Hyperaldosteronism, also aldosteronism, is a medical condition where too much aldosterone is produced by the adrenal glands, which can lead to lowered levels of potassium in the blood.


*: Primary hyperaldosteronism, often caused by an adrenal cortical adenoma (a tumor), is also known as Conn's syndrome.

*: Secondary hyperaldosteronism is due to overactivity of the renin-angiotensin system.

In 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 renin producing 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

* Fatigue
* Headache
* High blood pressure
* Hypokalemia
* Intermittent or temporary paralysis
* Muscle spasms
* Muscle weakness
* Numbness
* Polyuria
* Polydipsia
* Tingling
* Hypernatraemia
* Metabolic alkalosis

ee also

* Hypoaldosteronism


Treatment includes Spironolactone,a K+ sparing diuretic that works by acting as an aldosterone antagonist
