Because the stomach has been removed, the patient’s food intake is affected in the short term. At the beginning, the recovery diet should be less and more meals, mainly liquid food or semi-liquid food, such as thin rice, noodles, rice soup or chicken soup, fish soup, rib soup, etc. When the patient further recovers, he can gradually transition to soft food, and can increase the amount of food, you can eat soft rice, pasta, including lean meat can be eaten, and it is also recommended to eat more fresh vegetables and fruits to supplement vitamins.
