It often appears with other health conditions, especially anxiety and depression. IBS may have a relationship to alterations in the gut immune system, meaning it involves the immune cells and causes inflammation, but it's not an autoimmune process that causes tissue damage, as seen with Crohn's. There's no single cause of IBS, but likely related to factors such as alterations in gut motility, brain-gut interactions, stress, history of food poisoning, and genetic predisposition.

Having IBS doesn't mean you'll develop Crohn's or vice versa-they are two separate disorders. An autoimmune disease means the immune system mistakes healthy tissue for a foreign invader, so immune cells attack tissues and can cause long-term damage. The most noticeable difference between the two disorders is that while IBS is a functional disorder, Crohn's disease is a chronic inflammatory disease related to autoimmunity. Both conditions can also significantly impact your quality of life. Aside from both being gastrointestinal disorders, they can share many of the same symptoms.
