Patients with chronic colitis should stay away from irritating foods, such as chili, alcohol, durian, and horseradish, which can lead to congestion and edema of the intestinal mucosa, followed by dilatation of the intestinal canal and accelerated peristalsis, and the patient may experience significant abdominal pain and bloating. In addition, you should stay away from dry or sticky foods, such as rice cakes and mixed grains. You should also pay attention to fresh vegetables or fruits and other vitamin-rich foods, and take appropriate physical exercise. Recurrent chronic colitis also requires systemic medication, most commonly oral azathioprine and salazosulfapyridine. During treatment, changes in internal environmental indicators should also be monitored. Prolonged diarrhea also tends to lead to ionic disturbances and acid-base imbalances, so prevention should also be observed.
