Primary aldosteronism (al-DOS-tuh-ro-niz-um) is a type of hormonal disorder that leads to high blood pressure. Your adrenal glands produce a number of essential hormones. One of these is aldosterone, which balances sodium and potassium in your blood.
In primary aldosteronism, your adrenal glands produce too much aldosterone, causing you to lose potassium and retain sodium. The excess sodium in turn holds onto water, increasing your blood volume and blood pressure.
Diagnosis and treatment of primary aldosteronism are important because people with this form of high blood pressure have a higher risk of heart disease and stroke. Also, the high blood pressure associated with primary aldosteronism may be curable.
Options for people with primary aldosteronism include medications, lifestyle modifications and surgery.
