What is Diarrhea?
Diarrhea refers to the passage of loose or watery stools three or more times a day. Often diarrhea may cause pain or discomfort in the abdomen and/or rectum, but many times it does not. Patients with cancers of the gastrointestinal tract, including the stomach, colon, rectum often experience diarrhea. In addition, diarrhea may be a side effect of the cancer treatment, especially radiation therapy and chemotherapy. Diarrhea caused by cancer treatments may continue for up to 3 weeks after the treatment has been completed or stopped. Other common causes of diarrhea in cancer patients include bacterial and viral infections, anxiety, and supplemental feeding containing large amounts of vitamins, minerals, sugar, and electrolytes. Patients who are constipated may also have leakage of diarrhea.
What Can I Do to Prevent Diarrhea?Unlike many other side effects of cancer and its treatment, thereare specific actions that you can take to help prevent or minimizediarrhea, including:
- Make changes in your diet.
- Eat bland, low fiber foods such as boiled white rice, cheese, boiled chicken, and mashed potatoes.
- Eat foods high in protein, calories and potassium, but low inresidue such as cottage cheese, eggs, baked potatoes, cooked cereals,bananas, macaroni and pasta, white toast, and smooth peanut butter.
- Eat small amounts of food 5-6 times throughout the day, instead of three large meals.
- Add nutmeg to foods in order to slow down the movement of material through the intestines.
- Increase fluid intake. Try to drink about 3 quarts of fluid per day, unless your doctor or nurse tells you not to do so. This will help to prevent dehydration and malnutrition. Specific points to keep in mind include:
- Do NOT drink coffee, tea, alcohol, or milk or milk products, since they can make the diarrhea worse.
- Drink sports drinks, such as Gatorade, which help to replace certain electrolytes lost in the diarrhea.
- Serve clear liquids, including clear fruit juices (apple,cranberry, grape), ginger ale, and water.
- Liquids served at room temperature may be less likely to causeadditional diarrhea than cold or hot beverages.
- Take measures to promote comfort.
- Clean the rectal area well after each bowel movement. Use warm water and soap, and pat dry with a soft towel. This will help to prevent anal burning.
- Inspect area daily for red, scaly or broken skin. Report this to your doctor or nurse.
- Use sitz baths, or soak in a warm bath.
- Ask your Doctor or Nurse about using creams to help withdiscomfort in the anal area. Water repellent creams, such as A &D Ointment are very effective. Your doctor may also order a local anesthetic ointment that can be applied to the rectum.
- Use a room deodorizer if odor is a problem.

- Try to stay in a quiet, restful environment.
- Whenever possible, stay in an area with close access to abathroom, if needed in a hurry.
