TY - JOUR T1 - ULcerative colitis AU - Torpy JM, Lynm C, Golub RM Y1 - 2012/01/04 N1 - 10.1001/jama.2011.1889 JO - JAMA SP - 104 EP - 104 VL - 307 IS - 1 N2 - Inflammatory bowel diseases (IBD) such as ulcerative colitis and Crohn disease make the bowel (intestine ) inflamed, irritated, swollen, and unable to function in a healthy way. Ulcerative colitis affects the large intestine (the colon) and the rectum but does not involve the small intestine (the part of the bowel that connects the stomach to the colon and that is responsible for almost all the body's food digestion and absorption of nutrition). Crohn disease affects both the small intestine and the colon. SN - 0098-7484 M3 - doi: 10.1001/jama.2011.1889 UR - http://dx.doi.org/10.1001/jama.2011.1889 ER -
