Crohn's disease early in its onset is characterized by symptoms such as abdominal pain, diarrhea, and intestinal obstruction. As the condition progresses, it can lead to anemia, nutritional disorders, eye involvement, joint involvement, and liver involvement. It is important to maintain a reasonable daily routine, eating multiple small meals that are high in calories but low in fat, and include a variety of vegetables. During active phases, bed rest should be observed, and a diet high in nutrition but low in fat should be provided, combined with medical and surgical treatments. The symptoms of Crohn's disease are prone to recurrence, and the prognosis is not particularly good. It is essential to actively cooperate with the doctor’s treatment.
