11 year old pooping pants all the time

[Victor547]

My nephew is 11 years old.  He is always pooping his pants and he smells all the time.  His parents have taken him to the doctors in the past.  The doctors gave them medicine to give my nephew  three times a day and they are supposed to give him an enima once a day at night.  They are not consistant with the treatment so it has not helped any.  When my nephew was younger he would hold his bowels as long as he could.  What happened over time is his bowels get very hard because he holds them so long and now his colon is stretched out.  (according to the doctors)  When my nephew is asked why he does this he replies by saying he doesn't know.  He is no longer allowed a day care because he can't keep his pants clean.  I don't know what the problem is but he he is getting older and the problem isn't improving.  If anyone has some information on what I should do, or if you have some insight on what could be causing an 11 year old to poop his pants I would love to hear it.  I would love to smack some sense in to his parents but I don't know if it is my place or not.  I can't figure out if this is mental or physical.  Please help with some information.

It sounds like the doctor was describing encopresis.  

If so,  he needs fiber.  When he says he doesn't know why this is happening,  it's because he really can't predict when this will happen.

I can't imagine parents not being concerned enough about this to follow doctor's orders!
