Watching your fluid intake when you have heart failure
IntroductionToo much fluid in your body can make it harder for your already-weakened heart to pump. Your doctor may prescribe a diuretic to help get rid of excess fluid. He or she may also suggest that you limit liquids so that your body can get rid of the extra water and sodium. Key points
Return to topic: How much fluid should I have?Fluid usually is not restricted in heart failure unless you have advanced or severe heart failure. Usually, restricting sodium intake alone is enough to help your body get rid of extra fluids. However, if your doctor recommends that you limit the amount of fluids you drink and eat (fluid intake), you will need to keep track of all beverages and any foods that contain a lot of liquid. Your doctor will tell you how much fluid you can have in a day.

Continue to How can I be sure that I am getting enough fluid?Your doctor will tell you how much fluid you should be taking in every day. Recommendations may range from about 1500 mL (1.6 qt) to 2000 mL (2 qt), or about 48 fl oz (1420 mL) to 64 fl oz (1893 mL) per day. Here are the amounts of fluid in some common equivalent household measures:
It is important to know how much fluid your regular drinking glasses hold. You can find out by filling your drinking glass with water and then measuring the amount in a measuring cup. Once you know this, you won't have to measure every time. Besides water, milk, juices, and other beverages, some foods contain a lot of fluid. Any foods that will melt (such as ice cream, gelatin, or flavored ice treats) or foods that have a lot of liquid (such as soup) should also be measured and counted as part of your fluid intake. How to keep track of your fluid intake One method for keeping track of your fluid intake is to have an empty container that holds the amount of fluid you are allowed for the day. As you drink fluids, put an equal amount of water into the container until you reach your fluid limit. When the container is full, you have reached your fluid limit and should stop drinking. Another method for keeping track of your fluid intake is to allow yourself 8 fl oz (1 cup) of fluid at each meal [3 x 8 fl oz = 24 fl oz, or 3 cups]. You can then fill a container with water to keep in your refrigerator that contains the balance of your fluid allowance. For example, if you are allowed 48 fl oz (6 cups) of fluid a day, you could have 24 fl oz (3 cups) divided into three meals and then another 24 fl oz (3 cups) in the refrigerator to drink during the day. If you drink other beverages besides water (such as coffee, juice, or soft drinks), then you would need to pour out an equal amount of water from your container in the refrigerator.
