Inflammatory bowel disease is usually divided into two types, ulcerative colitis and crohn's disease. Both diseases are chronic diseases, and diarrhea and oral ulcer may occur. However, the typical symptom of ulcerative colitis is pus and blood in the stool, so the preliminary judgment can be made from the stool. The most critical examination is a colonoscopy to see if there is any change in the bowel and where it is.

　　Inflammatory bowel disease can be divided into remission and onset. Symptoms are very mild or no symptoms is the remission period, diarrhea, abdominal pain and other symptoms recurring is the attack period. In the onset period, the purpose of treatment is to control the disease, reduce the symptoms, so that the disease into remission; In remission, the goal is to maintain the remission and keep the symptoms from happening. The key to treating crohn's disease is to suppress the inflammatory response in the gut, which is the immune response in the gut. Ulcerative colitis and crohn's disease are called inflammatory bowel disease, the method of treatment is very similar, commonly used drugs are 5- amino salicylic acid, hormones, immunosuppressive agents, biological agents and so on.

　　How do you know if it's better after treatment? The first thing to look for is relief of diarrhea, hematochezia, and abdominal pain. Then do colonoscopy to see what the ulcer and inflammation is, if the ulcer has grown, called mucosal healing. Finally, we need to take some mucous membrane for pathology. If the pathological results also show inflammation, it is called tissue healing. After tissue healing occurs, the patient's condition can be considered to be under control.
