My 7-year old son has held in his bowels for a few years now and I am worried that it can cause medical issues for him years down the road. The longest he has gone without a BM is 3 weeks and that is while he was on Miralax! He had been going about once a week for about a month or so but it has now been 11 days. I don't think the doctors really understand this very much. The first doctor I took him to about this said that it was impossible for him to have gone longer than 4 days without a bowel movement (he was about 4 years old then).
my son, now 7yrs old, had a bad issue with being able to go. he had held it until he couldnt anymore and he ended up going in his pants or trying to hold it between cheeks alot and we mistaked it for him pooping himself. The smell was horrid and it had the same smell everytime and we knew when he would go because it smelled so familiar each time. I took him to my doctors and he had suggested giving him the orange syrup to help him go, he said he was constipated, but he was on the orange stuff, eating a ton of bran each day, and no matter what we fed him (he ate healthy) he would manage to have a very solid movement everytime. until just over the past year, he had that problem, but he seems to have gotten over it just recently. I use to catch him trying go and he was in so much pain, and I think thats why he was holding it because it hurt so much, But I told him he needs to go whenever he feels like he has to go, as soon as he feels like he has to go, or it is going to hurt worse next time or more if he holds it longer. He goes regularily now, but not daily like my other kids, and I do catch him in pain sometimes, but he hasnt held it for quite some time.
He says that he has to wait until it hurts. Of course I have tried to explain to him that it won't hurt if he does not wait but he has Aspergers and it pretty much doesn't matter what I say, it is just an Aspi thing. What I do now is take away his computer until he decides to go. Part of me feels this is punishment and I don't want to punish him for stuff that he has no control over but I do feel he has control of this.
I agree, aspergers is hard to deal with trying to make him understand things. It does take this poopy issue to a different level. I think that if he is healthy, eats well, doesnt have any adverse reactions to holding it in, that it may not be too harmful, but I am far from being a doctor.
I hope talking to him, and explaining things over and over that maybe he will come to understand the importance of going when he needs to, and not when he feels he starts to feel pain. Make sure he finishes his meals and eats a proper amount for his age and size, and make sure he eats a lot of fruit and veggies and no soda/juice boxes, or other junk and maybe he can start to feel he has to go more often. That may not be an issue, he could be eating perfectly and still not going enough, but hopefully it will work itself out.
I would also keep on with your doctor and maybe try to consult a professional about his aspergers and maybe they can give you some assistance to teach him better about health and bathroom breaks... maybe they could give you some more skills on how to get him to learn quicker? I dont know, I hope I offered some good advice, it was only meant to help.
