Diarrhoea and vomiting are common in adults, children and babies. They're often caused by a stomach bug and should stop in a few days.
The advice is the same if you have diarrhoea and vomiting together or separately.
How to treat diarrhoea and vomiting yourself
Diarrhoea and vomiting can usually be treated at home. The most important thing is to have lots of fluids to avoid dehydration.
Do
-
stay at home and get plenty of rest
-
drink lots of fluids, such as water or squash – take small sips if you feel sick
-
carry on breast or bottle feeding your baby – if they're being sick, try giving small feeds more often than usual
-
give babies on formula or solid foods small sips of water between feeds
-
eat when you feel able to – it may help to avoid foods that are fatty or spicy
-
take paracetamol if you're in discomfort – check the leaflet before giving it to your child
Don’t
-
do not have fruit juice or fizzy drinks – they can make diarrhoea worse
-
do not make baby formula weaker – use it at its usual strength
-
do not give children under 12 medicine to stop diarrhoea
-
do not give aspirin to children under 16
How long diarrhoea and vomiting last
In adults and children:
- diarrhoea usually stops within 5 to 7 days
- vomiting usually stops in 1 or 2 days
Diarrhoea and vomiting can spread easily
Stay off school or work until you've not been sick or had diarrhoea for at least 2 days.
If you have a high temperature or do not feel well enough to do your normal activities, try to stay at home and avoid contact with other people until you feel better.
To help avoid spreading an infection:
- wash your hands with soap and water frequently
- wash any clothing or bedding that has poo or vomit on it separately on a hot wash
- clean toilet seats, flush handles, taps, surfaces and door handles every day
- do not prepare food for other people, if possible
- do not share towels, flannels, cutlery or utensils
- do not use a swimming pool until at least 48 hours after your symptoms stop
