Crohn’s disease is a serious inflammatory disease that occurs anywhere in the intestinal tract and has an unclear cause, suspected to be genetic and autoimmune, mostly in young men and women. Specific clinical symptoms include abdominal pain, diarrhea, loss of appetite, weight loss, anemia, and in severe cases, disease in the area between the mouth and the anus. Since the cause of Crohn’s disease is not obvious, it needs to be diagnosed by colonoscopy, gastroscopy, CT and other examinations, and once diagnosed, it needs to be treated immediately under the guidance of a doctor. Mild cases can be treated with medication and tailored to the body’s condition, while severe cases require immediate surgery, which can easily recur after surgery, and need to be kept in check for a specified period of time. It is also necessary to pay attention to diet and rest to avoid deterioration of the disease.
