Pulmonary Edema Causes; What Causes Fluid In The Lungs?

Pulmonary edema, a condition of excess fluid accumulation in the lungs, is manifested by an unusual difficulty in breathing. It may occur suddenly or over a long time. Sudden breathing difficulty is a red flag that requires immediate medical attention.

What causes pulmonary edema?

1Heart failure

heart failure

The most common cause of pulmonary edema is congestive heart failure. Typically, the heart pumps blood from the lungs into the aorta, the biggest blood vessel in the body.

A diseased heart, however, may not pump the blood efficiently. Thus, with each heartbeat, more and more blood accumulates in the heart’s left ventricle. This excessive volume causes the pressure to increase in the pulmonary veins, the vessels that transport blood from the lungs to the heart. Eventually, the pressure becomes so excessive that a lot of blood stays in the lung vessels, and then moves into the air spaces.

The causes of congestive heart failure are many, from high blood pressure to heart attacks, and even coronary artery disease.
