In fact, hypertensive disorders and kidneys have a close relationship, and the two affect each other. The vicious cycle can lead to progressive deterioration of kidney function and finally develop into uremia. Many patients wait until hypertension obviously affects the heart, brain and kidneys before they find out, which makes many kidney disease patients go to the hospital only at an advanced stage, losing the best time for treatment. Therefore, controlling hypertension disease has a very important role in protecting kidney function. At present, it is considered that general hypertensive patients make their blood pressure control below 140/90mmHg, and if they are diabetic or already have kidney disease, they should make their blood pressure control within 130/80mmHg. For patients with urine protein quantification up to 1 g/day, their blood pressure control should be as much as possible below 125/75 mm Hg. For elderly patients, systolic blood pressure control is required below 150 mm Hg, and can be further reduced if tolerated. Effective control of hypertension can reduce the overall morbidity and mortality of cardiovascular and cerebrovascular diseases. Many patients will think, although I have high blood pressure, but no symptoms at all, so I do not take antihypertensive drugs. In fact, everyone tolerates hypertension differently, and it is not true that the higher the blood pressure, the worse the symptoms, but hypertension without symptoms can still produce damage to target organs such as the heart, brain and kidneys. Taking medication keeps blood pressure under control so that vital organs such as the heart, brain, and kidneys can be effectively protected. For kidney protection, blood pressure is the key. The first step is to bring down the blood pressure to the normal range before considering the protection of target organs. Good control of blood pressure itself is the best protection for target organs.
