When receiving various treatments for Cancer it is not uncommon for patients to have problems with diarrhoea /diarrhea as a side effect. This can be caused by the Cancer treatment itself, infections, medications, anxiety or stress. The best way to control the problem is through your diet, and whatever the cause of the diarrhoea in your particular case you will probably find that a temporary change in your diet will help. When you begin to find the symptoms have reduced you can discuss going back to your normal diet with your medical team (including your dietitian).

Useful Tips to Prevent or Control the Diarrhoea / Diarrhea

  • Drink lots of fluids including water, fruit squashes and soups. Try to drink at least 8 to 10 cups of fluids during the course of the day.
  • Eat regular small and manageable meals.
  • Try to restrict your intake of alcohol and high caffeine drinks such as coffee, strong tea and high energy caffeine based drinks such as Red Bull.
  • Reduce your fibre / fiber intake by substituting wholemeal bread and cereals with white varieties.
  • Avoid fatty, greasy foods and highly spiced foods as these can irritate your bowel.
  • Cut down on raw and dried fruits, as well as vegetables that have skins e.g. potatoes, and vegetables with seeds or pips. Likewise cutting right down on beans and pulses is advisable.
  • Avoid large amounts of artificial sweeteners, and remember these are not just the ones you drop into your hot drinks, many of these sweeteners are found in sugar-free or diet food and drinks.


Remember this article is only a guideline. Always discuss any concerns you have with your medical professional, and before following any advice you read online or in books you should make sure that your medical specialist or dietitian agree with the advice you plan to follow. If your diarrhoea / diarrhea persists you should consult your doctor to determine the cause so he can provide appropriate treatment.

If your doctor, nurse or dietitian have already advised you to follow a specific dietary plan then you should continue with that diet unless they agree that the changes you plan could be beneficial and that you should try them out.

Thank you DDE, I guess a lot of people don't like to talk about their diarrhoea when they are undergoing Cancer treatment, it is just another way for them to feel helpless and miserable. Hopefully this article will help them to avoid the problem and give them back some of their dignity through what is already a very unpleasant time for them.
