Kidney problems may be accompanied by hypertension.
The kidneys influence blood pressure by regulating the balance of sodium and water in the body. Under normal circumstances, the kidneys can adjust the excretion of sodium and water in urine according to the body's needs, thus maintaining stable blood pressure. However, when kidney function is impaired, as in conditions such as chronic kidney disease or glomerulonephritis, the kidneys' ability to regulate sodium and water decreases, leading to sodium and water retention in the body, increased blood volume, elevated vascular pressure, thereby triggering or worsening hypertension.
When kidney dysfunction is accompanied by hypertension, it is usually referred to as renal hypertension, a type of secondary hypertension. Renal parenchymal hypertension is mainly associated with parenchymal kidney diseases, such as acute glomerulonephritis, chronic glomerulonephritis, diabetic nephropathy, and chronic pyelonephritis. These conditions impair the kidneys' ability to manage water and sodium, leading to sodium and water retention and ultimately elevated blood pressure.
For patients with kidney disease, controlling blood pressure can prevent further deterioration of kidney function. In addition to managing blood pressure, patients should also take care to protect kidney function and avoid medications and foods harmful to the kidneys, such as nonsteroidal anti-inflammatory drugs and excessively salty foods.
If any physical discomfort occurs, prompt medical attention should be sought.
