Sodium is an important electrolyte present in the body. Sodium also helps the following functions in the body:

– Regulation of blood pressure and blood volume

– Helps to transmit impulses for nerve function and muscle contraction

– Regulates the acid-base balance of the blood and body fluids

Although sodium is necessary for body functions, consuming too much sodium can be harmful for the body especially for people with kidney disease since the kidneys are not able to filter the excess sodium from the body. This causes the sodium to build up in the body. Excess sodium in the body can cause the following:

– High Blood Pressure

– Edema (swelling in the legs, hands and face)

– Shortness of breath

– Stress on the heart which can lead to heart failure

People with kidney disease should therefore, restrict the amount of sodium in their food. Common salt used in the food is a major source of Sodium in the food.

Please ask your dietician how much sodium you are allowed to have per day.

Gradually reduce the amount of salt in your food. Slowly you will find it difficult to eat food with normal salt.

Beware of Low Sodium salts. They contain Potassium!!
