Chronic colitis can be categorized into chronic specific colitis and chronic non-specific colitis. Chronic specific colitis can be restored through conditioning and auxiliary medication; chronic non-specific colitis is often incurable and can only improve symptoms and quality of life. 1. Chronic specific colitis: can be adjusted through the dietary structure, eating habits, emotions, exercise, etc., to strive for self-healing. (1) Dietary structure: Eat less stimulating or indigestible food, such as onion, radish, sweet potato, etc. (2) Eating habits: Eating should be chewed and swallowed slowly, eating too fast is not conducive to digestion and increases the burden on the gastrointestinal tract. (3) Emotional adjustment: Avoid anxiety, depression and other bad moods, when the mood is low, the digestive ability will also be significantly reduced. (4) Moderate exercise: moderate exercise can not only regulate the peristaltic rhythm of the gastrointestinal tract, but also improve physical fitness and enhance resistance to disease. 2. Chronic non-specific colitis: in addition to the above conditioning often need to follow the doctor’s orders to give mesalazine, methylprednisolone, probiotics and other medications, and a long drug cycle, the possibility of self-healing is not likely.
