Overview
Dehydration happens when the body loses more fluid than it takes in, leaving too little water to work normally. It is a common and serious risk in India's heat and during bouts of vomiting and diarrhea, and it is especially dangerous for babies and the elderly. Mild dehydration is easily corrected by drinking fluids and ORS, but severe dehydration can lower blood pressure and harm the organs, so the warning signs must be recognised early.
Symptoms
- Thirst and a dry mouth
- Passing less urine, which is dark in colour
- Tiredness, dizziness and headache
- Sunken eyes and, in babies, a sunken soft spot and few wet nappies
- Fast heartbeat and confusion when severe
When to see a doctor
See a doctor if you cannot keep fluids down, or for a child or elderly person with signs of dehydration. Keep sipping ORS meanwhile.
Emergency — call 108 or go to the nearest hospital
- No urine for many hours, sunken eyes, extreme drowsiness, cold clammy skin or fainting — signs of severe dehydration, seek care immediately
Causes
Vomiting, diarrhea, high fever, heavy sweating in the heat, and not drinking enough fluids, especially during illness.
