Crohn's disease typically presents with symptoms such as abdominal pain, diarrhea, intestinal obstruction, complications of nutritional disorders, iridocyclitis, oral ulcers, anemia, and liver diseases. A preliminary diagnosis can be made based on these specific clinical manifestations. X-ray enterography can reveal intestinal lesions. It is important to maintain a reasonable daily routine. During active phases, bed rest should be observed, and a diet high in energy and calories but low in fat should be provided. Treatment involves a combination of medication and surgery. Crohn's disease tends to recur and has a protracted course. (Please take medication under the guidance of a professional physician.)
