What is rectal tenesmus?

Rectal tenesmus is a medical term that refers to a persistent and often uncomfortable sensation of needing to have a bowel movement, even when the rectum is empty or only partially filled. It is the feeling of incomplete evacuation of the bowels and the persistent urge to defecate or pass stool, even after attempting to have a bowel movement.

This sensation is often accompanied by a sense of rectal pressure, discomfort, or a feeling of fullness in the rectal area. People experiencing rectal tenesmus may frequently go to the toilet, strain during bowel movements, or experience only small amounts of stool passing. It can be distressing and disruptive to daily life.

Rectal tenesmus can be a symptom of various underlying medical conditions, such as inflammatory bowel disease, irritable bowel syndrome, hemorrhoids, colorectal cancer, infections, or other gastrointestinal issues. If you experience rectal tenesmus, it is important to consult a healthcare professional to determine the underlying cause and receive appropriate treatment.
