Why are persons with high blood pressure advised to reduce the amount of salt in their diets?

Answer 1

The more sodium in your blood, the more blood volume increases because sodium attracts and retains water. As a result, the heart has to work harder to move the increased volume of blood through your blood vessels. This creates increased strain on the arteries and high blood pressure. Have you ever eaten a very salty meal and then been thirsty afterwards? That is the salt acting to increase your thirst. Then when you drink something, this fluid adds to the volume of blood inside the blood vessels. This increases blood pressure.

Answer 2

salt gives you high blood pressure because it increases hypertension which means 'clogging of vein's. because of the clogging it increases blood pressure.., as the blood has to squeeze though. leading to high blood pressure.

Answer 3

One thing salt does is raise blood pressure, which can happen with hypertension too. Salt just adds to the problem. There may be other reasons but that one is most obvious to me.

Answer 4

It helps to retain liquid in the body tissue causing higher blood pressure.
