I'm new to the forum, mom to a beautiful 9 year old boy whose only symptom was stunted growth. One very thorough doctor and a referral to a gastroenterologist later, my world has been turned upside down with a diagnosis of Crohn's Disease. The GI says that we've caught it very early and his prognosis is excellent. He's putting him on some sort of liquid diet which he feels will also help with the growth issue. I'm confused though, why would Crohn's Disease cause poor growth in a child?
