It is better not to eat rice, noodles, buns and indigestible food during the recovery period of intestinal obstruction. If the intestinal canal has been opened at the early stage of intestinal obstruction, and there is already exhaustion, no defecation and obvious pain, gastrointestinal decompression should be continuously performed at this time to correct water and electrolyte disorders and prevent the formation of abdominal infection after intestinal obstruction. In addition, the primary cause of secondary intestinal obstruction should be actively corrected and treated, and if necessary, surgery should be used to release the obstruction. During the recovery period of intestinal obstruction, fasting is required, and after fasting for a period of time, according to the patient’s recovery, the patient will slowly transition from liquid food to ordinary diet, and after transitioning to ordinary diet, do not eat indigestible and cold food, which are easy to form obstruction twice.
