Does heat exhaustion raise blood sugar?

No, heat exhaustion does not typically raise blood sugar levels. Heat exhaustion occurs when the body loses too much water and electrolytes due to excessive sweating, leading to dehydration and an imbalance in bodily fluids. While heat exhaustion can cause various symptoms such as fatigue, dizziness, nausea, and heavy sweating, it does not directly affect blood sugar levels.

In contrast, heatstroke, a more severe heat-related condition, can lead to hyperglycemia (high blood sugar levels) due to the body's stress response. During heatstroke, the body releases hormones like adrenaline and cortisol to redirect blood flow to essential organs, which can cause a temporary increase in blood sugar levels.

Therefore, heat exhaustion is not typically associated with elevated blood sugar levels, but heatstroke can cause hyperglycemia. It's important to differentiate between heat exhaustion and heatstroke and seek appropriate medical attention if experiencing heat-related symptoms, especially if you have pre-existing conditions like diabetes that can be affected by changes in blood sugar levels.
