“Inflammatory Bowel Disease,” or IBD is the name given to a group of illnesses that include:
1. Crohn’s disease, in which causes pain in the abdomen, diarrhea, and loss of weight, because the intestinal wall gets sore and swollen;
2. Ulcerative Colitis (UC), which is slightly different, because the swelling happens only in the colon. The symptoms are similar to Crohn's Disease, but kids with UC don't usually lose weight or have growth problems.
