Pulmonary edema is a condition in which the lungs fill with fluid. It’s also known as lung congestion, lung water, and pulmonary congestion. When pulmonary edema occurs, the body struggles to get enough oxygen and you start to have shortness of breath.

Symptoms of pulmonary edema
In cases of pulmonary edema, your body will struggle to gain oxygen. This is due to the amount of increasing fluid in the lungs preventing oxygen moving into the bloodstream. Symptoms may continue to worsen until you get treatment.

Symptoms depend on the type of pulmonary edema.

Long-term pulmonary edema
The symptoms for long-term pulmonary edema include:

shortness of breath when being physically active
difficulty breathing when lying down
wheezing
waking up at night with a breathless feeling that goes away when you sit up
rapid weight gain, especially in the legs
swelling in the lower part of the body
fatigue
High-altitude pulmonary edema
Pulmonary edema due to altitude sickness, or not getting enough oxygen in the air, will have symptoms that include:

headaches
irregular, rapid heartbeat
shortness of breath after exertion and during rest
coughing
fever
difficulty walking uphill and on flat surfaces
