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 to , or about to per day. Here are the amounts of fluid in some common equivalent household measures:

**Fluid equivalents**
Household measure	Equivalent fluid ounces	Equivalent milliliters
1 tablespoon of fluid	1/2 fluid ounce	15 milliliters
1/2 cup of fluid	4 fluid ounces	About 120 milliliters
1 cup of fluid	8 fluid ounces	About 250 milliliters
1 quart of fluid	32 fluid ounces	About 1,000 milliliters (1 liter)

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 () of fluid at each meal [3 x = , or ]. 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 () of fluid a day, you could have () divided into three meals and then another () 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.
