* '''Hardening of the feces''': Improper [[mastication]], low [[dietary fiber]], [[dehydration]] and medications ([[aluminium]], [[calcium]], [[diuretic]], [[iron]]).
* '''Paralysis or slowed transit''': [[Hypothyroidism]], [[hypokalemia]], injured [[Anus|anal sphincter]], medications ([[loperamide]], [[codeine]], [[morphine]], [[tricyclic antidepressants]]) and severe systemic illness due to other causes.
* '''Constriction, where part of the intestine or rectum is narrowed or blocked''': [[Diverticulosis]], [[pelvic masses]] and [[stenosis]].
* '''Psychosomatic constipation''': [[Functional constipation]] and [[irritable bowel syndrome]].<ref>{{cite journal |author=Caldarella MP, Milano A, Laterza F, ''et al'' |title=Visceral sensitivity and symptoms in patients with constipation- or diarrhea-predominant irritable bowel syndrome (IBS): effect of a low-fat intraduodenal infusion |journal=Am.
