What is the typical fasting window for a healthy adult prior to surgery?

Explanation:
Reducing the risk of aspiration during anesthesia is the goal of preoperative fasting, so the stomach is empty when induction occurs. Solids take longer to empty than liquids, and a typical healthy adult is advised to abstain from solid food for about 6 to 12 hours before surgery. Some guidelines allow clear fluids up to around 2 hours before, but for the standard fasting window related to solid intake, 6–12 hours is the common recommendation. Shorter windows can leave stomach contents, while a full 24 hours is unnecessary and can cause dehydration or discomfort.
