In primary hyperaldosteronism, which hormonal pattern is typically observed?

Explanation:
Primary hyperaldosteronism is caused by autonomous overproduction of aldosterone from the adrenal cortex. The excess aldosterone drives sodium reabsorption and volume expansion, leading to hypertension and hypokalemia. Because the blood pressure and volume are increased, the kidney senses this and suppresses renin release. So the classic pattern is high aldosterone with low renin (a high aldosterone-to-renin ratio). This helps distinguish it from secondary hyperaldosteronism, where both aldosterone and renin are elevated.
