1. Why do cancer patients have diarrhea?
Diarrhea is a common digestive disorder in cancer patients. The duration and severity of diarrhea depends on the cause. Some causes of diarrhea in cancer patients include:
Cancer treatments: Some cancer treatments can cause diarrhea. These include chemotherapy, radiation therapy, immunotherapy, targeted therapy, and bone marrow transplants. Surgery can cause diarrhea if part of the intestine is removed. Infection: Cancer treatment can make a patient more susceptible to infection. Those infections can cause diarrhea and antibiotics are used to treat this. Cancer: Some cancers can cause diarrhea. These include neuroendocrine tumors, colon cancer, lymphoma, medullary thyroid cancer, and pancreatic cancer.
2. Why should cancer patients with diarrhea eat less fiber?
Dietary fiber provides roughage and has the ability to stimulate bowel movements. Generally, patients should consume at least 28 grams of fiber per day to promote gut health. The main sources of fiber are fruits, vegetables, whole grains, nuts and dried beans. However, a common side effect of cancer treatment is diarrhea. If you have treatment-related diarrhea, you should follow a low-fiber diet and limit your fiber intake to about 10 grams per day.
A low-fiber diet is better tolerated with diarrhea because it will not stimulate bowel movements too much and will be easier to digest. To find out how much fiber is in a serving, patients should read food labels or look up nutrition websites. Patients should choose foods with 2 grams of fiber or less per serving. Below is a summary of high-fiber foods and low-fiber foods. Patients can refer to it to build a balanced, reasonable diet.
