diabetes, however, is fairly conclusive that type 2 diabetes CAN usually be prevented by limiting caloric intake and increasing activity.
