Does kidney yang deficiency cause hypertension?

Kidney yang deficiency may cause hypertension.

Traditional Chinese medicine believes that the kidney is related to water metabolism and blood pressure regulation. If kidney yang deficiency occurs, due to kidney yang deficiency or dysfunction, the kidney's ability to regulate water metabolism and blood pressure decreases, which may lead to water retention in the body and increase blood volume, resulting in increased blood pressure. At the same time, kidney yang exuberance can maintain blood vessel tension, making blood circulation smooth. However, when suffering from kidney-yang deficiency, yang deficiency, vascular tension weakened, blood circulation may become poor, resulting in increased blood pressure.
