A person suffering from high blood pressure is advised to take minimum quantity ofcommon salt. Give reason.

Hello Student
Large amount of salt results in retardation of fluid. When amount of salt increase in our body , the amount of water also increases which further increases the blood pressure.

As the salt concentration in blood increases the water will move towards the blood cells and the volume of blood will increase. when the volume of the blood increases, so does the blood pressure. Heart does the extra work to pump the extravolume of blood . In this way extra salt in food enhance the blood pressure and it is risk for the heart as well.

Intake of large amount of salt decreases the size of blood vessel due to which heart pumps the blood with high pressure to give extra volume of blood and by this blood pressure increases

Osmotic pressure is directly proportional to the concentration of the solutes .Our body fluid contains a number of Solutes .On taking large amount of common salt , Na+Na+ and Cl−Cl− ions enter into the body filled thereby raising the concentration of the solutes .As a result osmotic pressure increases which may rupture the blood cells
