Three days after hernia surgery, it is necessary to decide on the diet of some foods, depending on the recovery of the function of its gastrointestinal tract. If the gastrointestinal peristalsis has not yet recovered and there is no gas or bowel movement, the diet should not be carried out at this time. If the peristalsis has just been restored for one day or so, a liquid diet is necessary, such as eating some milk, drinking protein powder, or making soup with pork, chicken or fish.
