Sweat it: Diabetes and perspiration

Tip Did you know that diabetes can hinder your ability to sweat in hot weather? The human body perspires to cool itself off. If you aren't sweating, you run the risk of overheating at temperatures that some people with diabetes can't tolerate. It's very important to keep yourself hydrated and out of direct sun if you can. Past research shows that during hot weather people with diabetes have an increased number of emergency room visits, hospitalizations and deaths due to heat-related illnesses.

A recent Mayo Clinic survey revealed that most people with diabetes don't realize how dangerous hot weather can be. In addition to complicating blood sugar control, hot weather brings with it the risks of dehydration, sunburn, heat stroke, and damaged oral medications and insulin.

Pay attention to the weather in the area where you live, especially the heat index. High humidity makes hot weather more dangerous because it can further slow down the body's cooling process. Only about half the patients who responded to the Mayo Clinic survey knew the definition of the heat index--do you?

The formulary for these, as stated by CVS/Caremark (my pharmacy benefits provider), covers all test strips, lancets, and control solutions. I dutifully get my doctor to write up prescriptions for all of my testing needs, submit...
