Ulcerative colitis causes both physical and psychological damage to the patient. When treating ulcerative colitis, it is important to not only eliminate the patient’s symptoms, but also treat the resulting comorbidities. The common hazards of ulcerative colitis are the following: 1. wasting, weakness, abdominal pain and diarrhea, and poor mood. 2. 2, ulcers of the oral mucosa, skin nodular erythema, hepatomegaly, arthritis, conjunctivitis, keratitis. 3.If ulcerative colitis persists for many years and spreads to multiple polyps in the whole colon, it will lead to hypoproteinemia or malnutrition anemia. 4, blood in the stool, intestinal obstruction, toxic intestinal dilatation or intestinal perforation, cancer. People are an organic whole, the lesion of any organ is not isolated, it has a close relationship with the balance of Yin and Yang of the whole body, the operation of Qi and blood, and the interconnection between the internal organs. We believe that gastrointestinal diseases are caused by the first deficiency of the spleen and stomach, and then dampness and heat accumulate inside and injure the blood channels, so that the abdomen is full, painful, and diarrhea with mucus and pus and blood stools, therefore, improving the lifting and lowering function of the spleen and stomach, expelling intestinal toxins, and repairing the damaged gastrointestinal mucosa are the keys to treatment.
