This refers to chronic colitis. The main symptoms of chronic colitis include abdominal pain, diarrhea or constipation, and mucus in the stools. Using a colonoscopy, one can observe the intestinal mucosa showing congestion, edema, or erosion, as well as white mucus adhering to the intestinal mucosa. With these observations, a diagnosis of chronic colitis can be made.

In terms of treatment, Western medicine primarily involves the oral administration of probiotics to regulate the intestinal flora. In Chinese medicine, treatment may involve herbal medicine taken orally based on differential diagnosis. Additionally, external treatments in Chinese medicine, such as moxibustion, enemas with Chinese medicine, or herbal hydrotherapy, can be used to treat the disease, and the treatment effects are good.
