Constipation and diarrhea are experienced often by people with cancer. When you are constipated, you may have fewer bowel movements than what is normal for you. Your bowel movements may be hard or dry, and more difficult to pass. Changes in bowel function can be caused by changes to your body’s metabolism. These can be caused by disease, medications, dehydration or changes in daily habits and activities that disrupt your bodily functions.
Medications That Can Cause Constipation
- Pain medications
- Anti-nausea medications
It is important to treat constipation for your comfort and quality of life. When your platelet counts are low (thrombocytopenia), you are at increased risk for rectal bleeding while constipated.
