Aldosterone, an adrenal hormone, plays a pivotal role in maintaining sodium, potassium, and plasma volume. Produced in the adrenal cortex, its secretion is influenced by factors like sodium and potassium levels and the renin-angiotensin system.
While low aldosterone levels can result from high-sodium diets and conditions like Addison's disease, elevated levels might be associated with low-sodium diets, stress, and high blood pressure.
Primary hyperaldosteronism, a disorder where aldosterone production is unregulated, poses significant cardiovascular risks. Screening methods, including measuring serum aldosterone after sodium challenges, are crucial for diagnosis.
