Why do you fast prior to general anaesthesia?

Fasting prior to general anaesthesia is crucial to reduce the risk of aspiration, where stomach contents can enter the lungs during surgery. An empty stomach minimizes the likelihood of regurgitation and potential complications, such as pneumonia. Additionally, fasting helps ensure that the medications used during anaesthesia are more effective and that the patient is in a safer condition for the procedure. Typically, patients are advised to refrain from eating or drinking for a specified period before their operation.
