How long should a patient ideally stop smoking before elective surgery?

Stopping smoking before elective surgery is crucial because it significantly reduces the risk of postoperative complications, such as impaired wound healing and increased respiratory issues. The ideal timeline for cessation is often suggested to be around 8 weeks prior to surgery. This duration allows the body to improve its oxygen levels and overall healing capacity, which is essential for any surgical procedure.

In practice, evidence shows that individuals who quit smoking for at least 8 weeks before surgery experience fewer complications compared to those who stop for shorter periods. While quitting for 4, 6, or even 10 weeks can offer benefits, the 8-week mark often strikes a balance between patient readiness for surgery and improving outcomes. For instance, stopping for only 4 or 6 weeks does not provide the same physiological advantages as 8 weeks. Conversely, while 10 weeks might be more beneficial, it might not always be feasible for patients facing an impending surgical deadline. Therefore, 8 weeks is commonly recognized as the optimal timeframe for encouraging better surgical outcomes.
