Aldosterone is a hormone produced by the adrenal glands that plays a central role in regulating blood pressure by controlling sodium and potassium balance. Elevated aldosterone (hyperaldosteronism) is a treatable but often overlooked cause of resistant hypertension, while low levels can indicate adrenal insufficiency. This test is especially important for patients with high blood pressure that does not respond well to standard medications.
