First of all, kidney disease patients easily combined with water excretion disorders, and then there will be edema, which is often said by doctors "water sodium retention"".

Second, the kidney itself has some effects on blood pressure, endocrine hormones, when there is kidney disease, these abnormal secretion of endocrine hormones, can cause high blood pressure. As we all know, hypertensive patients should be low-sodium, low-salt diet. Therefore, in order to better control the blood pressure in patients with kidney disease, low-salt diet is needed.

Finally, the kidneys have great flexibility in reabsorption of sodium and have a strong regulatory capacity. For patients with nephrotic syndrome, with the progress of the disease, the loss of effective nephron, the ability of the kidneys to regulate the balance of sodium decreased, if sodium intake hyponatremia can occur in severe cases, there may be muscle spasms, convulsions, or even Shock and coma. However, if too much sodium intake, can easily lead to water, sodium retention, edema and high blood pressure, and even induced heart failure.
