Heart Failure Symptoms
Symptoms of heart failure start to happen when your heart cannot pump enough blood to the rest of your body. In the early stages, you may:
- Feel tired easily.
- Be short of breath when you exert yourself.
- Feel like your heart is pounding or racing (palpitations).
- Feel weak or dizzy.
As heart failure gets worse, fluid starts to build up in your lungs and other parts of your body. This may cause you to:
- Feel short of breath even at rest.
- Have swelling (edema), especially in your legs, ankles, and feet.
- Gain weight. This may happen over just a day or two, or more slowly.
- Cough or wheeze, especially when you lie down.
- Need to urinate more at night.
- Feel bloated or sick to your stomach.
If your symptoms suddenly get worse, you will need emergency care.
