People with chronic diseases like diabetes as well as people taking certain medications, including heart disease medications and diuretics, which are often used to treat complications of diabetes, are at increased risk of experiencing difficulties in the heat, even though they may be unaware of it.
Keep hydrated. Dehydration can happen to anyone in the heat. If you have diabetes, dehydration also can occur when blood glucose is not under control. When blood glucose is elevated, this can lead to an increase in the body's excretion of urine.
Watch for signs of heat exhaustion, especially if you are working/exercising outdoors. People with diabetes and other chronic diseases like heart disease are more susceptible to overheating.
Exercise in a cool place, early in the morning or later in the evening when temperatures may be more moderate.
Check blood glucose levels at least four times per day and more often if you are not feeling well. Heat can cause blood glucose levels to fluctuate. Carry plenty of water and snacks.
Store your blood glucose meter, strips and insulin in a cool, dry place. Do not store insulin in extreme temperatures.
