Lung congestion; Lung water; Pulmonary congestion; Heart failure - pulmonary edema DefinitionPulmonary edema is an abnormal buildup of fluid in the lungs. This buildup of fluid leads to shortness of breath. CausesPulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the blood vessels that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs. This fluid reduces normal oxygen movement through the lungs. These two factors combine to cause shortness of breath. Congestive heart failure that leads to pulmonary edema may be caused by:

Following a healthy diet that is low in salt and fat, and controlling your other risk factors can reduce the risk of developing this condition. ReferencesMann DL.
