What effects do smoking/alcohol/drugs have on surgery?
The risks of complications from gastric sleeve surgery increase greatly if you smoke, drink alcohol or use recreational drugs. In particular, smoking will increase your risk of infection and delay the time it takes for your wounds to heal. Consequently, we strongly advise that you stop smoking and using all nicotine products for at least 6 weeks to 3 months before and after surgery to reduce the risk of complications. We also stress the importance of following your surgeon’s advice regarding smoking and the use of alcohol and recreational drugs.
