Why does secondary hypertension sometimes occur in patients with adrenal adenomas that overproduce aldosterone?

💡 Explanation

Secondary hypertension develops because aldosterone promotes sodium and water retention, increasing blood volume via mineralocorticoid receptor activation; therefore, arterial pressure rises due to the RAAS mechanism, rather than decreased sodium reabsorption or direct renin effects.
