Still, some researchers have theorized that some type of infection may have originally been responsible for triggering the immune system, resulting in the continuing and out-of-control cycle of inflammation that occurs in Crohn’s disease. Other evidence for a disorder of the immune system includes the high incidence of other immune disorders that may occur along with Crohn’s disease.
