Post sleeve gastrectomy, for how long should a patient remain NPO?

Three hours
Six hours
Twelve hours
Twenty-four hours

The correct answer is: Six hours

After sleeve gastrectomy, patients are advised to remain NPO (nothing by mouth) for a specified duration to allow for recovery and minimize complications. The typical recommendation of six hours is based on the need to ensure that the gastro-intestinal tract is sufficiently healed from the anesthetic effects and initial surgical trauma. During this time, the patient's body can stabilize post-anesthesia, which helps reduce the risk of complications, including aspiration. This duration also allows any residual effects of the surgery to diminish before introducing oral intake, reducing the likelihood of nausea and vomiting. In postoperative care, specific practices may vary based on the individual surgeon's protocol and the patient's condition; however, six hours is a widely accepted timeframe for most individuals undergoing sleeve gastrectomy.
