The fear of pooping is like a phobia. Parents will often ask why their child continues to be afraid to poop and, therefore, refuses to poop even after their child's poop stops hurting. Continuing to fear pain in the absence of pain seems irrational. Although there was a reason to be afraid in the past, that reason no longer exists. Just like a fear of bees can persist long after the first sting, the fear of pooping can persist long after the first painful poop. Such fears require treatment with exposure therapy.
In exposure therapy, phobic fears are neutralized by gradually and repeatedly exposing people to the object or the situation that evokes that fear. In the case of a fear of pooping, the child's fear of pain decreases little by little each time he passes stool and does not experience pain. The number of pain-free bowel movements needed to neutralize or extinguish the fear varies from child to child depending on various factors such as the age at which constipation began and the child's current level of maturity and cooperation.Regardless of these individual differences, however, the number of painless bowel movements required is always going to be large, which is why the treatment of functional constipation takes so long.
