Primary aldosteronism was first described in 1955 by American endocrinologist Jerome W. Conn after he examined a patient who exhibited hypertension due to an adrenal gland growth. Since then, scientists have learned more about this unusual condition, clinically known as Conn syndrome or hyperaldosteronism. While it is uncommon and affects only 0.1 and 20 percent of certain demographics, primary aldosteronism is a major trigger for some prevalent chronic conditions.


1. What Is Aldosterone?

Aldosterone is a hormone that helps the body regulate blood pressure. It is made in the adrenal glands and can increase sodium and potassium by sending a signal indicating how much of each the bloodstream or urine should release. Keeping these chemicals in balance maintains serum pH and electrolyte levels, which influences cardiovascular function.
