Hypertension is a very common disease, and hypertension can be very damaging to other organs, and we currently recognize that hypertension causes more damage to the heart, brain, and kidneys. The rate of control of hypertension has increased in the last 20 years due to the use of antihypertensive drugs, and the resulting incidence of heart damage and strokes has decreased significantly. However, the number of patients with hypertension causing kidney damage and eventually leading to chronic renal insufficiency is increasing year by year, and we should pay more attention to this type of disease in clinical practice. The kidney damage caused by hypertension develops gradually and is often not easily detected in the early stage. So the kidney damage of hypertension always comes quietly. How does hypertension cause kidney damage? (1) When hypertension occurs in the early stage, the kidney in order to protect it from the higher blood pressure to destroy the glomerulus and other organs, so the preglomerular artery protectively constricts the blood vessels to prevent the excessive blood pressure from passing into the glomerulus through the preglomerular artery, causing renal ischemic damage, which directly leads to changes in the structure of the renal blood vessels, glassy changes in the small renal arteries, fibrosis, sclerosis, lumen narrowing, and further development of focal Focal glomerulosclerosis. (2) As hypertension continues to develop, when blood pressure exceeds the renal threshold (160 mm Hg), the self-regulatory function of the kidney is deranged and the contraction of the anterior glomerular artery is inhibited, resulting in the “three highs” of glomerular hypertension, hyperperfusion and hyperfiltration, which directly damage the epithelial cells of the dirty glomerular layer and increase the permeability of the basement membrane, causing Proteinuria, which eventually leads to glomerulosclerosis. Moreover, the protein filtered from the glomerulus is absorbed in the proximal tubule through the action of cytokinesis, which can also cause interstitial inflammation and fibrosis of glomerular damage. What are the symptoms of kidney damage? Hypertension has kidney damage, mainly on the function of the renal tubules, so patients will have frequent nocturnal urination; because the glomerulus is damaged by hypertension, so the original protein that should not leak in the urine will appear in the urine, so there will be foam in the urine. We found some traces of hypertensive kidney damage, what should we do? The first thing to do is to control blood pressure, blood pressure lowering can reduce the damage to the kidney. But the choice of antihypertensive drugs is very important, it is necessary to pay attention to the adverse reactions and pharmacological metabolism of antihypertensive drugs. Different antihypertensive drugs block different aspects of blood pressure control in the human body, and the specific drug use must be formalized by a professional physician to identify the cause of hypertension, and according to the specific circumstances, the use of drugs to avoid the impact on the kidney treatment, but also according to the specific symptoms of the use of traditional Chinese medicine formula for conditioning, improve the overall state of yin and yang, so as to achieve both the symptoms and the root cause.
