Primary and Secondary Hyperaldosteronism

Primary and secondary hyperaldosteronism is a disorder in which the adrenal glands produce an excessive amount of aldosterone, a hormone that regulates the balance of sodium, potassium, and fluids in the body. In the primary form the problem lies in the gland itself; in the secondary form it responds to another cause in the body.

Possible manifestations: high blood pressure that is difficult to control, muscle weakness, cramps, and increased thirst or urination.

Why it is investigated: it is one of the hormonal causes worth ruling out when blood pressure proves difficult to manage.

Who to see? Hyperaldosteronism is studied in endocrinology, the specialty that assesses the function of the glands and hormones. If your blood pressure is difficult to control despite follow-up, discussing it with the specialist can help identify the underlying cause.
