What is the harm that high salt does? Too much intake of salt can firstly
lead to the increase of high blood pressure(High Blood Pressure and Kidney Disease), which is also the greatest harm it
does. Water can combine with sodium easily, which leads to the retention of
water and sodium in the body. The blood vessels will swell, the wall of blood
vessels will become thinner and the barrier of blood vessels increases. At the
same time, the blood content increases, which gives more burden to the heart and
kidney, thus leading to further difficulties of discharging sodium and increased
high blood pressure.
When people are suffering from kidney disease, effective kidney nephrons
decrease, the concentrating capacity of convoluted tubules declines. In
addition, the discharge ability to sodium also decreases, which leads to the
excessive content of sodium in blood. If kidneys are not capable of discharging
the sodium in the blood, the organs such as kidney will be damaged, and what’s
worse, such damage is hard to recover. In addition, if the sodium in the body is
too high, it can also lead a large amount of potassium to discharge out together
with urine. Potassium plays an important role in adjusting the contract of
cardiac muscles. If a large amount of potassium is lost, the excitement of
cardiac muscles will decrease, which may even lead to the severe weakness of
cardiac muscles, and even lead to death to CKD and End Stage Renal Disease (ESRD) Refuse Dialysis Death?.
