The earlier you quit, the greater your chances are of avoiding any surgery-related complications. It is especially important not to smoke on the day of your surgery. Fortunately, the body begins to heal within hours of quitting. Twelve hours after a person quits, his or her heart and lungs already begin to function better as nicotine and carbon monoxide levels drop. It takes less than a day for blood flow to improve, which reduces the likelihood of post-operative complications. We recommend that patients abstain from smoking for as long as possible before and after surgery, but even quitting for a brief period is still beneficial.
