13) Rectal Tenesmus
Rectal Tenesmus is a symptom of Irritable Bowel Syndrome that can be best described as the sensation of having the urge to defecate, and which remains even after defecation has been achieved. In other words, patients with rectal Tenesmus always feel that their bowel movements are incomplete. The sensation of Tenesmus is not always congruent with the actual presence of fecal matter remaining in the rectum. Rectal Tenesmus is typically associated with constipation. As a symptom, it can develop in cases of gastroenteritis, ulcerative colitis, parasitosis, IBS, and rectal cancer.
