How Aldosterone Affects Blood Pressure: Causes, Examination, and Treatment

Aldosterone is a hormone secreted by the adrenal gland and plays an important role in blood pressure regulation. It affects the processing of sodium and potassium by the kidneys, which in turn affects blood volume and blood pressure levels. Understanding how aldosterone affects blood pressure can help us better manage blood pressure health.

aldosterone on blood pressure and its mechanism

The main role of aldosterone is to protect sodium and potassium, increase blood volume, thereby raising blood pressure. When aldosterone levels are too high, the kidneys retain more sodium, causing blood volume to increase and the heart needs to pump harder, thereby raising blood pressure. Conversely, when aldosterone levels are too low, blood volume decreases and blood pressure may drop.

Aldosterone Abnormal Causes

Abnormal aldosterone levels may cause hypertension or hypotension. Hyperaldosteronism (such as primary aldosteronism) is caused by excessive secretion of aldosterone by the adrenal glands and may be associated with aldosteronoma or adrenal hyperplasia. Certain drugs (such as diuretics) may also affect aldosterone levels, causing abnormal blood pressure.

Aldosterone-related blood pressure problems

Checking aldosterone levels usually includes blood tests such as serum aldosterone concentration and plasma renin activity. Your doctor may recommend urine tests, electrolyte tests, and blood pressure monitoring. These tests help determine whether aldosterone levels are abnormal and find out what is causing blood pressure problems.

Treatment of abnormal aldosterone levels

Treatment of blood pressure problems caused by abnormal aldosterone levels usually requires comprehensive measures. In cases of hyperaldosterone, aldosterone antagonists or surgery (eg, adrenalectomy) may be needed. Aldosterone supplementation or adjustment of the use of other hormones may be necessary in cases of aldosterone hypo.

Lifestyle Adjustment

In addition to medication, lifestyle adjustments are also essential to control blood pressure. Limiting salt intake, maintaining proper potassium intake, exercising regularly and maintaining a healthy weight all help regulate blood pressure levels.

The effect of aldosterone on blood pressure cannot be ignored. By understanding its mechanism of action, testing methods and treatment methods, we can better manage blood pressure health and prevent the occurrence of related diseases.
