How does anaesthesia cause hyperglycaemia?

Answer 1

Anaesthesia can cause hyperglycaemia through various mechanisms, primarily by increasing stress hormones like cortisol and adrenaline, which raise blood glucose levels. Additionally, certain anesthetic agents can interfere with insulin secretion and action, leading to reduced glucose uptake by tissues. The physiological stress of surgery and the body's response to pain can further exacerbate this effect, contributing to elevated blood sugar levels during and after the procedure.
