If you’re having general anesthesia, a physician anesthesiologist will give you medications that make you lose consciousness. After the surgery is complete, he or she will reverse the medication so that you regain consciousness — but you won’t be wide awake right away. You will probably be moved to a recovery room where your physician anesthesiologist will continue to monitor your breathing and heart function. Some people feel sleepy but otherwise fine as the anesthesia wears off; others have side effects such as nausea or chills, and sometimes vomiting. Your throat may be sore from a tube that helped you breathe during surgery. Recovery. After your operation, the anaesthetist will stop the anaesthetic and you'll gradually wake up. You'll usually be in a recovery room at first, before being transferred to a ward. Depending on your circumstances, you'll usually need to stay in hospital for a few hours to a few days after your operation.
