Tenesmus is the feeling that you need to pass stools, even though your bowels are already empty. It may involve straining, pain, and cramping.
Tenesmus most often occurs with inflammatory diseases of the bowels. These diseases may be caused by an infection or other conditions.
It can also occur with diseases that affect the normal movements of the intestines. These diseases are known as motility disorders.
Persons with tenesmus may push very hard (strain) to try to empty their bowels. However, they will only pass a small amount of stool.
The condition may be caused by:
Increasing the amount of fiber and fluid in your diet can help ease constipation.
When to Contact a Medical Professional
Contact your health care provider if you continue to have symptoms of tenesmus that are constant or come and go.
Also call if you have:
- Abdominal pain
- Blood in the stool
These symptoms could be a sign of a disease that might be causing the problem.
