This section covers three key pre-surgery requirements. First, patients must quit smoking at least 4 weeks before surgery due to its negative impact on wound healing and surgical outcomes. Second, alcohol should be avoided 10-14 days before and after surgery, with strict limits if abstaining isn't possible. Third, physical fitness is crucial - even light exercise like 20-minute walks can significantly improve surgical outcomes and reduce complications like pneumonia and infections. The section concludes by mentioning pre-operative screening tests for conditions like anemia and vitamin deficiencies.
