Your body doesn’t get sick overnight. Before an emergency arises, it often sends subtle warning signs that most people mistake for tiredness, age, or stress.
Heart failure is a leading cause of hospitalization in adults, and what’s most dangerous is that its early symptoms often go unnoticed.
These are 13 early signs that may indicate your heart is starting to fail.
1. Shortness of breath when performing simple activities
If walking a few blocks, climbing stairs, or going to the mailbox leaves you breathless, it’s not just a lack of physical fitness.
It happens because your heart is no longer pumping enough oxygen to your muscles.
2. Needing more pillows to sleep
Sleeping almost sitting up to breathe is a sign called orthopnea .
When the heart isn’t pumping properly, fluid accumulates in the lungs when you lie down.
3. Waking up at night feeling like you’re choking
If you wake up suddenly feeling like you’re suffocating and have to sit up to breathe, it could be nocturnal dyspnea , a serious heart warning sign.
4. Extreme fatigue
It’s not normal tiredness.
It’s a deep fatigue that doesn’t improve with rest and makes simple tasks exhausting.
5. Swelling in ankles, feet or legs
When the heart fails, blood pools and fluid leaks into the tissues.
Shoes feel tighter at the end of the day, leaving marks on the skin.
6. Rapid weight gain
Gaining more than 2 kilos in just a few days is usually water retention , not fat.
It’s a clear sign that the body is accumulating water due to heart failure.
7. Urinating frequently at night
When you lie down, the fluid that accumulates during the day returns to your bloodstream and is eliminated by your kidneys.
If you wake up several times a night, it could be an early sign.
