Which lab findings are expected in a patient diagnosed with Cushing's syndrome?

In a patient diagnosed with Cushing's syndrome, the expected lab findings include hyperglycemia and hypernatremia. Cushing's syndrome is characterized by prolonged exposure to elevated levels of cortisol, which can result in various metabolic disturbances.

Hyperglycemia occurs due to cortisol's role in glucose metabolism. Cortisol promotes gluconeogenesis (the production of glucose from non-carbohydrate sources) and decreases the sensitivity of tissues to insulin, leading to elevated blood glucose levels.

Hypernatremia can occur as a result of fluid retention, which is often seen in patients with Cushing's syndrome. Elevated cortisol levels can lead to increased reabsorption of sodium in the kidneys, contributing to higher sodium levels in the bloodstream.

These findings are key indicators of the syndrome and help in supporting the diagnosis, while also indicating the underlying pathophysiological processes associated with excess cortisol. This information is crucial for managing the patient's condition effectively.
