how is sodium chloride in the body linked with blood pressure?

Answer 1

Sodium chloride is the chemical name for good old table salt. In the bloodstream, when the blood has a higher concentration of salt, the kidneys will try to conserve plain water to keep the blood from getting too concentrated. The effect of this is to make the volume of blood in the blood vessel larger, and this larger volume will put more pressure on the walls of the blood vessels - resulting in high blood pressure.
The kidneys are very efficient in conserving water and salt, so we humans really only need about a teaspoon to a teaspoon and a half of salt in the diet per day; the average American diet contains 3-5 teaspoons of salt.
So, if a person has high blood pressure, the doctor will often recommend lowering the amount of salt in the diet.

Answer 2

Sodium Chloride (table salt) is Hygroscopic. That means it absorbs water. Think of a salt shaker on a picnic table on a rainy or humid day. The openings clog up with wet salt. Salt in the blood acts the same way. It absorbs water. This extra water in your blood makes it harder for the heart to pump causing high blood pressure.

Answer 3

Blood pressure is affected by blood volume. When you consume salty foods with lots of sodium this ends up in your blood. The sodium attracts water to your circulation, causing increased blood volume therefore increased blood pressure.

Answer 4

more sodium chloride = higher bp is all i can tell you
