Constipation and Chemotherapy

Constipation and chemotherapy

Just as each person is different, so is their reaction to cancer and cancer treatment. You may have severe, mild, or no side effects. Talk with your cancer care team about the side effects you might have. It helps to do this before treatment starts. There may be things you can do to manage or prevent some side effects. For instance, you can take steps to help prevent constipation during cancer treatment.

Some chemo can cause constipation or hard, dry stools that you have less often. Stool may also be difficult to pass. You can also become constipated when you're less active, take certain medicines, such as pain medicine or iron, or don't get enough fluid or fiber in your diet.

Call your health care provider if you aren't having bowel movements in the pattern that's normal for you. Your provider may suggest taking a laxative or stool softener. But don't take these measures without first checking with your provider.

What will help constipation?

These tips can help prevent constipation:

• Drink plenty of fluids to help keep stool soft. If you don't have mouth sores, try warm and hot fluids, including water, to help relieve constipation. Ask your provider how much liquid you should drink every day.

• Talk with your provider about your diet. You may be advised to increase your fiber intake. But this should be done only under the direction of your provider. There are some types of cancer and certain side effects of treatment for which a high-fiber diet is not advised. High-fiber foods include:

  • Bran.

  • Whole-grain breads and cereals.

  • Raw or cooked vegetables.

  • Fresh and dried fruit with skins.

  • Nuts and seeds.

  • Dates, raisins, prunes, and prune juice.

• Exercise every day. You may want to try a more structured exercise program, or simply go for a walk. Talk with your provider about the amount and type of exercise that's right for you.

Ask your providers what symptoms you need to tell them about right away. Examples of some serious problems include not having a bowel movement in 3 days, not being able to eat, or having pain, cramps, or vomiting that doesn't stop.

Talk with your providers about the medicines you can use to prevent constipation. If you have ongoing constipation problems, your providers can refer you to a dietitian or nutritionist. They can teach you more about eating certain foods and doing other things that might help solve the problem.
