Damage to the defecation centre within the medulla oblongata of the brain can lead to bowel dysfunction. A stroke or acquired brain injury may lead to damage to this centre in the brain. Damage to the defecation centre can lead to a loss of coordination between rectal and anal contractions and also a loss of awareness of the need to defecate. [12]
It causes constipation and bloating. On listening to the abdomen with a stethoscope, no bowel sounds are heard because the bowel is inactive. [citation needed] It is a common side effect of some types of surgery, termed postsurgical ileus.

However, surgery remained a treatment of last resort. Largely because of the associated pain, many patients chose certain death over surgery. Although there has been debate as to who deserves the most credit for the discovery of general anaesthesia, scientific discoveries in the late 18th and early 19th centuries were critical to the eventual ...
Dr. P. Ravi Kiran, chief of colorectal surgery at Columbia University, said it would take a few days for Francis' bowels to start working again and for him to recover from the effects of anesthesia.
It can occur in both children and adults, and in both men and women (although it is more common in women). It can be caused by physical defects or it can occur for other reasons or unknown reasons. Anismus that has a behavioral cause could be viewed as having similarities with parcopresis, or psychogenic fecal retention. [citation needed]
The most common causes are thought to be immediate or delayed damage from childbirth, complications from prior anorectal surgery (especially involving the anal sphincters or hemorrhoidal vascular cushions), altered bowel habits (e.g., caused by irritable bowel syndrome, Crohn's disease, ulcerative colitis, food intolerance, or constipation with ...
