Heart failure is more common than you think, but its early signs are often subtle and easily mistaken for everyday fatigue or stress. According to cardiac surgeons, catching these warning signals early can make a huge difference.

1. Persistent Fatigue

Feeling unusually tired even after adequate rest can be an early warning. This happens because the heart struggles to pump blood efficiently, leaving your muscles and organs starved of oxygen.

2. Unexplained Bloating or Weight Gain

Fluid retention in the body can lead to abdominal bloating or sudden weight gain. Pay attention if your clothes or rings feel tighter than usual.

3. Shortness of Breath

Difficulty breathing, especially during light activities or while lying down, may indicate your heart isn’t circulating blood effectively.

4. Swollen Ankles, Feet, or Legs

Swelling in the lower extremities is a classic symptom of fluid buildup, signaling that the heart is struggling to return blood from the extremities.

5. Irregular or Rapid Heartbeat

Palpitations or a racing heart can occur as the heart compensates for reduced pumping efficiency.

6. Persistent Cough or Wheezing

Fluid accumulation in the lungs can trigger a cough, sometimes producing white or pink-tinged mucus.

7. Reduced Ability to Exercise

Activities that were once easy may feel exhausting or leave you winded due to insufficient blood and oxygen delivery to your muscles.

Bottom line: heart failure often creeps in quietly. Early recognition of these subtle signs and timely medical attention can prevent serious complications and improve quality of life.
