Your Tummy Timeline
1 - 2 days
Vomiting and diarrhoea can happen on their own or together. When they happen together, it is called gastro-enteritis. Gastro-enteritis is caused by a tummy bug, usually from contaminated food or close contact with someone who already has symptoms. Vomiting usually lasts between 6 and 12 hours and diarrhoea between 24 and 48 hours.
Usually, there is no specific cure and you need to let the illness run its course. Drink plenty of liquids to make sure you don’t become dehydrated. You don’t need to take anti-diarrhoea medicine unless you need to shorten the length of time your diarrhoea lasts – for example, if you need to take a long-haul flight. Children should not take anti-diarrhoea medicine.
2 - 5 days
You should generally start to feel better but it may take up to 5 days for your diarrhoea to clear. Continue to drink plenty of liquids to avoid dehydration.
