Heart Failure: Tracking Your Weight

You have a condition called heart failure. When you have heart failure, a sudden weight gain or a steady rise in weight is a warning sign. It means that your body is retaining too much water and salt. This could mean your heart failure is getting worse. If left untreated, it can cause problems for your lungs and result in shortness of breath. Weighing yourself each day is the best way to know if you’re retaining water. If your weight goes up quickly, call your healthcare provider. You'll be given instructions on how to get rid of the excess water. You'll likely need medicines and have to avoid salt. This will help your heart work better.

When to call your healthcare provider

Call your healthcare provider if you gain:

  • More than 2 pounds in 1 day

  • More than 5 pounds in 1 week

  • Or whatever weight gain you were told to report by your provider

This is often a sign of worsening heart failure and needs to be evaluated and treated. Your provider will tell you what to do next.

Tips for weighing yourself

Chart for recording weight every day.

  • Weigh yourself at the same time each morning, wearing the same clothes. Ideally, weigh yourself after urinating and before eating.

  • Use the same scale each day. Make sure the numbers are easy to read. Put the scale on a flat, hard surface. Don't put it on a rug or carpet.

  • Don't stop weighing yourself. If you forget 1 day, weigh yourself again the next morning.

How to use your weight chart

  • Keep your weight chart near the scale. Write your weight on the chart as soon as you get off the scale.

  • Fill in the month and the start date on the chart. Then write down your weight each day. Your chart will look like this:

  • Take your weight chart with you when you go to see your provider.
