Speak to your doctor or dietitian for advice about diarrhoea. They can work out what’s causing it and how to treat it.

Read more about diarrhoea and how it is managed.

  • Eat small meals often.
  • Drink as much as you can manage, to help prevent dehydration.
  • It can help to avoid spicy foods, alcohol, fruit juice, tea and coffee.
  • Do not stop eating fruit and vegetables, unless your doctor or dietitian has told you to. They are important for your health and can help to make your poo more solid.
  • If you have very bad diarrhoea, you may need to replace salts and fluids that you have lost. Eat salty and sugary foods, or drink sports drinks that say they are isotonic on the label. Or drink a rehydrating drink such as Dioralyte®.
