Small bowel obstruction causes include post-adbominal surgery adhesions, foreign bodies and intussusception. Large bowel obstruction causes include neoplasms, hernias and constipation. Miscellaneous causes include, paralytic ileus and Down syndrome. Causes by organ system include, ovarian cancer, bowel strangulation and ascariasis. Mechanical obstruction can be caused by pregnancy, Hirschsprung's disease and Crohn's disease. Non-mechanical obstruction may be caused by ovarian torsion, pancreatitis and lead poisoning. Drug induced bowel obstruction can occur by intake of lanthanum carbonate, methscopolamine bromide, and teduglutide.
