Vomiting and diarrhea in extreme summer heat may seem like a minor stomach issue, but doctors say they can become dangerous very quickly. When the body loses too much water and salts through loose motions or vomiting, dehydration sets in.
During a heatwave, dehydration happens faster because the body is already losing fluids through sweat. This can reduce blood flow to vital organs like the kidneys, brain, and heart, increasing the risk of serious complications.
Signs of dehydration to watch for:
- Very dry mouth or lips
- Extreme thirst
- Weakness or dizziness
- Headache
- Dark yellow urine or very little urination
- Fast heartbeat
- Confusion or fainting in severe cases
Why it becomes risky:
If the body doesn’t get enough water and electrolytes back, the kidneys may struggle to work properly. In severe cases, dehydration can lead to kidney injury, low blood pressure, heat exhaustion, or even organ damage.
What doctors advise:
- Drink water regularly, even if you don’t feel thirsty
- Take ORS (Oral Rehydration Solution) to replace lost salts
- Eat light foods like curd, banana, rice, or khichdi
- Avoid direct sun and rest in a cool place
- Seek medical help immediately if vomiting or diarrhea continues, or if there are signs of severe weakness or reduced urination
Doctors say: during a heatwave, vomiting and diarrhea should never be ignored—what looks like a simple stomach upset can quickly turn into a medical emergency due to dehydration.
