I know to much salt can cause high blood pressure but how does it do that?

Answer 1

It can cause you to retain water.The increase in blood pressure can come from this subcutaneous water retention by putting excess pressure on the blood vessels and thus restricting blood flow.I'm sure that there are other physiological reasons but this would be one of the primary reasons.Water retetion can be prevented by drinking plenty of fluids therefore telling your body that it doesn't have to hold on to so much.I know that it sound backwards but it's true.Sodium also affects your electrolyte balance including potassium whichis vital for heart health.I'm sure this isn't the best answer that you'll get but just some info.

Answer 2

High blood pressure or hypertension is not caused by eating salt. Healthy adults cannot make changes in their pressure by adding or eliminating salt. However, if you do have high blood pressure reducing salt intake can help lower your pressure since salt can cause you to retain fluids. This is also true of aspirin. Unless you are prescribed an aspirin daily because it is indicated you do not need to take any to "help" your heart. Many times the causes of high blood pressure are unknown and a combination of treatments will lower it. By the way high blood pressure is not when the heart beats faster and a fast heart rate will not cause it.

Answer 3

It causes your body to retain fluids. It causes your heart to beat more as it pumps off the excess amount of fluids. Thus high bld pressure.
