affects the cells lining the intestine, it can cause
(watery or loose stools). If you have diarrhea that continues for more than 24 hours, or if you have pain and cramping along with the diarrhea, call your doctor. In severe cases, the doctor may prescribe a medicine to control the diarrhea. If diarrhea persists, you may need intravenous (IV) fluids to replace the water and nutrients you have lost. Often these fluids are given as an outpatient and do not require hospitalization. Do not take any over-the-counter medicines for diarrhea without asking your doctor.
Tips to Help Control Diarrhea
Some tips that your doctor may recommend include:
- Drink 8-12 cups of clear fluids a day. This will help replace fluids you have lost through diarrhea. Mild, clear liquids, such clear broth, sports drinks such as Gatorade, or ginger ale, are best. If these drinks make you feel nauseous, try diluting them with water. Drink slowly and make sure drinks are at room temperature. Let carbonated drinks lose their fizz before you drink them.
- Ask your doctor if you should try a clear liquid diet to give your bowels time to rest. A clear liquid diet does not provide all the nutrients you need, so only stay on this diet for the time highlighted by your doctor.
- Eat five or six small meals throughout the day instead of three large meals.
- Include certain foods in your diet, such as:
- Eat low-fiber foods—Low-fiber foods include white bread, white rice or noodles, creamed cereals, ripe bananas, canned or cooked fruit without skins, cottage cheese, yogurt without seeds, eggs, mashed or baked potatoes without the skin, pureed vegetables, chicken, or turkey without the skin, and fish.
- Avoid certain foods or drinks, such as:
- Foods that cause gas (eg, dried beans, cabbage, broccoli, soy products)
- High-fiber foods, which can lead to diarrhea and cramping (eg, whole grain breads and cereals, raw vegetables, beans, nuts, seeds, popcorn, fresh and dried fruit)
- Milk and milk products, including ice cream
- Fried, greasy, or spicy foods
- Hot or very cold liquids
- Tea with caffeine
- After having a bowel movement, use care when wiping your anal area.
- Tell your doctor if your diarrhea lasts for more than
24 hours or if you have pain and cramping along with diarrhea.
While diarrhea is a common side effect of chemotherapy, there are steps that you can take to control it. If you are not finding any relief, be sure to tell your doctor right away. In some cases, you may need to take medicine or have tests done to look for an infection. Remember that your doctor and other healthcare providers are there to support you during your treatment.
In some cases, your doctor may prescribe medicine, like loperamide or antibiotics, and order tests to look for an infection.
