By Dr. Pavan Agrawal, Interventional Cardiologist, Amravati · October 2026 · 2 min read

Feeling breathless is common and has many causes, including lung disease, anaemia, weight gain and anxiety. But it can also signal a heart problem.

Heart-related clues

• Breathlessness on walking that was easy before
• Needing extra pillows or waking at night gasping
• Swollen feet or ankles, or sudden weight gain
• Chest discomfort or palpitations along with it

When it is urgent

• Sudden severe breathlessness
• Breathlessness with chest pain, fainting or a bluish tinge

What to expect

• The doctor may advise ECG, echo and blood tests
• Treatment depends on the cause, so avoid self-medicating
