1, sodium excretion disorder
Sodium excretion disorder is the main cause of high blood pressure, because the kidney dominates the discharge of excess substances and wastes in the body. If these substances cannot be excreted normally, it means that there is something wrong with the kidney. Among them, sodium ion will increase obviously, which will affect blood pressure and make blood pressure rise gradually. Usually, people with heavy taste in eating habits, or people who damage their kidneys because of taking drugs, are prone to renal hypertension due to sodium excretion disorder.
2. Sympathetic nerve excitation
Sympathetic nerve excitation will affect the endocrine system of the body, so kidney disease leads to sympathetic nerve excitation, which is easy to raise blood pressure. When there is a problem with renal function, it will affect the local endocrine system, especially the kidney needs to secrete more hormones, which will affect the sympathetic nerve of the human body, the most obvious of which is adrenal hormone. While the sympathetic nerve remains excited, it will gradually raise blood pressure.
3. Renin activation
This situation is mainly because a hormone is activated and secreted in large quantities, which leads to vasoconstriction. This process will promote the reabsorption of sodium and release aldosterone, but it will aggravate the symptoms of renal water and sodium retention and easily lead to hypertension. This is a symptom of dysfunction caused by the influence of renal function, which often appears in more serious nephropathy.
4. Renal artery stenosis
If the more serious nephropathy develops to the later stage, it will cause the problem of renal artery stenosis, which will lead to a significant increase in local blood pressure and affect the blood circulation of the kidney. This situation is easy to form a vicious circle, because after the blood pressure increases obviously, the local qi and blood are not smooth, which will lead to the aggravation of renal function damage, and after the renal function is missing, it will lead to the further increase of blood pressure, so it is difficult to cure.
5. Renal parenchymal lesions
Renal parenchymal lesion is an acute lesion in renal parenchymal tissue. Because blood needs to circulate throughout the body, naturally including the kidneys. When renal parenchyma changes, it will cause local blood circulation disorder. If the problem of blood circulation disorder exists for a long time, the blood pressure will gradually increase, which is not obvious in the early stage and will continue to develop with the aggravation of renal parenchymal lesions.
6. Direct vascular disease
Kidney diseases can cause vascular diseases, because when the kidney has problems, the reabsorption function of the kidney will be affected, especially the filtration rate of renal tubules and glomeruli will decrease, and a large amount of toxins will be deposited in the blood. These toxins are likely to cause direct pathological changes of blood vessels, which will not only cause damage, but also lead to arteriosclerosis, which will also lead to high blood pressure.
Renal hypertension is usually secondary hypertension. As long as we can control nephropathy, we can alleviate the symptoms of hypertension and avoid the harm caused by hypertension. However, once hypertension is found, it needs to be treated in time, otherwise it may turn into primary hypertension, which will not only control blood pressure, but also aggravate kidney disease.
