Chronic colitis is a chronic, recurrent disease with colon, sigmoid colon and rectum as its attack sites. Refers to the inflammatory edema, ulcer and bleeding lesions of rectum and colon caused by various pathogenic reasons. The symptoms are pain in the left lower abdomen, diarrhea, acute diarrhea, watery stools, secret stools or diarrhea, sometimes good and sometimes bad, lingering and intermittent, and repeated attacks. Chronic colitis is a chronic colon, which is usually divided into specificity according to the cause of disease, that is, colitis with obvious causes and nonspecific colitis with unknown causes. What kind of diet should be paid attention to in the diet is introduced by our Xi 'an Jinghua Gastrointestinal Hospital. 1。 Besides avoiding catching cold and controlling emotions, diet is a very important aspect. During the attack period and remission period, you can't eat beans and bean products, wheat and flour products, as well as garlic, leek, potato, preserved eggs, cabbage, peanuts, melon seeds and other gas-producing foods. Because once eating, the gas in the gastrointestinal tract increases and the gastrointestinal motility is affected, which can induce the disease and even aggravate the symptoms. 2。 Persimmon, pomegranate and apple all contain tannic acid and pectin, which have astringent and antidiarrheal effects. Chronic colitis can be eaten in moderation. 3。 Patients with chronic colitis are mostly weak and have poor resistance, especially gastrointestinal tract infection, so they should pay more attention to food hygiene, and do not eat cold, hard and deteriorated food, prohibit alcohol and spicy spices. 4。 Patients with chronic colitis should also closely observe their adaptability to various foods and pay attention to individual differences. If diarrhea worsens after eating some foods that should not affect the intestines, we should find out the reasons, explore the rules, and try not to eat them in the future. 5。 Patients should usually strengthen exercise, such as playing Tai Ji Chuan, to strengthen the waist and kidney, and enhance physical fitness. 6。 Pay attention to keep your abdomen warm.
