Typically, for patients who have had an ileostomy, they will pass gas about 2 days after surgery. After ileostomy surgery, usually, patients who recover quickly will start to pass gas in about 2 days, which also indicates that the bowel function is starting to recover. However, for patients who are in poor physical condition and are older, it will take longer for them to start passing gas after surgery. For patients after ileostomy, in daily life, also pay attention to rest, do not stay up all night and overwork. Also note that the diet should be light, eat more fiber-rich fruits and vegetables, eat more high-quality protein, drink more water, which is conducive to the recovery of the condition.
