Tenesmus is the feeling that you constantly need to pass stools, even though your bowels are already empty. It may involve straining, pain, and cramping.
Pain - passing stool; Painful stools; Difficulty passing stool
Tenesmus usually 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. Such diseases are called motility disorders.
Persons with tenesmus may push very hard (strain) to try to empty their bowels, but they pass little stool.
If you feel that you are constipated, try to increase your fluid and fiber intake.
Call your health care provider if
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.
What to expect at your health care provider's office
The doctor will examine you and ask questions such as:
- Time pattern
- Did this develop recently?
- Is it the first time you have had tenesmus?
- Does the feeling come and go, or is it constant?
- Symptom history
- Dietary history
- Have you eaten anything unusual or uncooked?
- Have you been at a picnic, gathering, or similar event recently?
- Have you had any medical problems in the past?
- Have any other people in your family or social group experienced similar problems?
The physical examination may include a detailed abdominal examination. A rectal examination is performed in most cases.
