The main method of improving chronic colitis is symptomatic treatment. Chronic colitis is different from ulcerative colitis and radiation colitis. If there is no discomfort, no treatment is needed and lifestyle improvement is sufficient. If there is discomfort, symptomatic treatment will improve the symptoms. 1. Improve lifestyle and diet: Patients with chronic colitis should pay attention to their diet, eat more light and easy-to-digest food, and avoid cold and spicy food such as chili peppers and deep-fried food that is difficult to digest, so as not to aggravate the burden on the stomach and intestines. Patients should eat more fresh fruits and vegetables, quit smoking and drinking, and avoid staying up late and working hard. Strengthen exercise, enhance physical fitness, and maintain a happy mood. 2. Symptomatic treatment: (1) The cause of the disease should be identified before treatment. For example, if you have diarrhea, you need to do capsule gastroscopy or CT to rule out small intestine problems, CT to rule out pancreatic problems, blood sampling to rule out hyperthyroidism, viral infections, diabetes and other problems, and treatment of the original disease. (2) If all the tests are normal, then we need to consider the problem of poor intestinal function, the most common is irritable bowel syndrome, you can use antispasmodic drugs (pivotal ammonium bromide, etc.) and probiotics (bifidobacteria, etc.). It is also important to pay attention to diet and emotional regulation. For patients with chronic colitis, it is recommended to seek medical attention and receive professional treatment under the supervision of a physician.
