Hot weather and diabetes can make for a potentially dangerous combination, according to a Mayo Clinic presentation at the 92nd Annual Meeting of the Endocrine Society in San Diego, California.

     "An increased risk of dehydration and damage to diabetes medications and equipment are some of the challenges patients may face during hot weather," says Adrienne Nassar, M.D., consultant in the department of internal medicine, and Curtiss Cook, M.D., endocrinologist, both at Mayo Clinic in Arizona.

     "People living with diabetes in hot climates need to be more aware of how heat affects management of their disease," Dr. Nassar advises. "Don't wait for high temperatures before taking precautions." The Mayo Clinic investigators recommend the following tips for patients with diabetes as temperatures begin to climb:

- Check sugar levels frequently throughout the day, especially during exercise, since blood sugars may fluctuate.

- On the road? Transport diabetes supplies and medications in an insulated bag protected by a cold pack. (Avoid freezing.)

- Avoid exercising in the heat, choosing instead to do so in an air-conditioned place.

- Wear light colour clothing made of fabrics that can "breathe."

- Protect your feet -- never walk barefoot on hot surfaces.

- Watch for signs of possible heat exhaustion, such as dizziness, fainting or excessive sweating. Seek medical attention if you experience symptoms.

- Maintain adequate hydration; avoid caffeinated or alcoholic beverages that can be dehydrating.
