Fluid restriction means that you need to limit the amount of liquid you have each day. Fluid restriction is needed if your body is holding water. This is called fluid retention. Fluid retention can cause health problems, such as tissue and blood vessel damage, long-term swelling, and stress on the heart. Ask your healthcare provider how much liquid you can have each day.
Call your local emergency number (911 in the US) if:
- You have shortness of breath.
- You have chest pain.
Call your doctor if:
- You have a severe headache that does not get better with medicine.
- You gain 2 pounds in 1 day.
- Your skin is tight and shiny.
- You are urinating very little, even though you are regularly drinking liquids.
- You have signs of dehydration, such as a headache, dark yellow urine, dry eyes or mouth, or a fast heartbeat.
- You have questions or concerns about your condition or care.
How to track your liquid intake:
Keep a record of the amount of every liquid you have each day.
- Liquids can be measured in milliliters (mL), liters (L), ounces (oz), or cups (c). Choose a measurement that is familiar to you. Your healthcare provider or dietitian can show you how to change units of measurement if needed. For example, you may be tracking liquids in mL, but the container lists the amount in ounces. Your provider or dietitian can show you how to find how many mL are in the container. You may be able to use a chart or computer program to make this easier.
- Remember to record the amount of liquid you use to swallow your medicines.
- Soup needs to be separated into liquids and solids before you eat it. Write down the amount of liquid before you eat.
Amount of liquid in common foods and drinks:
Liquid from both foods and drinks should be counted toward your daily liquid limit:
- 12 ounces (1 can) of soda (332 mL)
- 1 cup of juice (215 mL) or 2% milk (217 mL)
- 6 ounces of coffee (175 mL) or 6 ounces of tea (168 mL)
- 1 cup of gelatin (200 mL)
- 1 single popsicle (45 mL)
- 1 cup of ice cream (100 mL) or sherbet (127 mL)
- 1 cup of yogurt (182 mL) or cottage cheese (185 mL)
- 1 cup of raw peaches, canned in juice (218 mL)
- 1 cup of grapes (120 mL) or berries (130 mL)
- 1 cup of watermelon (140 mL)
- 1 cup of cooked broccoli (170 mL) or creamed corn (200 mL)
Track your liquid intake:
Keep a record of the amount of liquid you get each day. Record the exact amount of liquid in mL. To do this, measure the amount of ounces that your glass holds. Multiply the amount in ounces by 30 to get the amount in mL. For example, a glass may hold 16 ounces of liquid. To get the amount in mL, multiply 16 by 30. The total amount of liquid in this glass is 480 mL.
The following list of medications are in some way related to or used in the treatment of this condition.
Monitor your weight:
Weigh yourself at the same time every day, with the same scale. Record your weight so you can compare it to your other daily weights. You may be retaining fluid if your weight goes up by more than 2 pounds in 24 hours. If you have a sudden weight loss, you may be dehydrated.
Other things to remember about fluid balance:
- Large amounts of sodium from foods can cause fluid retention. Sodium is found in table salt, salted snacks, bacon, cheddar cheese, soy sauce, lunch meat, and canned vegetables. Ask your healthcare provider how much sodium you can have each day.
- Diuretics are medicines that can help your body get rid of extra fluid. If you take diuretics, follow your healthcare provider's directions. You may become dehydrated if you take too much of this medicine.
Help relieve thirst:
- Sip your liquid. Small sips throughout the day may help relieve or prevent thirst.
- Gum or hard candy can help your mouth feel less dry.
- Rinse your mouth. You can use mouthwash or water. Do not swallow after you rinse.
- Limit salt. Salt may make your thirst worse. Do not eat foods that are high in salt, such as crackers. Do not add salt to your food.
- Frozen liquids may help with thirst, and can help you get liquids more slowly. You will still need to count the liquid in your daily amount. Before you have these for the first time, figure out the amount of liquid they contain. For example, you can let a few ice chips or a popsicle melt and measure the amount of liquid. Record the amount so you will know it the next time you have the ice chips or popsicle.
Follow up with your healthcare provider as directed:
Your healthcare provider may recommend that you see a dietitian on a regular basis. A dietitian can help you create a plan to get the right amount of liquid each day. The dietitian can also help you calculate the amount of liquid in the foods you eat. Write down your questions so you remember to ask them during your visits.
