Why You Should Be Smoke-Free for Surgery

  • IMAGE Your doctor has talked to you about surgery. Just the thought of it may cause you to feel stressed. If it is your habit to light up a cigarette during tense times, there are many reasons why you should kick the habit now—before your procedure.
  • Facing the Potential Risks

    Like many people facing surgery, you may really want to quit. Or, you may think that smoking will not cause a problem for the particular type of surgery that you need. However, no matter what type of surgery you are having, smoking can increase your risk of complications. A large number of studies have found that, compared to nonsmokers, smokers may have an increased risk of:
    • Respiratory and/or lung complications
    • Delays in wound and/or bone healing
    • Wound infection
    • A longer hospital stay (on a general, surgical, or intensive care ward)
    • Longer recovery time
    • Being sent to the intensive care unit (ICU)
    • Being readmitted to the hospital
    Delaying of wound healing is a major concern that doctors have about smoking. Nicotine triggers the blood vessels to become narrower, affecting blood flow. In addition, carbon monoxide, found in cigarette smoke, gets into the bloodstream, which means that there is less oxygen for the healing tissues. Just when your body needs more oxygen- and nutrient-rich blood, smoking acts as a barrier—blocking your body’s natural process to heal itself.
  • Zeroing in on Your Goal

    Keep your goal in mind: to have a successful surgery with very few complications. No matter if you need surgery on your gums, shoulder, or any other body part, quitting smoking may help you heal faster and have a better outcome. Just think—having fewer complications can translate into less pain, a quicker return to your usual routine, fewer trips to the doctor and pharmacy, and more money in your pocket.
    Even if your surgery is already scheduled, it is not too late to quit. While it is better to be smoke-free for months—rather than weeks—before surgery, making the decision to quit is an important one for your overall health. So if you are getting closer to the surgery date, use that as a reason to finally kick the habit.
    If you think that quitting so soon before your surgery will not make a difference, the American Cancer Society points out that your heart rate and blood pressure are reduced just 20 minutes after quitting. And within 12 hours, the level of carbon monoxide in your blood is also reduced. Two weeks to three months of being smoke-free can result in better circulation and improved lung function.
  • Starting the Process

    Do you feel inspired to quit, but do not know where to begin? There are so many smoking cessation options that you are sure to find one that fits your lifestyle. A great place to start the process is by making an appointment with your doctor. You will be able to get information about:
    • Nicotine replacement products, including patches, gum, and lozenges—While using one of these products is a much safer choice than smoking, you should still talk to your doctor about any potential risks nicotine may pose during or after surgery.
    • Nicotine inhalers or nasal sprays.
    • Prescription medications that can reduce the symptoms of nicotine withdrawal.
    • Smoking cessation classes and support groups.
    • Alternative methods, such as hypnosis or acupuncture.
    In order to be successful with your quit plan, you may need to combine strategies, like using a nicotine replacement product and joining a support group. Try different methods to reach your goal of being a nonsmoker. Also, visit websites like the and the , which provide a lot of smoking cessation resources. In addition, offers a “Step-by-Step Quit Guide.”
    Are you waiting for your surgery to be scheduled? Now would be a good time to talk to your doctor about your desire to quit smoking. The surgery may be postponed (especially if it is elective) to give you more time to be smoke-free.
