hiperaldoszteronizmusnál

Hyperaldosteronism, also known as hyperaldosteronism or Conn's syndrome, is a medical condition characterized by the overproduction of aldosterone, a hormone produced by the adrenal glands. Aldosterone plays a crucial role in regulating blood pressure and electrolyte balance by promoting sodium retention and potassium excretion in the kidneys.

The primary cause of hyperaldosteronism is typically a benign tumor in one of the adrenal glands (adenoma) or an enlargement of both adrenal glands (bilateral adrenal hyperplasia). Less commonly, it can be caused by adrenal cancer or a genetic predisposition. This excessive aldosterone leads to increased reabsorption of sodium and water, resulting in elevated blood volume and consequently, high blood pressure (hypertension). Simultaneously, the increased potassium excretion can lead to low potassium levels in the blood (hypokalemia).

Symptoms of hyperaldosteronism can vary but often include resistant hypertension that is difficult to control with standard medications, muscle weakness or cramps due to hypokalemia, fatigue, and headaches. In some cases, individuals may experience frequent urination or excessive thirst. Diagnosis involves blood tests to measure aldosterone and renin levels, as well as imaging studies like CT scans or MRIs to identify adrenal abnormalities. Treatment strategies depend on the underlying cause and may involve medication to manage blood pressure and potassium levels, or surgical removal of adrenal tumors.
