Most bowel infections go away after a few days.

It’s important that you drink plenty of fluids, including water and oral rehydration drinks. This is to avoid dehydration. Oral rehydration drinks are available from pharmacies and some supermarkets. Some brands are also available as icy poles. Diarrhoea causes a lot of fluid to be lost from the body. Take special care of vulnerable people like the very young, older people and those in poor health. Children who refuse water and oral rehydration drinks can be given diluted apple juice in the short-term. Babies who are breastfeeding need to be breastfed more often to keep up their fluids. Formula-fed babies should be given oral rehydration solution or water for the first 12 hours. After that, give their normal formula in smaller, more frequent amounts.

Some people need antibiotics for bowel infections caused by parasites and bacteria.

If your symptoms persist, see a doctor.

Can bowel infections be prevented?

Many bowel infections can be prevented by taking care with what you eat and drink, and by following good hygiene practices. You should:

Cook foods such as meat and eggs thoroughly.

Wash your hands regularly, especially before touching food.

Avoid close contact with people who have a bowel infection.

When travelling to areas where clean water and food hygiene cannot be guaranteed, you should:

only use bottled water for drinking and teeth cleaning

avoid drinks with ice

choose freshly cooked foods that are served steaming hot

avoid raw or under-cooked foods (especially meat or seafood)

avoid fresh salads, peeled fruit, unpasteurised milk or milk products

avoid food from roadside stalls
