Hypertension is the most common complication of kidney disease, especially in renal insufficiency, where almost 100% of patients suffer from increased blood pressure. Hypertension is not only a risk factor for the occurrence of cardiovascular diseases, but also leads to aggravation of kidney disease, increased urine protein, and accelerated deterioration of kidney function. The basis of hypertension treatment is to control the income of water and salt, the amount of salt should not exceed 6g (one beer bottle cap) per day. For patients with renal insufficiency, the water intake should be extraordinarily limited, and the effect of antihypertensive treatment is very poor in the case of excessive water load. The choice of drugs is preferred to the ACEI/ARB class, represented by Irbesartan, Valsartan, Benazepril, etc. This drug has the effect of reducing urinary protein and has a very good renal protective effect, but when creatinine exceeds 200umol/L, it is not recommended to continue until the start of dialysis can be applied again. If the blood pressure is poorly controlled, drugs of the CCB class, such as nifedipine extended-release tablets and amlodipine, can be added. Control blood pressure and slow down the deterioration of renal function through diet and medication.
