Heat exhaustion and abdominal cramps

Heat exhaustion develops when heat exposure and sweating place strain on the body's cooling and fluid systems. Abdominal muscles may tighten or ache during this process, especially after physical effort. [Heat Exhaustion](/conditions/heat-exhaustion/) can also involve headache, thirst, fatigue, dizziness and ongoing sweating.

Fluid loss may contribute to [Dehydration](/conditions/dehydration/). Abdominal pain that is severe, localised, persistent or unrelated to exertion needs separate medical assessment rather than being assumed to be heat-related.

Stop activity and move the person to a cool, shaded or air-conditioned area. Loosen clothing, place a cool damp cloth on the skin and let them rest. If they are alert and able to swallow, offer small sips of water; do not force fluids if they are vomiting or drowsy.

Avoid returning to heat while symptoms remain. Note associated [Excessive Sweating](/symptoms/excessive-sweating/), [Dizziness](/symptoms/dizziness/) or [Headache](/symptoms/headache/) because these details help a clinician judge severity.

Call emergency services for confusion, collapse, seizure, loss of consciousness, inability to drink, severe breathing difficulty or very hot skin with worsening symptoms. Seek urgent medical assessment if cramps, weakness, vomiting or dizziness do not improve after cooling.

Ask whether the episode was heat exhaustion, how to replace fluids safely, and how long to avoid strenuous activity. Tell the clinician about the setting, exertion, sweating, drinks taken and any [Dark Urine](/symptoms/dark-urine/) afterward.
