Smoking before and after surgery: why quitting is your best ally for your health
Being told you need surgery—whether planned or urgent, cosmetic or life-saving—often triggers significant stress. For a smoker, this stress frequently leads to increased tobacco use. Yet medical science is unequivocal: smoking before and after surgery greatly increases the risk of serious complications.
Today, more and more surgeons make the success of their procedure conditional on completely stopping smoking several weeks before the big day. In this article, we will explore in depth why cigarettes are the number one enemy of your recovery after surgery and how to optimise your care pathway by quitting smoking.
The immediate physiological impact: the fight for oxygen
The first danger of cigarettes during surgery lies in oxygen transport in your blood.
Carbon monoxide: a silent poison
When you smoke, you inhale carbon monoxide (CO). This gas has an affinity for haemoglobin (the protein that carries oxygen) 200 times greater than oxygen itself. In other words, CO takes the place of oxygen in your red blood cells. For a smoking client about to undergo surgery, this means their organs and tissues are already in a state of under-oxygenation (hypoxia) even before the surgeon begins the operation.
The challenges of anaesthesia
The anaesthetist-intensivist must maintain perfect oxygenation of your vital organs while you are asleep. In a smoker, this task is more complex. The heart has to beat faster and blood pressure rises to compensate for the poor quality of the blood. In addition, tobacco irritates the bronchi and increases the production of secretions, which can cause respiratory complications (coughing, laryngeal spasms) after the operation, at the time of waking or extubation.
Healing: the risk of necrosis and wound dehiscence
Healing is undoubtedly the most critical issue for surgeons, particularly in plastic, cosmetic or orthopaedic surgery, when the client smokes
Nicotine-induced vasoconstriction
Nicotine is a powerful vasoconstrictor: it reduces the diameter of small blood vessels (capillaries). For a wound to heal, it needs a massive influx of fresh blood loaded with oxygen and nutrients. By smoking after the operation, you are literally cutting off the supply to your scar.
The visible consequences of tobacco on healing
- Delayed healing: A wound that should close in 10 days can take three weeks in a smoker.
- Wound dehiscence: The edges of the wound are not strong enough and the stitches can come apart.
Skin necrosis: This is tissue death. Due to a lack of blood caused by tobacco, the skin turns black and dies, sometimes requiring a second procedure to remove dead tissue or perform a graft.
A weakened immune system: the door left open to infections
Surgery creates a breach in your body’s natural barrier (the skin). The risk of hospital-acquired or post-operative wound infection due to tobacco is a major concern.
Less effective white blood cells
Tobacco toxins paralyse white blood cells, particularly macrophages and neutrophils, the “soldiers” responsible for destroying bacteria that try to enter wounds. In smokers, these cells are less mobile and less aggressive against pathogens.
Alarming statistics
Clinical studies show that smokers have a risk of surgical site infection 3 to 4 times higher than non-smokers. These infections are among the complications that can prolong hospitalisation, require heavy antibiotic treatments and, in some cases, compromise the final outcome of surgery (especially when an implant is placed).
Focus on orthopaedic surgery: tobacco and bones
If you are planning hip, knee or spine surgery, quitting smoking is even more crucial to avoid smoking-related complications.
Bone is living tissue that needs intense blood supply to repair itself. Nicotine inhibits osteoblasts, the cells responsible for creating bone tissue. The risk of non-union (failure of the bone to heal after a fracture or spinal fusion) is doubled in smokers. This can lead to persistent chronic pain and total failure of the procedure.
Pain management after surgery
A little-known fact about smoking and surgery: smokers feel pain more intensely after an operation.
- Nerve sensitisation: Chronic smoking appears to alter pain perception in the central nervous system.
- Use of painkillers: On average, smoking clients request higher doses of morphine or painkillers in the recovery room than non-smokers to achieve the same level of relief.
What is the ideal timeline for quitting smoking?
Quitting smoking is beneficial at any time, but some timeframes are more optimal than others for surgery:
- 6 to 8 weeks before surgery: This is the “gold standard” timeframe. It allows the immune system to regenerate and the lungs to regain effective self-cleaning function.
- 4 weeks before: Quitting one month beforehand significantly reduces the risk of healing complications.
- 24 hours before: At the very least, it eliminates all carbon monoxide from the blood, offering better safety during anaesthesia.
- After the operation: It is essential not to resume smoking for at least 4 weeks to give tissues time to strengthen. This is an opportunity to stop smoking altogether and quit smoking for good.
Why choose Reset Laser to quit smoking?
Preparing for surgery is a source of stress that makes quitting smoking through willpower alone very difficult. In addition, traditional nicotine replacement products (patches, gum) contain nicotine, which maintains vasoconstriction and impairs wound healing.
The Reset Laser smoking cessation method is the ideal alternative for clients awaiting a procedure:
- Zero nicotine: Our smoking cessation method stimulates your natural endorphins without introducing nicotine into your bloodstream, thereby protecting your blood vessels for optimal healing.
- A single session: We know time is sometimes limited before an operation. With our method to quit smoking, one hour is enough to address physical dependence on tobacco.
Peace of mind: By eliminating nicotine withdrawal, you approach your procedure with a calmer mind and a stronger body.
Give yourself the best possible chance for your operation
Your surgeon puts all their expertise at your service during the procedure. By quitting smoking, you become an active participant in your own recovery. Do not let a cigarette compromise months of preparation or the outcome of an important procedure.
