Crohn’s disease has survived for 30 years. Crohn’s disease, because it is a type of inflammatory bowel disease, has a complex etiology, which may be related to genetics or immunity. If Crohn’s disease is not cancerous, it is possible to survive for a long time. At the same time, Crohn’s disease is prone to a series of complications, such as acute perforation, intestinal obstruction, anemia and intra-abdominal inflammatory infections, etc. If Crohn’s disease does not present these conditions, it is possible to live for a long time.
