Kidney is a clean blood in the human body [sewage factory]. The reason why kidney has sewage function, All by the diligent [workers] in the [factory]-nephron. Nephron consists of renal corpuscles and renal tubules. There are more than a million such workers in each kidney [factory]. The renal corpuscles can be further anatomically divided into glomeruli and renal capsules. Glomeruli are actually spherical tissues composed of many capillaries. In the process of blood filtration, it acts as a [sieve]. The renal capsules and tubules are the parts where urine is formed, concentrated and collected. It can be said that the kidney is our blood purification machine, but do you know, whether the kidney is good or not, blood pressure can also have the final say. How does hypertension damage the kidney? The damage of hypertension to blood vessels can be described as [meticulous], Kidney tissue is almost immune from hypertension. Hypertension mainly causes these damages to the kidney: Ischemia: After changes similar to sclerosis occur in renal arteries and small renal vessels, The lumen narrows, The kidney will be ischemic. Concentration function is impaired: On the basis of ischemia and hypoxia, Urine concentration is impaired, Patients’ friends often feel that the number of times they go to the toilet at night has increased inexplicably. Glomerular permeability increases: The glomeruli were also damaged, The filtering effect of [sieve] is getting worse and worse, Proteins, red blood cells and casts can appear in urine. The benefits of kidney [factory] become poor. The number of laid-off workers has gradually increased. As the number of nephron has gradually decreased, Kidney function is impaired, Eventually, renal failure can occur. In fact, The prevalence of hypertension in China is on the rise year by year, Renal dysfunction is becoming one of the major related diseases that affect the quality of life of friends of hypertension patients in China. The hard-working kidney is also suffering from [pain] caused by hypertension. Over time, It can cause damage to kidney function, And then affect all aspects of the body. With high blood pressure, How to prevent and treat kidney damage 1. The prevention and treatment of blood pressure hypertension kidney damage is still the focus of controlling hypertension itself. And the control requirements of blood pressure are stricter: Friends with hypertension accompanied by kidney damage or 24-hour urine protein greater than 1g, It is suggested that the blood pressure should be controlled below 125/75 mmHg, which is helpful to delay the damage of renal function. 2. Reducing proteinuria Because proteinuria level is closely related to the progression of renal damage, Therapeutic measures to reduce proteinuria have also attracted more and more attention. ACEI/ARb (angiotensin converting enzyme inhibitor/angiotensin receptor antagonist) has the efficacy of controlling blood pressure and reducing proteinuria at the same time. For the purpose of protecting kidney function, It is often the preferred choice when hypertension causes kidney damage. It is worth noting that, As ACEI/ARb can reduce creatinine clearance, In severe renal insufficiency (creatinine greater than 3 mg/dl), Not suitable for use. 3. Change bad living habits. For friends with mild to moderate renal insufficiency, We should strengthen the change of living habits. Strictly control the intake of sodium salt, Lose weight, Measures such as quitting smoking, controlling blood lipid and blood sugar, All require close attention. In addition, Carrying out a low protein diet under the guidance of doctors is also a key step to reduce proteinuria and prevent further damage to renal function. 4. Artificial dialysis If hypertension is left unchecked, Kidney damage develops to the final stage, It will enter end-stage renal disease, In other words, Kidney announced in advance [returning home from old age], No longer fulfill their [obligations]. Kidneys are [cleaners] that maintain the internal environment of the human body. Can remove waste and toxins from the body. With the progressive loss of kidney function, toxins in the body will accumulate, affecting the function of organs throughout the body. For friends of patients with end-stage renal disease, drugs are out of control, and doctors will recommend artificial dialysis, which uses artificial devices to filter harmful substances out of the blood on a regular basis.
