Managing Diabetes When It’s Hot Outside

Here in the Lowcountry, the “summer heat” can often continue well into early fall. For people with diabetes, these hotter months can increase their risks of complications.

“Higher temperatures call for different diabetes management techniques,” says registered dietician Kim Edwards, RD, a certified diabetes educator at Beaufort Memorial LifeFit Wellness Services. “While I advise staying active year-round, I also tell my patients to try to take some simple precautions when it’s hot outside.”

Her advice includes:

• Monitoring blood sugar more frequently and taking care of supplies: Many people with diabetes take insulin, which the body can absorb more quickly in the heat, resulting in low blood sugar (also called blood glucose) levels. Frequent monitoring may be needed to help with adjustments in medication dosing or diet changes.

“Heat and humidity can affect injectable medications as well as glucose monitoring supplies, which can lead to false readings,” she says. “Keep these stored in cool locations or insulated cooler bags away from the heat and sun.”

• Staying hydrated: Higher temperatures can cause the body to dehydrate more easily. This raises our thirst response, leading to more fluid consumption.

“Drink plenty of water to help keep the body hydrated,” Edwards says. “Avoid the urge to consume drinks containing sugar that could cause blood sugar levels to spike.”

• Use sunscreen to avoid sunburns and sun poisoning: Any type of sunburn can cause extra stress on the body, and stress can lead to higher blood sugar levels. Always keep SPF 30+ sunscreen on all exposed skin

"Be aware that some medications also increase the sensitivity to the sun, putting people at a higher risk for sunburns,” Edwards adds.

• Wear proper shoes: Hot weather brings out flip-flops and sandals. It is important for people with diabetes to wear protective shoes because they can develop nerve damage that decreases sensation to hot surfaces and sharp objects.

“For those with high blood sugar, simple cuts can lead to infection and take a lot of time to heal,” Edwards says. “So avoid going barefoot or wearing any shoes that do not properly cover the feet.”

• Exercise safely: Plan exercise around cooler parts of the day and stay in shaded areas. It may also be necessary for some diabetics to monitor blood sugars before, during and after exercising.

“Again, stay hydrated,” Edwards says. “And keep snacks available in case your blood sugar goes too low.”

Diabetes doesn’t have to get in the way of summer fun. Following these simple tips can assure you stay safe and healthy in almost any weather.
