Generally, after the gastrointestinal tract function recovers after the retraction surgery, about 2~3 days after the surgery, you can drink enteral nutrients, but the exact time varies from person to person. In the initial period after the retraction surgery, the gastrointestinal tract function has not recovered, and eating at this time will cause gastrointestinal discomfort, so we should wait until the gastrointestinal tract function recovers, i.e., after we start to defecate and pass stools, which will be about 2~3 days after the surgery, then we can eat liquid food. At this time, enteral nutrients can also be taken. And then slowly transition to semi-fluid food, and then to general food. Postoperative people can eat more high-quality protein, as well as fiber-rich fruits and vegetables, drink more water to facilitate defecation, pay attention to rest, maintain full of energy, in order to facilitate the recovery of the condition.
