After gastric surgery, you should pay attention to your diet and follow the doctor’s instructions to eat easily digestible and more nutritious food. Within a few days after gastric surgery, after the gastrointestinal tract is exhausted, it is recommended that fluids and semi-fluids are the mainstay of the diet, such as noodles, thin rice, etc., which is less burdensome on the stomach and intestines and is conducive to recovery. After being discharged from the hospital after gastric surgery, the following foods are recommended: foods rich in vitamins and fiber, such as fruits and vegetables; low-fat and low-cholesterol high-quality proteins, such as fish, shrimp and meat, protein powder, etc.; foods that help the gastrointestinal tract to digest, such as yogurt. However, attention should be paid to small meals and gradual progress. Other dietary considerations need to be consulted with the attending physician.
