Overview
Gastroenteritis is inflammation of the stomach and intestines, usually from a virus, bacteria or contaminated food and water. It causes a sudden run of vomiting and watery stools that most healthy adults recover from in a few days with rest and fluids. The main danger, especially in children and older people, is dehydration, so replacing lost fluids with ORS is the most important part of care.
Symptoms
- Watery diarrhea, often several times a day
- Nausea and vomiting
- Stomach cramps and bloating
- Mild fever and body ache
- Weakness and reduced urination from fluid loss
When to see a doctor
See a doctor if vomiting or diarrhea lasts more than two days, or sooner for young children and the elderly. Keep sipping ORS throughout.
Emergency — call 108 or go to the nearest hospital
- Signs of severe dehydration — no urine for many hours, sunken eyes, extreme drowsiness or cold clammy skin — or blood in the stools, seek care immediately
Causes
Viruses such as rotavirus and norovirus, bacteria from contaminated food or water, and poor hand hygiene. Common in the monsoon and summer.
