Cancer Care: Controlling Diarrhea
A common side effect of cancer and cancer treatment is diarrhea. This is when you have loose, watery stools or pass stool more often than usual. There are many things that can cause diarrhea, such as:
If not controlled, diarrhea can cause you to quickly become dehydrated. It can also change the balance of nutrients and minerals in your body. Be sure to tell your healthcare provider about any changes in your bowel habits. You may need treatment.
Tips for controlling diarrhea
These steps can help you keep diarrhea from getting worse:
-
Limit the amount of fiber in your diet. Don't eat high-fiber foods such as whole-grain bread and brown rice. Instead, eat white bread and rice.
-
Eat foods rich in potassium, such as bananas, apricots, and potatoes. This can help replace potassium lost due to diarrhea.
-
Eat small, frequent meals that are easy to digest. Try the BRAT diet: bananas, white rice, applesauce, and toast.
-
Drink plenty of fluids. Water, juice, sports drinks, and flat light sodas, like ginger ale, are best. They can help replace fluids lost due to diarrhea.
-
Stay away from coffee, tea, and alcohol.
-
Don't eat foods that are fried, greasy, spicy, or sweet.
-
Limit milk products and how much milk you drink if these seem to make diarrhea worse.

| For breakfast, try eating toasted white bread and a banana. |
