Chemotherapy treatment can affect multiple aspects of your digestive system, and constipation is a common concern among cancer patients. Understanding the relationship between chemotherapy and constipation is crucial for managing your comfort and well-being during treatment. This article explores why constipation occurs during chemotherapy and provides practical strategies for prevention and relief.
How Chemotherapy Affects Bowel Function
Chemotherapy can impact your digestive system in several ways, both directly and indirectly. The treatment may slow down the movement of food through your intestines, affect nerve signals controlling bowel movements, and cause changes in your eating and activity patterns. Additionally, many medications used alongside chemotherapy can contribute to constipation.
