Overview
Most diarrhoea is caused by an infection and gets better within a few days. The main risk is dehydration, especially in young children and older adults.
Symptoms
- Loose or watery stools three or more times a day
- Abdominal cramps
- Nausea or vomiting
- Fever
- Signs of dehydration: thirst, dry mouth and passing little urine
Causes and risk factors
Common causes are viral or bacterial infections from contaminated food or water. Others include medicines, food intolerances, irritable bowel syndrome and inflammatory bowel disease.
Diagnosis
Most cases need no tests. Stool and blood tests are done for severe, bloody or long-lasting diarrhoea.
Treatment
The most important treatment is replacing fluids with oral rehydration solution. Zinc is recommended for children. Antibiotics are only needed for some infections.
When to see a doctor
See a doctor if diarrhoea lasts more than a few days. Seek urgent care for blood in the stool, high fever, signs of dehydration, or diarrhoea in a baby.
