Preoperative therapy refers to the treatment given to patients before undergoing a surgical procedure. This therapy is aimed at preparing the patient for surgery by reducing the risk of complications, improving outcomes, and optimizing recovery. Preoperative therapy can include a variety of interventions such as medications, physical therapy, nutrition counseling, and emotional support. The goals of preoperative therapy are to improve the patient's overall health, reduce pain and inflammation, and enhance the body's ability to heal after surgery. This approach has been shown to improve surgical outcomes and reduce the length of hospital stays.
