Are you wondering what causes fluid on the lungs and how it relates to heart disease?

Fluid on the lungs — known as pulmonary edema — happens when the heart isn't pumping blood efficiently. Blood backs up into the lungs, causing fluid to leak into the surrounding tissue. This makes it harder for oxygen to pass into the bloodstream, leading to breathing difficulties. This is most common with left-sided heart failure. Symptoms to watch for include:

- Shortness of breath, especially when lying down or being active
- A wet, persistent cough (sometimes with white or pinkish mucus)
- Needing extra pillows to sleep comfortably
- Feeling more breathless than usual during everyday tasks

These symptoms can worsen over time if left untreated, so it's important to flag any changes to your doctor promptly. If you experience chest swelling along with shortness of breath or chest pain or tightness, seek emergency care right away — pulmonary edema can become life-threatening quickly if not treated.

Your cardiologist is best placed to help manage this and tailor a plan to your specific situation.
