Kidney deficiency usually does not directly cause hypertension, but can indirectly lead to high blood pressure. From a TCM perspective, the liver and kidney interact with each other. Kidney is the master of water in the body. If kidney water is insufficient, it will cause loss of oxygen to liver wood, and loss of oxygen to liver wood will cause liver fire, causing slow blood flow and insufficient supply to the liver, which will cause abnormal blood pressure and lead to clinical manifestations such as dizziness and headache. In addition to causing abnormal blood pressure, clinical manifestations such as mental fatigue, soreness and weakness of the waist and knees, or seminal emission, tinnitus, hair loss, loose teeth, thin and slightly red and dry tongue, usually with little moss, etc. When combined with kidney yang deficiency, patients may have manifestations such as coldness of the waist and knees. Therefore, Chinese herbal medicine can be used to regulate kidney deficiency, such as patients can take Chinese herbal medicines such as Liu Wei Di Huang Wan and Jin Kui Kidney Qi Wan under the guidance of a doctor, and can drink more water to increase blood flow in the body and improve blood circulation. Diet should be light, pay attention to low salt and low fat diet, try to eat less or no greasy barbecue food, quit smoking and limit alcohol. Improve living habits and increase activities appropriately to enhance physical fitness, which is helpful for the regulation of blood pressure.
