After the third day, considering that the anastomosis has healed, it is recommended to start eating from a liquid or semi-liquid diet, that is, a semi-liquid diet such as rice soup, thin rice, chicken soup, or rib soup. After a week or so, the gastrointestinal tract is completely restored to normal, and basically, you can gradually transition to a normal diet, such as steamed buns, buns, rice and so on. In about 3 months after the surgery, the patient’s bowel movement has basically returned to normal and can return to the normal diet before, that is, can return to the normal diet before the surgery. If the patient is in the period of chemotherapy, there may be indigestion, nausea, vomiting and other symptoms, so it is important to eat foods that are easy to digest and absorb as much as possible during this time.
