Enteritis is divided into acute enteritis and chronic enteritis. The main symptoms of acute enteritis include abdominal pain, diarrhea, fever, etc., and blood tests may show an increase in white blood cells and neutrophils. The treatment mainly focuses on anti-inflammatory drugs, hydration, and antidiarrheal therapies. Generally, recovery can be achieved within a week. The main symptoms of chronic enteritis include abdominal pain, diarrhea, or constipation. Colonoscopy can reveal changes in the intestinal mucosa such as hyperemia, edema, erosion, and mucus attachment, which can diagnose chronic enteritis. In terms of treatment, Western medicine primarily involves the oral administration of probiotics to adjust the gut microbiota. It can also be combined with traditional Chinese medicine based on syndrome differentiation. Integrating Chinese and Western medicine can enhance treatment effectiveness. Additionally, the diet should primarily consist of light and easily digestible foods.
