Constipation is a condition of the digestive system where a person (or other animal) experiences difficulty in eliminating feces.
Some of the main causes of constipation include:
- Constriction, where part of the intestine or rectum is narrowed or blocked, not allowing feces to move past
- Paralysis, where peristaltic action is diminished or absent, so that feces are not moved along
- Excessive drying of feces, forming a hard bulk that cannot be eliminated
- Insufficient intake of food or dietary fiber, so that a suitable bolus is not formed
- Psychosomatic constipation, based on anxiety or unfamiliarity with surroundings
People often take laxatives to try to eliminate constipation.
