Some types of cancer and cancer treatments may cause stomach discomfort and diarrhea. Your doctor may recommend that you follow a fiber-restricted diet (also referred to as low-residue or low-fiber). A fiber-restricted diet reduces the amount and frequency of bowel movements, therefore reducing irritation to your digestive tract. Your healthcare team may also recommend a fiber-restricted diet if you have a colostomy or ileostomy, or recent intestinal surgery.
Suggestions for a fiber-restricted diet are listed below. When reading nutrition labels on packaged foods, look for foods that contain fewer than 2 grams of dietary fiber per serving. Ask for a referral to a registered dietitian (RD) to help you find out how much fiber you should be consuming.
