If you are on dialysis or are making less urine, you will likely need to limit your fluid intake.

If fluid builds up in your body, you can get puffiness (edema) in your legs and other parts of your body. This is uncomfortable and can sometimes cause pain. The extra fluid is also carried around in your bloodstream and pumped through your heart. If you gain too much fluid weight, it makes your heart work harder and can weaken your heart.

Dialysis can only take off so much fluid at a time and removing large amounts of fluid is very hard on your body. Your doctor or dietitian will tell you how much fluid you should be trying to keep to in a day. This is typically only 1 liter (4 cups) or 32 ounces daily, or 1.5 liters (6 cups) or 48 ounces daily if you are still making a good amount of urine.

Some foods have a lot of fluid in them. Foods that are liquid at room temperature (like ice cream, yogurt, popsicles, or Jello) also count as fluid. Some fruits contain a large amount of fluid as well.
