The treatment of ulcerative colitis is actually a series of comprehensive treatment, not one or two aspects, and clinicians have to develop different treatment plans based on the patient’s typology and clinical grading, which overall mainly includes the following aspects: 1. Removal of causative factors: for example, if the patient’s condition is aggravated by not taking drugs regularly or accompanied by infection, the causative factors should be removed. If there is an infection, the first thing to do is to control the infection; 2. Symptomatic treatment: for the inflammation of the intestine itself, the treatment differs for different types of ulcerative colitis. For example, if the patient’s inflammation mainly involves the rectum and sigmoid colon, the degree may sometimes be mild and may be treated with enemas. However, if the inflammation involves a wide range of intestinal segments or is more severe, other treatments should be considered, such as long-term use of non-steroidal anti-inflammatory drugs, or even hormones in some patients, which may be used in different ways, preferring oral administration in mild cases and intravenous infusion in severe cases. Some patients have a heavy degree of inflammation, but also consider the use of immunosuppressants or infliximab and other drugs; 3, supportive treatment: ulcerative colitis patients need nutritional support therapy to maintain the stability of the internal environment, because patients have abdominal pain, diarrhea, mucopurulent stools and other symptoms, the nutritional status may be poor, need to strengthen the patient’s nutritional support, including giving intestinal probiotics to maintain a stable microecological environment in the intestine.
