Vomiting due to heat exhaustion

Heat Exhaustion develops when the body loses water and salts through sweating and cannot cool itself effectively. Vomiting may occur alongside excessive sweating, headache, dizziness, excessive thirst or weakness. Dark urine can suggest fluid depletion. Heat intolerance or symptoms after exertion in hot conditions can add context, but vomiting can also have other causes.

Stop exertion and move indoors or into shade. Remove extra clothing, cool the skin with wet cloths or a fan, and lie down with help nearby. If fully awake and able to swallow, take small, frequent sips of water or an oral rehydration drink. Do not force fluids into someone who is confused, faint or vomiting repeatedly.

Seek emergency help for confusion, fainting, seizure, inability to drink, worsening weakness, very hot skin, or symptoms that do not improve promptly with cooling. Urgent assessment is also needed when vomiting continues, urine becomes very dark or scarce, or dizziness prevents standing. Heat illness can progress quickly, especially in children, older adults and people with chronic conditions.

Ask whether the episode is consistent with Heat Exhaustion or Dehydration and whether you need examination or fluids. Share the duration of heat exposure, activity, fluid intake, sweating, urine changes, medicines and any headache or dizziness.
