According to researchers at Penn State Hershey Children’s Hospital, symptoms in children such as a delay in growth, weight loss, failure to gain weight, or persistent stomach pain with diarrhea or bloody stools can sometimes be associated with undiagnosed inflammatory bowel disease (IBD), namely Crohn's disease, a chronic inflammatory condition of the digestive tract. “Growth charts are one of the most important things we look at with children because sometimes a slower growth rate is the only sign of IBD, especially with Crohn's disease,” explained a pediatric IBD specialist at Penn State Hershey Children’s Hospital, Dr. Marc Schaefer in a news release. Blood analysis and endoscopy exams are also used to diagnose Crohn's disease and differentiate it from other IBDs, such as ulcerative colitis. The causes underlying IBD are unknown, although family history has been suggested as playing a role. “If a family history of IBD is present, there is an increased risk for a child to get it, but it's not definitive” said Dr. Tolulope Falaiye, also a pediatric IBD specialist.
