It is not recommended to eat tofu milk within one month after total gastrectomy, but can be eaten if the diet gradually returns to normal after one month. After total gastrectomy, because the wound and anastomosis need some time to heal, so patients after total gastrectomy should start from fasting to fluid, semi-fluid diet gradually to soft food and then to the normal diet transition, generally one month after the resumption of a normal diet, at this time you can eat tofu milk. Tofu milk contains amino acids, unsaturated fatty acids, vitamin B12 and other nutrients, and patients after total gastrectomy can eat tofu milk appropriately; however, tofu milk is high in salt, and it is not recommended to eat a large amount of it, as high salt food will cause gastrointestinal stimulation, which is not conducive to the recovery of the disease. Patients after total gastrectomy should actively cooperate with the doctor’s treatment and have regular postoperative checkups.
