Doctor's Notes on Crohn's Disease FAQs about Symptoms, Causes, Treatment, Life Expectancy

Crohn's disease is a type of inflammatory bowel disease (IBD) that involves chronic inflammation of the digestive tract, from the mouth to the anus. It most commonly affects the end of the small intestine called the terminal ileum and the beginning of the large intestine called the cecum. It differs from ulcerative colitis, another type of IBD, which only affects the colon.

Symptoms of Crohn's disease depend on which part of the digestive tract is affected. Common symptoms of Crohn's disease include diarrhea, abdominal cramps, weight loss, fatigue, feeling unwell (malaise), pain with a bowel movement, blood in the stool, rectal bleeding, bloating, or constipation. Crohn's disease is chronic, but the symptoms are not continuous. Most people experience "flares" which are times in which symptoms appear or get worse. Symptoms of Crohn's improve or go away completely ("remission") until another flare occurs and most people generally feel well when the disease is in remission.
