What is a benefit of consuming oral nutrition with carbohydrates up to 2 hours before bariatric surgery?

Consuming oral nutrition containing carbohydrates up to 2 hours before bariatric surgery offers the beneficial effect of decreased insulin resistance. This phenomenon is especially relevant in the context of preoperative care, where the immediate goal is to optimize the patient's metabolic status prior to the surgical procedure.

Carbohydrate loading can lead to improved glucose metabolism, resulting in less inflammatory response during the perioperative period and enhancing overall insulin sensitivity. By mitigating insulin resistance, the patient's body is more capable of managing blood sugar levels, which can significantly aid in recovery and potentially reduce the risk of hyperglycemic complications during and after surgery.

In addition to the metabolic advantages, carbohydrate intake before surgery can also help minimize the physiological stress associated with surgery, contributing to a smoother transition during the fasting period and reducing the likelihood of postoperative complications linked to severe metabolic stress.
