“Known collectively as inflammatory bowel disease (IBD), Crohn’s disease and ulcerative colitis are painful, medically incurable diseases that attack the digestive system, causing symptoms including abdominal pain, persistent diarrhea, rectal bleeding, fever, and weight loss.
Crohn’s disease may attack anywhere along the digestive tract, while ulcerative colitis inflames only the large intestine (colon). In addition to the impact on the GI tract, in some patients, IBD may also affect the joints, skin, bones, kidneys, liver, and eyes.”
