My daughter has the same problem. Her doctor gave her an OTC magnesium citrate to get things moving, and for a while we were giving her enima's as well, which was not fun for either of us.
But let me tell you this: aside from chronic constipation, the doctor used another term "encompresis". The best way I can explain it is like using perfume. When you put perfume on in the morning, within an hour or so you can no longer smell it. That is because you have become oversensetized to the smell. Chronic constipation causes the same thing; the older, harder poop pushes against the sphinctor until they loose the ability to feel that they have to go, in other words, they are oversensetized to the feeling. Then the newer, softer poop eeks out around the harder stuff and it ends up in their underware. The thing is, they cant even feel they are doing it, and they are so used to the smell that they cant smell it either. I know how frusterating this can be...we have been dealing with this in one way or another for my daughter's entire life.
The one thing that has been consistanly working well for my daugther is one cap full of miralax mixed with water once a day. It isnt a normal laxative; all it does is draw more water into the bowel to keep things moist, and it is safe enough to use every day.
I hope this helps you!
