Kidney Disease: Understanding Fluids
Healthy kidneys balance the amount of fluid that enters and leaves the body. If your kidneys cannot maintain this fluid balance, you may need to limit your fluid intake. Always consult with your doctor and ask how many ounces of fluid you can have every 24 hours. The information below can be of help.

Make it a habit to measure fluids or check fluid content before you drink or eat.
