Diarrhea Diarrhea can often occur in people with cancer as a side effect of chemotherapy, radiation, antibiotics, or surgery on the gastrointestinal tract. If more than 2 watery stools are passed each day, dehydration, weight loss, and nutritional deficiencies can result.
Malabsorption can be significant and nutritional problems result.
Fatique is one of the most obvious. However, poor nutritional health can also hinder cancer therapy effectiveness. It is important to take steps to treat diarrhea seriously whenever it occurs. Recommendations for managing diarrhea are based on whether or not surgery has been performed on the colon or rectum. Vitamin-mineral supplements may be recommended and should be discussed with your doctor.
