Primary aldosteronism, also known as Conn syndrome, is a disorder characterized by the overproduction of aldosterone by the adrenal glands. Aldosterone is a hormone that regulates the body's balance of salt and water. The excess aldosterone in primary aldosteronism can lead to high blood pressure and low potassium levels. Some synonyms for primary aldosteronism include hyperaldosteronism, Conn's disease, aldosterone excess, and adrenal aldosteronism. These terms all refer to the same condition and are often used interchangeably in medical literature. Diagnosis and treatment of primary aldosteronism typically involve blood tests to measure aldosterone levels, imaging studies to locate any tumors or abnormalities in the adrenal glands, and medications to regulate aldosterone production and blood pressure.
