Top Sydney Plastic Surgeon Dr Kernohan explains how Smoking and Nicotine Impacts Your Plastic Surgery Recovery and Results
- Are you a smoker and considering plastic surgery?
- Worried that smoking can influence the results of surgery?
- Interested how is the recovery period if you smoke?
Smoking is a lifestyle choice and is generally regarded as a bad habit. Numerous medical studies show that smoking is terrible for your health, and it is made apparent with the pictures on the cigarette boxes when you buy them.
Smoking when you think of undergoing plastic or cosmetic surgery is even worse as your body is going through physical trauma and needs every resource to heal and repair itself. But nicotine in the bloodstream interferes with that and can result in significant complications, which can give you a poor result from your cosmetic surgery procedure.

Why is Quitting Smoking Before Surgery Important?
Quitting before your surgery is important because that’s how you can ensure the best results from your surgery. There have been many pieces of research and studies performed on the effects of smoking on your body as it tries to heal from surgery. All of these studies have reached the same conclusion that smoking and surgery don’t go well together. The healing process is delayed, specific complications might occur and the recovery takes longer.
JAMA performed one such study, and it aimed to compare risks of complications after the surgery amongst smokers, former smokers, and nonsmokers. For former smokers, they selected only participants who had given up smoking at least a year before surgery. When comparing smokers and former smokers, it was found that 17 percent of the smokers were more likely to die post-surgery, and 53 percent of the smokers had a higher risk of developing major heart or lung issues.

Similarly, a meta-analysis was performed on other studies that focused the effects of smoking and surgery. The meta-analysis results showed that smoking affects different types of surgeries differently, but the end result almost always is necrosis and wound dehiscence. This is because nicotine decreases blood flow significantly, which can produce detrimental results in digit reimplantation during hand surgery. The success rate of digit or finger reimplantation in smokers compared to nonsmokers was found to be approximately 61 percent and 97 percent, respectively. This is a huge difference that needs to be taken into consideration, and it explains why quitting before surgery is a mandatory requirement.

4 Main Reasons to Quit Smoking before Surgery
There are three main reasons that will further make you consider quitting as they explain what happens to your body if you are a smoker and undergoing surgery.
1. Increased complications with anaesthesia
Your lungs have undergone significant changes and are harmed by your smoking habits. This makes the work of your anaesthesiology team even harder as they might have to work around the clock to make sure you are breathing while you are under the effects of the anaesthesia. To ensure proper breathing, your anaesthesiology team might need to use medications that will open up your lungs even more to allow more air to pass through, known as bronchodilators. The use of these medications along with anaesthesia can increase the risk of developing side effects associated with anaesthesia.
2. Increased stress on the heart
Smoking generally puts pressure on your heart and compromises its ability to function properly. The heart can become weak and will need to work even harder during the surgery and after the surgery to ensure proper blood flow to the rest of your body. However, nicotine in the bloodstream makes it difficult to do so. According to recent research, smokers have a higher risk of having a heart attack or other heart complications after surgery compared to nonsmokers. They have 77 percent higher chances of having a heart attack during the recovery period.
3. Risk of getting a blood clot
Smoking also affects the consistency of your blood, making it thicker than usual. This makes it easier for your blood to clot, which can get stuck in any blood vessel causing further complications.
4. Delayed wound-healing
As mentioned above, nicotine in your bloodstream will reduce the blood flow through your body. This in itself is harmful to your body, but when combined with the fact that there is an open incision that needs healing, which is mostly dependent on proper blood flow, the results can be disastrous.
Your tissues also need oxygen to heal properly. There is a higher concentration of carbon monoxide in your body if you smoke. This carbon monoxide reduces your tissue’s ability to receive enough oxygen. As a result it can further slow down the wound healing process, often resulting in wound dehiscence.
What Happens When You Quit Smoking
After your last cigarette, your body goes through changes to repair the effects of nicotine and tobacco on your body. Within eight hours, your blood pressure and heart rate will begin to return to normal, healing themselves. After twelve hours, the level of nicotine and carbon monoxide will reduce in your body. While it takes nicotine around one day to three days to be virtually untraceable in your bloodstream, its levels begin to gradually decrease within twelve hours of your last cigarette.
After a week of quitting smoking, your lung function will begin to improve. You will be able to clear out the mucus build up often seen in smokers. Your lung function will improve to the level of them being less reactive by the second week. This can help you breathe easier during the surgery. Three weeks after quitting, your body’s blood flow will improve significantly, hence, improving its ability to heal wounds.
