Hyperaldosteronism, also aldosteronism, is a
medical conditionwhere too much aldosteroneis produced by the adrenal glands, which can lead to lowered levels of potassiumin the blood.
*: Primary hyperaldosteronism, often caused by an adrenal cortical adenoma (a tumor), is also known as
*: Secondary hyperaldosteronism is due to overactivity of the
endocrinology, the terms "primary" and "secondary" are used to describe the abnormality (e.g. elevated aldosterone) in relation to the defect, i.e. the tumor's location. The adjective "primary" refers to an abnormality that directly leads to pathology, i.e. aldosteronism is caused by the apparatus that generates aldosterone. "Secondary" refers to an abnormality that indirectly results in pathology through a predictable physiologic pathway, i.e. a reninproducing tumor leads to increased aldosterone, as the body's aldosterone production is normally regulated by renin levels.
It can be
asymptomatic, but the following symptoms can be present
High blood pressure
