At present, Crohn’s disease cannot be cured, because the cause of Crohn’s disease is not known, and only able to control the symptoms through medication, such as mesalazine, etc., and there is a possibility of relapse. Crohn’s disease may be due to the patient’s autoimmune function abnormalities caused by chronic damage to the intestinal mucosa. Since the patient’s autoimmune function cannot be completely corrected, Crohn’s disease cannot be completely cured. Crohn’s disease can be treated by applying drugs such as mesalazine, azathioprine, ursinumab, etc. Surgery is required in severe cases. The disease can get better with treatment, and some patients can also remit on their own. However, most patients have recurrent episodes that do not heal, and some of them need surgery due to complications during the course of the disease. Specific treatment should be consulted with specialized physicians, and medication should be applied appropriately according to the doctor’s prescription.
