be checked.
2. Shortness of Breath
Breathlessness during mild activity—or even at rest—may suggest the heart is not delivering enough oxygen or that fluid is accumulating in the lungs.
Watch for:
Waking up at night feeling short of breath
Needing extra pillows to sleep comfortably
Symptoms worsening when lying flat
3. Unusual or Persistent Fatigue
Extreme tiredness that does not improve with rest may be a sign that the heart is struggling to circulate oxygen-rich blood efficiently.
Unlike normal fatigue:
It persists despite adequate sleep
Everyday tasks feel unusually exhausting
There is no clear explanation such as stress or illness
4. Dizziness or Lightheadedness
Reduced blood flow can cause dizziness, unsteadiness, or near-fainting episodes, especially during physical activity or when standing quickly.
Seek medical attention if:
Episodes occur repeatedly
Dizziness comes with chest discomfort or palpitations
You actually faint
5. Sleep Disturbances
Heart-related issues may cause breathing difficulties when lying
