Receiving insulin, glucagon, and glucose during and after surgery does not necessarily mean you have diabetes. In the context of open-heart surgery, particularly after an aortic dissection, these medications are typically used to manage blood glucose levels, support metabolic needs, and stabilize the body under surgical stress, regardless of a diabetes diagnosis.

Surgical stress can lead to stress-induced hyperglycemia (temporary high blood sugar), even in individuals without diabetes. This is common in major surgeries, where medications and procedures can affect insulin sensitivity and glucose regulation. Insulin may be administered to keep blood sugar within a controlled range, but this is usually a temporary measure. Peace.
