Aldosteron

Aldosterone, abbreviated as Aldo, is a mineralocorticoid hormone produced by the adrenal glands. It plays a crucial role in regulating sodium and potassium balance, as well as blood pressure, by promoting sodium retention and potassium excretion in the kidneys. Researchers have found that aldosterone is part of the renin-angiotensin-aldosterone system (RAAS), which is critical for maintaining fluid balance and blood pressure homeostasis. Clinically, aldosterone levels are significant in diagnosing and managing conditions such as primary aldosteronism, Addison's disease, heart failure, and chronic kidney disease. Elevated aldosterone levels can lead to hypertension and cardiovascular damage, while low levels may indicate adrenal insufficiency. For athletes and biohackers, aldosterone's role in fluid and electrolyte balance is crucial, particularly in endurance sports where dehydration and electrolyte imbalances can impair performance. However, its relevance to longevity is less clear, though maintaining optimal levels may support cardiovascular health. Researchers observed that aldosterone levels can be influenced by factors such as posture, time of day, and dietary sodium intake, which can confound test results. Therefore, standardized testing conditions are recommended to ensure accurate assessment.
