Primary constipation is caused by disrupted regulation of neuromuscular function of in the colon and the rectum, and also disruption of brain–gut neuroenteric function. [21] Secondary constipation is caused by many other different factors such as diet, drugs, behavioral, endocrine, metabolic, neurological, and other disorders. [ 21 ]
The total removal of the colon, called a colectomy or resection of affected parts of the colon may be needed if part of the gut dies (for instance toxic megacolon), or if there is a localized area of dysmotility.
