Question

Why salt affects blood pressure

Answer 1

Salt makes your body hold on to water. If you eat too much salt, the extra water stored in your body raises your blood pressure. So, the more salt you eat, the higher your blood pressure.

Answer 2

Salt affects kidney delicate balance of fluid and increases blood pressure.

Step-by-step explanation

Kidneys exclude the unwanted fluid from the body by filtering the blood. The sodium and potassium ions play their role to get extra water from the blood to urine collecting channels which then lead this water or fluid to the urinary bladder. So, eating the more salt increase these ions which wreck the delicate balance of filtration.

The more salts in the body also result in a higher blood pressure because of holding more water in the blood than the kidney filtrate channels.
