Sodium can significantly impact kidney function, especially for individuals with compromised kidneys. The kidneys regulate sodium levels in the body, but when they’re damaged, excess sodium can build up, leading to fluid retention, high blood pressure, and further kidney strain.
High sodium intake makes the kidneys work harder to filter the blood, which can exacerbate kidney damage and increase the risk of heart disease. Reducing sodium intake helps lessen the load on the kidneys, manage blood pressure, and prevent fluid buildup.
