Why Does Patient With PKD Have High Blood PressureWhy does patient with PKD have high blood pressure? This may be a curiosity of many PKD patients.

High blood pressure is a common complication of PKD, and it can aggravate patient’s condition obviously in turn. Kidney cysts in patients who have high blood pressure will grow much faster than them in patients who do not have, so high blood pressure can cause PKD patient to have a worse prognosis.

Why does patient with PKD often have high blood pressure?

High blood pressure can be caused by two major reasons. One is the retention of sodium and water, and the other is the excretion of renin.

High blood pressure that is caused by the retention of sodium and water often appears in the late stage of kidney failure, which means patient’s kidneys can not filter the wastes and fluid adequately. As we know, PKD can progress gradually, and it will lead to kidney failure in the end, so this condition can also appear in PKD patient.

In fact, another reason of high blood pressure is more common for patient with PKD, because it may take more than ten years before PKD patient’s condition progresses into the late stage of kidney failure. But the time of hypertension appears in patient with PKD usually much earlier than this stage. Thereby, the excess excretion of renin is the reason for most PKD patients.

As we know, kidney has the function of excreting hormones, and renin is among them. For patient with PKD, the growth of kidney cysts in his kidney will oppress patient’s kidney structure, and that can cause the decrease of blood flow in patient’s kidneys, which will stimulate patient’s kidney to excrete renin, and after a series of reactions, the blood vessel will shrink, and patient’s blood flow will increase, which will lead to high blood pressure.
