John is scheduled to undergo surgery tomorrow morning to repair a torn ligament in his knee. He's been preparing for the procedure for weeks, but he's feeling a bit nervous about the fasting requirement he was instructed to follow before surgery. Why are patients like John advised not to eat or drink anything for at least 12 hours before undergoing surgery?
