Which endocrine disorder is commonly associated with hypertension due to aldosterone overproduction?

• A. Cushing's syndrome
• B. Hyperthyroidism
• C. Primary hyperaldosteronism
• D. Addison's disease

Answer: (C)

Aldosterone overproduction drives sodium and water retention in the kidneys, expanding blood volume and raising blood pressure. In primary hyperaldosteronism, the adrenal cortex secrets too much aldosterone independently of renin, often from an adrenal adenoma or bilateral hyperplasia. This direct excess leads to sustained hypertension and often low potassium. The other conditions involve different mechanisms: Cushing's syndrome elevates blood pressure mainly through cortisol effects rather than excess aldosterone; hyperthyroidism can raise blood pressure via increased cardiac output but not due to aldosterone overproduction; Addison's disease causes adrenal insufficiency with low aldosterone, leading to low blood pressure rather than hypertension. Thus, the disorder associated with hypertension due to aldosterone overproduction is primary hyperaldosteronism.
