Crohn’s disease is a chronic digestive disease that causes inflammation of the digestive tract. It is also referred to as an inflammatory bowel disease (IBD).
Although it most commonly impacts the lower part of the small intestine, Crohn’s disease can affect any part of the digestive tract, from the mouth to the anus. Swelling that extends deep into the lining of the impacted organ can cause pain and can make the intestines empty frequently, resulting in diarrhea.
