Hypertension or High Blood Pressure in Dialysis in Kidney Failure
Why is there hypertension or high blood pressure in dialysis in kidney failure patients? Hypertension or high blood pressure is a main complication in the treatment of dialysis, which often leads to heart failure and death. The statistics shows that before dialysis, about 80% to 100% uremia patients have had high blood pressure or hypertension. 87% diabetic kidney disease patients still can not control blood pressure after dialysis. Long time high blood pressure can really lead to threaten to patients.
Generally, high blood pressure or hypertension after dialysis can be divided into 2 kinds.
1. Capacity dependence high blood pressure, which usually takes place in the early stage of dialysis. Its main pathological mechanism is the retention of water and sodium, which makes the body weight increase the by 3% to 4%. There is edema, extending heart size and so on. In addition, there is also risk of heart failure. When body weight increases, blood pressure will increase accordingly.
2. Renin dependence high blood pressure, which takes place one hour after dialysis. Dialysis can lead to the decrease of body liquid, thus causing the further increase of renin activity, thus causing the deterioration of high blood pressure.
