Secondary hyperaldosteronism is a condition where the adrenal glands produce excess aldosterone due to factors outside the adrenal glands. This often occurs in response to low blood flow to the kidneys, which can be caused by conditions like heart failure, liver cirrhosis, or renal artery stenosis. The increased aldosterone leads to sodium retention, potassium loss, and elevated blood pressure. The primary role of aldosterone is to regulate sodium and potassium levels in the body. In secondary hyperaldosteronism, the body's feedback mechanisms are disrupted, resulting in an overproduction of this hormone. Treatment typically focuses on addressing the underlying cause, which may involve medications or lifestyle changes to manage blood pressure and electrolyte balance.
