If a patient has chronically elevated cortisol levels due to adrenal gland hyperactivity, which effect dominates over the long term?

A)Increased skeletal muscle mass
B)Enhanced immune system activity
C)Impaired glucose tolerance develops
D)Enhanced calcium absorption occurs

💡 Explanation

Chronically elevated cortisol results in impaired glucose tolerance because cortisol antagonizes insulin signaling, promoting gluconeogenesis and insulin resistance. Therefore, hyperglycemia is a likely outcome, rather than increased muscle mass or enhanced immunity, which are acute responses, or increased calcium absorption.
