The Hormone That Balances Your Electrolytes
Understanding Aldosterone and Its Functions
Aldosterone is a vital hormone produced by the adrenal glands, specifically in the outer layer called the adrenal cortex. It plays a central role in regulating blood pressure and maintaining the balance of electrolytes in the body. Classified as a mineralocorticoid, aldosterone is essential for sodium conservation, potassium excretion, and water retention, all of which are critical for healthy cardiovascular function.
Key Functions of Aldosterone
Aldosterone works by signaling the kidneys to retain sodium and water, which helps increase blood volume and pressure. Simultaneously, it prompts the excretion of potassium to maintain a proper balance of electrolytes. This mechanism ensures the stability of blood pressure, hydration levels, and overall fluid balance in the body.
The Role of Aldosterone in Health and Disease
Imbalances in aldosterone levels can lead to significant health issues. Overproduction of aldosterone, known as hyperaldosteronism, can cause high blood pressure and low potassium levels. Conversely, insufficient aldosterone production, termed hypoaldosteronism, may result in dangerously low blood pressure and elevated potassium levels. Both conditions can have severe consequences if left untreated. Disorders Linked to Aldosterone Imbalance Disorders related to aldosterone imbalance include primary aldosteronism (Conn’s syndrome), often caused by adrenal gland abnormalities, and secondary aldosteronism, which may result from other health conditions like kidney disease. Addressing these disorders requires accurate diagnosis and targeted treatment to restore balance.

FAQs About Aldosterone
1. What is the normal range of aldosterone in the blood?
The normal range for aldosterone levels varies but is typically between 4–31 ng/dL for adults when measured in a sitting position.
2. How are aldosterone levels tested?
Aldosterone levels are measured using a blood or urine test, often paired with a renin activity test to calculate the aldosterone-to-renin ratio (ARR), which is key for diagnosing certain conditions.
3. What are the symptoms of high aldosterone (hyperaldosteronism)?
Symptoms include high blood pressure, fatigue, muscle weakness, frequent urination, and low potassium levels (hypokalemia).
4. What causes high aldosterone levels?
Common causes include adrenal gland tumors, adrenal hyperplasia, or chronic kidney disease.
5. What are the symptoms of low aldosterone (hypoaldosteronism)?
Symptoms may include low blood pressure, dizziness, fatigue, and high potassium levels (hyperkalemia).
6. Can aldosterone imbalance be treated?
Yes, treatments include medications like aldosterone antagonists (e.g., spironolactone), dietary adjustments, and addressing underlying conditions.
7. How does aldosterone affect blood pressure?
Aldosterone increases sodium and water retention in the kidneys, leading to higher blood volume and blood pressure.
8. Are there natural ways to balance aldosterone levels?
Managing stress, maintaining hydration, and a diet with balanced sodium and potassium can support healthy aldosterone function.
9. Can aldosterone disorders be hereditary?
Yes, conditions like familial hyperaldosteronism have a genetic component, increasing the risk in certain families.
10. When should I consult a doctor about aldosterone issues?
If you experience persistent high blood pressure, muscle cramps, fatigue, or frequent dizziness, consult Dr. Zaar, the best endocrinologist, for personalized care.
