The term fell out of favour over time due to the negative connotations. Furthermore, critics pointed out that it can be challenging to find organic pathologies for all symptoms, and so the practice of diagnosing that patients who had such symptoms were imagining them led to the disorder being meaningless, vague and a sham-diagnosis, as it did ...

The criteria include over 25% of defecations involving straining, 25% resulting in lumpy or hard stools, 25% requiring partial evacuation, 25% experiencing anorectal blockage or ...
Obstructed defecation is one of the causes of chronic constipation. [22] ODS is a loose term, [20] consisting of a constellation of possible symptoms, [7] caused by multiple, complex [23] and poorly understood [24] disorders which may include both functional and organic disorders. [18]
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]
Veronica Brown lived with chronic fatigue, depression, and anxiety for over 10 years before she learned they were early signs of Parkinson's disease. Here's how she found relief after diagnosis.
Extra-intestinal masses such as other malignancies can also lead to constipation from external compression. [32] Constipation also has neurological causes, including anismus, descending perineum syndrome, desmosis and Hirschsprung's disease.

In one study, 11 people with SRUS underwent laparoscopic ventral rectopexy. All of the patients showed resolved symptoms and mucosal injury one year after the procedure. In the long term, 1 patient developed recurrence after 4 years, and the other 7 who were evaluated in the long term did not develop recurrence. [13]
With recurrent straining, e.g. during difficult labour or long-term constipation, then stretch injury can damage the nerves supplying levator ani. If the pelvic floor muscles lose their innervation, they cease to contract and their muscle fibres are in time replaced by fibrous tissue, which is associated with pelvic floor weakness and incontinence.
