Early symptoms of Crohn's disease include abdominal pain and diarrhea, abdominal masses, and may also be accompanied by fever, anemia, and digestive nutritional disorders, and can affect joints, eyes, skin, and other organs. Some patients may have iritis, clubbed finger arthritis, oral ulcers, and chronic hepatitis. Crohn's disease is an inflammatory bowel disease of unknown cause, commonly occurring in the ileum and right half of the colon, with a tendency to be prolonged and recurrent, and is not easy to cure completely. Currently, treatment mainly involves medication combined with surgery to prevent complications. It is important to rest adequately and maintain a reasonable diet. (Please use medication under the guidance of a professional physician.)
