Surgery cannot be performed for colds, which are mainly caused by bacterial or viral infections that lead to upper respiratory tract infections, when the body’s resistance and immunity are poor, and if surgery is performed at this time, it will lead to poorer body resistance, which will not help the body’s recovery, and the body itself has bacteria and viruses, which will more easily lead to more serious bacterial or viral infections after surgery. If the post-operative infection is serious, it may lead to systemic infection and the condition will be more serious, even leading to sepsis, etc., which seriously affects the life of the patient. In addition, when the body’s resistance is poor, the recovery of the incision after surgery is unfavorable, which can easily lead to infection at the wound. Therefore, once the symptoms of cold appear, you should first cure the cold symptoms through medication before surgery to ensure the safety of surgery and post-operative maintenance, during the cold period, you can drink more hot water, eat more vegetables and fruits to strengthen the body resistance to faster recovery.
