The most common cause of diarrhoea is a viral infection, but it can also be caused by:
- a bacterial infection
- contaminated food and water
- a reaction to food
- infection in other parts of the body.
Fluid or runny poos with or without the following symptoms:
- feeling unwell
- not interested in eating and drinking
- painful stomach cramps
- feeling weak
- be vomiting (which usually starts before the diarrhoea).
Your little one’s symptoms will usually settle down after a few days, but can last up to 10 days. If symptoms continue for longer or you are worried, call PlunketLine or your doctor.
Caring for your child at home
Medicine is not usually needed and the main treatment is to provide more fluids for your child to help them replace lost fluids. It’s usually better to give small drinks often, rather than large drinks less often.
If your child doesn’t want to drink and is vomiting often and/or has a lot of diarrhoea, they can become dehydrated and need to be checked by a doctor.
Treatment for a baby
It’s important to keep breast or bottle feeding your child and offer extra fluids. Offer your baby food and fluids from their normal diet if they’ve started to eat solids. Your baby may not be hungry, so follow their cues as to how much they eat, as drinking is the most important.
Treatment for an older child
Make sure your child keeps up their fluids, as kids can quickly become dehydrated. Water is generally the best choice, but they may also be interested in drinking milk. Try to avoid fizzy or sugary drinks like fruit juice or sodas.
Your child may not be as hungry as usual so offer them small amounts of food from their normal diet, bland non-greasy foods are ideal. Try to avoid grains, sugary or fatty foods.
