Why do you need to cut sodium when you have chronic kidney disease (CKD)?

ANSWER

Sodium is found naturally in many foods, but it's most common in table salt.

It affects your blood pressure and helps keep the water balance in your body steady. Healthy kidneys keep sodium levels in check, but if you have CKD, extra sodium and fluids build up in your body. This can cause a number of problems, like swollen ankles, high blood pressure, shortness of breath, and fluid buildup around your heart and lungs.
