Crohn's disease commonly occurs in the terminal ileum and the right half of the colon. It is a type of inflammatory bowel disease with unknown causes and can occur in any part of the gastrointestinal tract. Clinically, it mainly presents with symptoms such as diarrhea, abdominal pain, and intestinal obstruction. However, it may also lead to complications like intestinal perforation and bloody stools, and can affect organs like the liver, joints, and skin. The condition tends to relapse frequently and is difficult to cure completely. Current treatments combine medication and surgery. During active phases of the disease, it is important to enhance nutrition, rest in bed, consume high-nutrient, low-fat foods, and utilize supportive therapies. (Please use medication under the guidance of a professional physician.)
