People suffering from kidney disease are often accompanied by hypertension. It is actually not very meaningful to distinguish between hypertension causing kidney damage or hypertension caused by kidney disease, and it is sometimes difficult to distinguish clinically because there is absolutely no impact on the treatment, and the treatment plan is the same. The main indicators that affect the prognosis of kidney disease are urine protein quantification and blood pressure. Therefore, if the renal function allows, all of them can be added with ACEI and ARB drugs, such as Irbesartan, Valsartan, Benazepril, etc. The goal is to control the blood pressure at 130/80mmHg and urine protein less than 0.5g, which can improve the renal prognosis. Paying attention to a low salt diet and consuming less than 6g of salt per day will have an unexpected effect.
