Here are some ideas for helping to manage diarrhoea. If you have diarrhoea which does not settle within a few days, see your GP.

Drink plenty of fluid

When you have diarrhoea, you may lose a lot of fluid and can become dehydrated.

Drinking fluid will not make your diarrhoea worse.

  • Take small, frequent sips of fluid.
  • Include water, broths or soups, weak cordial or diluted fruit juice.
  • You can get rehydration fluid from the chemist, or make your own (see recipe below).

Foods to avoid while your stomach is upset

Some foods can make you feel worse if you have diarrhoea. It may help to avoid these foods for a few days until you are feeling better:

  • high fibre foods, like wholegrains, nuts, seeds, legumes and dried fruit
  • coffee, alcohol, soft drinks and concentrated fruit juice
  • fatty, spicy or very seasoned foods
  • large amounts of milk or ice cream.

Getting back to your 'normal' way of eating

If you have had diarrhoea you may not feel like eating very much. Start with bland foods that are low in fibre such as:

  • white bread
  • crackers
  • rice
  • plain cooked eggs
  • canned or well-cooked fruit or vegetables.

Other advice

Yoghurt that has live cultures (such as Vaalia®) can help prevent diarrhoea

See your GP straight away if you:

  • have blood in your stools
  • have a fever or vomiting as well as diarrhoea, or if you feel very unwell
  • have less or no urination.
