Some patients are able to eat fish after surgery for intestinal polyps, if the doctor allows the patient to eat after the surgery. Fish is low in fat and rich in protein, which can supplement the body’s lack of ingredients and help repair the wound. However, if the polyp is large and more polyps have been removed, it is necessary to abstain from eating water for a while and fish is not allowed to be eaten, so it is necessary to consult with the attending physician whether it is possible to eat fish or not. After the operation, patients should not drink alcohol, do not eat too spicy food, do not eat pickled food, etc., which are harmful to the healing of the wound. Vitamin-rich fruits, such as kiwi, apple, duck pear, etc., can be consumed appropriately. It is also necessary to eat well-digested food, such as noodles, porridge, soft bread, and so on.
