When you are on dialysis, fluid (water) may build up in your body between treatments. Too much fluid in your body can cause high blood pressure, swelling, trouble breathing and heart failure. Having extra fluid in your blood can also make your dialysis treatments more difficult. If you need to limit fluids, you will need to cut back on how much you drink. You may also need to cut back on some foods that contain a lot of water. Soups and foods that melt, such as ice, ice cream and gelatin, have a lot of water in them. Many fruits and vegetables are also high in water content. Talk to your dietitian about how much fluid you should have each day.

If you are limiting fluid and feel thirsty, try these tricks to quench your thirst:

  • Chew gum.
  • Rinse your mouth without swallowing. you can keep mouthwash in the refrigerator and use it as a cold rinse for your mouth.
  • Suck on a piece of ice, mints or hard candy (remember to count the ice as fluid, and pick sugar-free candy if you have diabetes).
  • Try sucking on a reusable ice cube. It feels cold, but doesn't add any fluid to your body.
