Whether or not you can fly after a recent surgery depends on the size of the surgery and the patient’s recovery. I. If the patient had a first-class surgery, such as body mass removal and abscess drainage. Since the surgery is less traumatic and the patient recovers faster after the surgery, it is possible to fly after the surgery. Second, if the patient has a smaller surgery, but the patient’s incision heals poorly after surgery. The incision is accompanied by redness, swelling, pain, local oozing and other manifestations, at this time, it is not recommended that the patient take the plane, and can take the plane after the wound is completely healed. Third, if the patient is doing a major surgery, such as radical treatment of malignant tumor of the stomach, internal fixation of femur fracture, resection of malignant tumor of liver, pancreatic and duodenal surgery, the patient often needs a longer time to recover in this case, and it is not recommended for the patient to fly in a short time to avoid the impact on the wound.
