Weigh yourself every day. A sudden weight gain can mean your heart failure is getting worse. Weigh yourself at the same time of day and in the same kind of clothes. Ideally, weigh yourself first thing in the morning after you empty your bladder, but before you eat breakfast. Your doctor will show you how to track your weight. Contact your doctor if you have a sudden, unexpected increase in your weight.
Your doctor may ask you to report if your weight goes up by more than 2 pounds in 1 day, 5 pounds in 1 week, on average. This is a sign that you are retaining more fluid than you should be. Clues to weight gain include checking your ankles for swelling, or noticing you are short of breath when you lie down.
