What are the causes of hypertensive nephropathy caused by hypertension? Blood pressure can cause kidney damage directly, that is called hypertensive nephropathy, including benign renal arteriolar sclerosis and malignant renal arteriolar sclerosis. The vast majority of hypertensive patients can have kidney changes, with age, glomerulosclerosis is also increased, about 15% of hypertension will develop into uremia.
In our country, the statistics of hypertension in 1998 were 110 million, and the rate of increase was 3 million 500 thousand people per year. By 2003, it was 127 million 500 thousand people, accounting for 10% of the total population. Every 3 families, or 10 people, has a high blood pressure, and there are about 600 million hypertensive patients around the world. That is to say, there are 10 hypertensive patients in 100 people, 1.5 people will become uremia, this is a terrible number, should arouse the whole society's vigilance.
What are the factors that affect hypertensive renal damage?
The incidence of hypertensive renal damage is positively related to the severity of hypertension and the duration of hypertension. Other possible factors include smoking, alcohol abuse, gender, ethnicity, diabetes, hyperlipidemia, and hyperuricemia, which influence each other and further exacerbate kidney damage. Men are more likely to suffer kidney damage than women. The age of onset of essential hypertension is generally 25~45 years, while hypertension is associated with kidney damage, and the age at which the symptoms are present is generally 40~60 years. The earliest symptom may be nocturia, which reflects an ischemic lesion in the renal tubules, and the concentrating function of urine begins to decrease. Proteinuria is then present, indicating that the glomerulus has undergone lesions. The degree of proteinuria is generally mild to moderate (+ or + +), 24 hour urinary protein quantitative is generally not more than 2 grams, but there is a minority of patients with massive proteinuria. Microscopic examination of the urine showed red blood cells and tubular types. Inpidual patients had transient gross hematuria due to rupture of the glomerular capillaries. Studies have shown that renal function in untreated hypertensive patients is significantly lower than in patients without hypertension.
Through the above introduction, we understand the causes of hypertension in hypertensive nephropathy, this is conducive to the formation of our better prevention of hypertensive nephropathy, and early treatment of hypertensive nephropathy. If you have any other questions, you can consult our online doctor or give us a message, we will reply to you as soon as possible.
