What impact does carbohydrate intake before surgery have on protein catabolism?

Reducing protein catabolism before surgery through carbohydrate intake is beneficial because carbohydrates serve as an important energy source. When carbohydrate levels are adequate in the body, this helps preserve protein stores, as the body tends to utilize carbohydrates for energy instead of breaking down protein.

During fasting or caloric restriction, the body is more likely to catabolize protein for energy, which can result in muscle loss and negatively affect recovery post-surgery. Providing carbohydrates before surgery helps mitigate this by providing the necessary energy, thus preserving muscle mass and promoting better recovery outcomes.

This understanding is particularly important for surgical patients who are often in a state of stress and catabolism due to the surgical process itself. Therefore, ensuring they have adequate carbohydrate intake can lead to reduced protein breakdown, allowing for a healthier metabolic state leading into surgery.
