Constipation

Constipation is the passage (usually with discomfort) of infrequent, hard, dry stool. If you have constipation, you may also notice bloating, increased gas, cramps, or pain. Constipation affects about half of people with cancer and about 3 out of 4 of those with advanced cancer. It can lead to nausea and a decreased appetite.

Risk factors for developing constipation include:

  • Taking opioid pain medicines
  • Lack of physical activity
  • Low-fiber diet and less food intake
  • Decreased fluid intake and dehydration
  • Bed rest
  • Depression
  • Getting certain chemotherapy drugs (such as vincristine and vinblastine)

If constipation develops, your doctor will try to determine the cause then take appropriate measures to treat the problem. Be aware of your bowel patterns, try to stay active, try to eat high fiber foods, and try to drink at least 3 quarts of fluid each day unless your doctor instructs you otherwise. Tell your doctor if you go more than 2 days without a bowel movement.
