Low aldosterone in the presence of hypertension indicates that other causes of hypertension may still be present.
Hypertension is a common cardiovascular disease, mainly divided into primary hypertension and secondary hypertension, of which primary hypertension is more common, mainly caused by genetic factors, age and poor lifestyle and other factors.
Some secondary hypertension can be caused by elevated aldosterone, due to the fact that aldosterone has the ability to promote the body to retain sodium and water, thus causing water and sodium retention, the body’s circulating blood volume increases, and blood pressure rises accordingly. However, in addition to elevated aldosterone, pheochromocytoma, aortic insufficiency, sleep apnea syndrome and other diseases can cause secondary hypertension.
Pseudoaldosteronism (Liddle syndrome) needs to be further excluded, which can also cause hypertension, accompanied by hypokalemia, alkalosis and other symptoms, but blood and urine aldosterone levels are generally low.
Therefore, it is recommended to seek medical attention to identify the cause of hypertension and receive standardized treatment.
