First, the kidneys serve the important task of regulating blood pressure 1, the ability of the kidneys to mediate water and sodium will affect blood pressure The kidneys have the function of regulating water and sodium in the body, once kidney function is impaired, the water and sodium that cannot be discharged will be retained in the body, resulting in increased vascular pressure and increased blood pressure. Therefore, kidney disease is an important cause of hypertension. 2, the kidneys secrete hormones to adjust blood pressure The kidneys are also an important endocrine organ, which can secrete renin and vasotocin to regulate the body’s blood pressure. If the kidneys are damaged, the hormones that regulate blood pressure in the body will also be out of balance, making the blood vessels tense and increasing vascular tone, leading to high blood pressure. Second, hypertension can also cause kidney disease What is hypertension? Hypertension occurs when the systolic blood pressure is above 140 mmHg and the diastolic blood pressure is above 90 mmHg. If the state of hypertension continues, the walls of blood vessels are constantly under strong pressure, and the blood vessels will be damaged and evolve into atherosclerosis. Because of arteriosclerosis, the blood flow is not smooth and the blood flow to the kidneys will be reduced, leading to kidney lesions or accelerating both damage. In addition, hypertension can become an accelerating factor for other diseases causing nephropathy, such as diabetic nephropathy. Third, kidney disease and high blood pressure are the culprits of each other. It can be seen that kidney and blood pressure affect each other. Once the blood pressure rises, it will affect the kidney function; conversely, when the kidney is bad, it will also have an impact on the blood pressure. It is common to see kidney disease and hypertension occurring together in clinical practice. Whether it is to prevent hypertension from damaging the kidneys or kidney disease from triggering hypertension, the most important thing is to maintain a stable blood pressure and keep it below 130/80 mmHg as much as possible to effectively protect the kidneys and reduce the occurrence of cardiovascular complications.
