Welcome to HW, I too was diagosed at a young age, I was 8. I have had CD now for 20yrs (diagnosed anyway symptoms 3 yrs prior...mainly C anf joint pain). My pediatric GI made me drink 2 ensure plus drinks a day plus 3 meals once I was off TPN and able to eat again. You may want to talk to your GI about
nutritional suppliments being that malabsorption is a big issue with CD. I also tend to suffer severly from joint pain, which can also be part of CD as can many other things you can find more info about
CD and other issues that CAN but not always accompany CD at www.ccfa.org
My family also thought I just didnt want to go to school, then Christmas break came and I was still having the same problems (and the D started) luckily from the main onset of symptoms I was Dx in a couple of weeks. Hopefully your son can be managed on meds and hope to one day to go into remission...some remissions last longer than others, mine was 1 year.
Dx with Crohn's 1987, symptoms as early as 1984.
