No, alcohol should be avoided before surgery. One source says to stop drinking at least 4 weeks before the operation. Another says not to drink alcohol in the days and weeks before surgery, and one set of fasting rules says no alcohol for 24 hours before surgery. Alcohol can make anesthesia less predictable, slow healing, and raise the risk of problems like blood loss or withdrawal if you drink regularly. If you drink often, tell your anesthetist and nurses so they can plan for you. Verify the exact plan with your surgical or anesthesia team in case they want something different for you.
