What clinical finding is associated with the glucocorticoid effects of cortisol?

• A. Weight loss
• B. Increased muscle mass
• C. Increased sodium and water reabsorption
• D. Decreased blood pressure

Answer: (C)

Cortisol, a glucocorticoid hormone produced by the adrenal cortex, plays a significant role in various physiological processes, including metabolism, immune response, and fluid balance. One of the primary effects of cortisol is its influence on sodium and water reabsorption in the kidneys.

Cortisol acts on the distal tubules and collecting ducts of the nephron, promoting the reabsorption of sodium. This mechanism leads to an increase in sodium levels in the bloodstream. When sodium is reabsorbed, water follows osmotically, resulting in increased blood volume and, consequently, increased blood pressure. This is a critical adaptation for maintaining homeostasis during stress.

The other options presented don’t align with the well-documented physiological effects of cortisol. Weight loss is not typically associated with glucocorticoids; instead, prolonged exposure can lead to weight gain due to increased appetite and fat deposition. Increased muscle mass is contrary to the catabolic effects of cortisol, which can lead to muscle breakdown. Lastly, cortisol is associated with increased blood pressure rather than decreased blood pressure due to its effects on fluid retention and vasoconstriction.

In summary, the reabsorption of sodium and water by the kidneys, influenced by cortisol, explains why the choice
