Crohn’s disease: An overview
Crohn’s disease is a chronic bowel disease that causes inflammation and irritation in a person’s digestive tract. It usually strikes the gut, and its hallmark symptoms are stomach pain and diarrhea. 
Doctors don’t have a clear understanding of what causes Crohn’s. But in some cases, it’s thought to involve “inappropriate” immune system activity. Basically, the immune system releases cells that produce inflammation even when no threat is present, and this inflammation causes problems. 
More than half a million people in the United States have Crohn’s disease, and that figure seems to be on the rise—though experts aren’t sure why. While it can present at any age, Crohn’s is most likely to show up during a person’s 20s. It may be slightly more common among women than men.
