Tenesmus is the urge to pass stool. This feeling can arise even if the bowels are already empty. Tenesmus most commonly involves straining, pain or cramping. This condition arises due to the inflammation of the bowels. The inflammation can be a consequence of any kind of infection or can occur as a part of any other motility disorder of the intestine. People who suffer from Tenesmus generally strain and push hard to pass stool.
Causes of Tenesmus:
-inflammatory bowel disease
-intestinal motility disorder
-cancer in the colorectal area

Before starting the treatment of Tenesmus, it is important to know the cause of the condition. The underlying cause of the condition should be treated first. This will help in improving the general condition of the patient and hence makes the treatment much easier.
The doctor starts the diagnosis by taking through history of the patient. While taking the history the doctor may start by asking the patient questions on the time of onset of the condition. That is if the Tenesmus has just developed in the recent past or if it has occurred before. If Tenesmus is constant or the need to empty the stool is intermittent.
Questions regarding the various symptoms may be asked like if any pain is present in the abdomen area or if it is cramping that is causing discomfort. History of diarrhea or vomiting or any other symptoms should be taken into consideration.
Diet history is also important. Question regarding the normal diet pattern are asked.
