We all need fluid every day to keep our bodies functioning properly. However, in heart failure extra fluid may build up in the body, making the heart have to work harder. Restricting fluid intake can help to limit this buildup of fluid in your body.

You should limit your fluid intake to 2 liters a day. 2 liters is equal to 64 fluid ounces, or eight 8-ounce glasses.

Anything that is liquid at room temperature counts as fluid.

Certain watery fruits and vegetables also count as fluids.

The following all count towards your daily 2-liter fluid limit:

  • ice cubes
  • soup
  • ice cream
  • sorbet
  • milkshake
  • popsicle
  • Fruits: watermelon, strawberries, grapefruit, and cantaloupe
  • Vegetables: cucumber, celery, and tomatoes

Your fluid restriction may leave you thirsty or with a dry mouth from time to time. These suggestions may help you feel more comfortable:

  • Rinse your mouth out with water. Spit the water out. Do not swallow.
  • Chill mouthwash and gargle for a fresh feeling.
  • Add a few drops of lemon juice to ice cubes or crushed ice and slowly let the ice melt in your mouth. Remember, 1 cup ice cubes = cup fluid.
  • Suck on hard candies or mints, or chew gum. Sugar free varieties may be more thirst quenching.
  • Suck on lemon or lime slices.
  • Eat frozen grapes or other frozen fruit.
