Alcohol has far-reaching effects on the body. It can weaken your body's ability to tolerate surgery; it can also hurt your recovery. Taking a break from alcohol for just a few weeks before surgery can increase your safety.
Alcohol weakens your body's ability to tolerate surgery. It just takes a few weeks of abstinence to normalize, similar to marijuana.
What are the effects of alcohol before surgery?
Even though ethanol was used in ancient times for anesthesia, it was very dangerous. Alcohol affects the body from head to toe:
When should I stop drinking alcohol before surgery?
The negative health effects of alcohol depend on how heavy your drinking is. For example, drinking 3-4 drinks a day has a 50% increased risk for the side effects listed above. This level of drinking includes 7-49% of the population. Unfortunately, heavier drinking (5+ drinks a day) increases risk by 200-400%.
The heavier the alcohol load, the longer you should consider abstaining before surgery. You need to give your body time to recover from the effects of alcohol.
Stopping alcohol 3-8 weeks before surgery can help your body recover to normal.
Big rewards for your surgical recovery
Preparing for surgery is powerful. Just like preparing to give a speech, the more energy you invest before surgery, the healthier your outcome. Reducing alcohol consumption can make your recovery safer. Moreover, it can also improve your health in the long run.
Alcohol can have serious complications after your operation, too. See my article on alcohol after surgery for an even safer recovery.
As always, discuss your habits with your anesthesiologist before surgery. This will ensure the safest, and most comfortable, experience for you.
