Hyperaldosteronism is a condition characterized by the overproduction of the hormone aldosterone from the adrenal glands. This hormone helps regulate blood pressure by controlling sodium and potassium levels in the body. When too much aldosterone is present, it can lead to high blood pressure and low potassium levels, which may cause various health issues. There are two main types of hyperaldosteronism: primary and secondary. Primary hyperaldosteronism is often caused by an adrenal tumor or hyperplasia, while secondary hyperaldosteronism results from other conditions that stimulate aldosterone production, such as heart failure or kidney disease. Diagnosis typically involves blood tests and imaging studies.
