My son has Crohn s disease which was diagnosed a year after his diagnosis of Celiac disease. He had no symptoms of Crohn s but due to his regular lab work for Celiac he was diagnosed in the early stages. He has recently had episodes in 2 week intervals of severe pain followed by vomiting which resolves within 24 hours. He then has a normal appetite and resumes eating. He is gaining weight and height at a normal pace. The inflammatory markers in his recent labs do not show any elevation, however the Gastroenterologist said it could be a partial blockage. If it is a partial blockage why does it resolve and then come back and will it get worse over time?
