Hyperaldosteronism is a condition where the body produces too much of the hormone aldosterone. This hormone helps regulate blood pressure by controlling sodium and potassium levels in the blood. When there is an excess of aldosterone, it can lead to high blood pressure and low potassium levels, which may cause symptoms like muscle weakness and fatigue. There are two main types of hyperaldosteronism: primary and secondary. Primary hyperaldosteronism is often caused by a benign tumor on the adrenal glands, while secondary hyperaldosteronism results from other conditions that affect the adrenal glands or the body's fluid balance. Diagnosis typically involves blood tests and imaging studies.
