Pathophysiology of ConstipationPathophysiology of Constipation
• Repeated avoidance of defecation :Repeated avoidance of defecation :* Stretches the rectum* Stretches the rectum
* Decreases propulsive power * Decreases propulsive power
* Loss of sensory & motor function* Loss of sensory & motor function
• Longer feces remains in rectum – harder it becomesLonger feces remains in rectum – harder it becomes• Passage of hard & large stool – painful fissurePassage of hard & large stool – painful fissure• Cycle of avoiding bowel movement – fear of painCycle of avoiding bowel movement – fear of pain• Functional constipationFunctional constipation
