Diabetics at risk in extreme heat

Extreme heat poses serious risks for people with diabetes, as their ability to regulate body temperature is often impaired, particularly if complications like neuropathy, kidney disease, or cardiovascular problems are present, according to an article published in Medscape. Heat waves can increase hospital admissions by up to 25%, with older, overweight, insulin-treated patients at the highest risk of heatstroke, dehydration, or circulatory collapse.

High temperatures also affect diabetes therapy. Heat and fluid loss can reduce insulin effectiveness, accelerate absorption — raising risk of hypoglycemia — and worsen blood glucose control. Many medications commonly used by people with diabetes — such as diuretics, beta-blockers and antidepressants — further impair heat tolerance. Treatment plans may need adjustment during extreme heat.

Recommended safety measures include:

·       Adjusting daily routines to avoid midday sun and staying hydrated.

·       Monitoring blood glucose more frequently, since both high and low levels can occur more easily.

·       Protecting feet from burns or injury (especially with neuropathy).

·       Properly storing insulin and test supplies in cool conditions (36–46°F) and away from direct sunlight.

·       Keeping insulin pumps and continuous glucose monitors within manufacturer-specified temperature ranges, as heat can damage insulin, disrupt dosing, and impair device function.
