Which metabolic complication is most commonly associated with parenteral nutrition?

Providing parenteral nutrition delivers a large, continuous glucose load directly into the bloodstream. That constant dextrose exposure often exceeds the body's insulin response, especially in patients who are stressed, critically ill, or receiving steroids or other insulin-antagonizing conditions. The result is hyperglycemia, which is by far the most common metabolic complication seen with PN. While other issues can occur—such as hypoglycemia if PN is interrupted, hyponatremia, or hypophosphatemia from refeeding in malnourished patients—these are less frequent overall. The key thing to monitor and manage is blood glucose, adjusting the dextrose concentration or PN rate and using insulin if needed to maintain glucose in a target range.
