Disease description:
Because I have hypertension, I went for a check-up recently. The test report stated that my aldosterone level was low. I would like to ask, is having a low aldosterone level good or bad?

Low aldosterone levels are usually not favorable. Aldosterone is an important hormone secreted by the adrenal glands that helps maintain extracellular fluid volume and circulatory system stability by promoting sodium retention and potassium excretion. When aldosterone levels decrease, the following issues may occur:
1. Hypokalemia: Reduced aldosterone levels can impair the renal tubules' reabsorption of sodium and water, leading to low blood potassium levels.
2. Hypertension: Aldosterone promotes sodium and water retention; reduced aldosterone levels may decrease sodium and water retention, potentially leading to elevated blood pressure.
3. Arrhythmias: Low aldosterone levels can also cause abnormalities in the heart's conduction system, resulting in cardiac arrhythmias.
In some cases, such as in patients with primary or secondary hyperaldosteronism,适度 lowering aldosterone levels may be beneficial as it can reduce sodium retention and the risk of hypertension, thereby improving related symptoms. However, such regulation should be performed under a physician's guidance using medications or other therapeutic approaches.
