Why do I need to restrict sodium in my diet?

We all need to consume some sodium every day to help our bodies function properly. But certain medical conditions, including heart failure, require a decreased intake of this nutrient.

Sodium can act like a sponge in our bodies, causing extra fluid to build up in the blood and body tissues. This extra fluid creates more work for the heart. It also can make symptoms such as high blood pressure and fluid buildup around the ankles and in the abdomen much worse.

A low sodium diet can help to decrease fluid buildup in the body.
