Cancer: Home Treatment for Constipation

Getting Started

These ideas can help you manage constipation caused by cancer or cancer treatment. If your doctor has given you instructions to treat constipation, be sure to follow them.

  • Drink plenty of fluids.
    • If you have heart failure or kidney failure, talk to your doctor about what amount of fluid is right for you.
    • Avoid alcohol. It can increase dehydration.
  • Include high-fibre foods in your diet each day.

    These foods include fruits, vegetables, beans, and whole grains. For example, have a bran muffin or bran cereal for breakfast. Eat a piece of fruit for an afternoon snack.

  • Be more active.

    But check with your doctor before you increase your physical activity, especially if you're getting cancer treatments. Talk with your doctor about what kind of exercise and how much exercise will help you.

  • Schedule time each day for a bowel movement.

    A daily routine may help. Take your time and don't strain having a bowel movement.

  • Support your feet with a small step stool when you sit on the toilet.

    This helps flex your hips and puts your pelvis in a squatting position.

  • Take a fibre supplement, such as Benefibre or Metamucil, every day.

    Read and follow all instructions on the label.

  • If constipation continues, talk to your doctor.

    Your doctor may recommend an over-the-counter laxative such as Milk of Magnesia or RestoraLax. Read and follow all instructions on the label.

    • Check with your doctor before you use any non-prescription medicines for constipation.
    • Do not use laxatives on a long-term basis.
