Chen Xueqing, Department of Gastroenterology, The First Affiliated Hospital of Guangzhou Medical College: First of all, I suggest you to do a dye magnification endoscopy to clarify whether it is ulcerative colitis. I am not sure if you are diagnosed with ulcerative colitis because you said you have an attack once a year and you didn’t tell me what happens when you have an attack, such as the nature of the stool, with or without blood, and so on. Secondly, if you are diagnosed with ulcerative colitis, I regret to tell you that the disease cannot be cured at this time, and the best scenario is to control the symptoms with medication to maintain remission. The specific method depends on the extent of the disease and the response to the medication to decide.
