Common Sense of Hypertensive Nephropathy

What are causes of Hypertensive Nephropathy?

Primary Hypertension causes benign arteriolar nephrosclerosis and malignant arteriolar nephrosclerosis. Then, Hypertensive Nephropathy will appear.

What are symptoms of Hypertensive Nephropathy?

Hypertensive Nephropathy usually attacks patients who has been accompanied with Hypertension for more than 5~10 years, most of whom are at the stage of 40~50 years. In early stage, symptoms are characterized with increased enuresis nocturna and proteinuria, except some special cases, such as transience gross hematuria caused by the fracture of blood capillary, slight lumbago, left ventricular hypertrophy, heart failure, cerebral arteriosclerosis and (or) cerebrovascular accident. The course of disease develops slowly. Some of them develop into renal failure，but most of them lead to slight damage of kidney or abnormal urinary routine test. Patients with accelerated hypertension, whose diastolic pressure is more than 16Kpz (120mmHg), are accompanied with cardio-cerebrovascular complications which will lead to the increase of proteinuria and hematuresis, causing the decline of renal function.

What should patients with Hypertensive Nephropathy pay attention to? If proper, to a great extent, the diet is an important factor for the prevention of disease progression.

First, Diet changes: under the guidance of doctor, patients should analyze their diet and refuse some tempting food, forming a good habit of diet so as to meet the requirement of nutrition, which will improve the life quality.

Second, the supply of calorie should be limited: suitable intake of calorie should be based on patients’ condition which takes the maintenance of ideal weight as a standard. Because of lipid disorders, patients with Hypertensive Nephropathy should reduce the intake of fat, controlling calorie better with the improvement of metabolic disturbance.

Third, diet with low salt and high vitamin: the intake of salt is limited. Therefore, the food with preservative just can be eaten a little, except pickled food, which is forbidden completely. By contrast, the intake of vitamin, especially vitamin B, should be abundant, which is beneficial to the adjustment of metabolism in body. If it is necessary, vitamin supplements can be taken.


Four, protein is the necessary nutrient for human body. But, too much intake of protein will increase the burden of kidney. In other word, if the intake of protein is insufficient, the supply of nutrition will be affected. Thereby, the intake of protein should be based on the condition of renal function: without obvious damage of renal function, the intake of protein is limited to 50g/d; if the creatinine and urea nitrogen are obviously abnormal, the intake of protein should be reduced to 20g~40g/d.
