Initially the postoperative diet consists of liquid food, according to each person’s tolerance, new food and new textures are introduced until a normal diet is reached.  At all times the diet is compatible with the working life. The only necessary thing is to be able to stop a few minutes in order to take the number of prescribed meals.
