What is it called if there water in your lungs?

The medical term for the condition where there is water in the lungs is pulmonary edema. It occurs when fluid accumulates in the tiny air sacs (alveoli) in the lungs, making it difficult to breathe. Pulmonary edema can be caused by a variety of factors, including heart failure, kidney failure, pneumonia, and certain medications. Symptoms of pulmonary edema may include shortness of breath, wheezing, coughing, fatigue, and swelling in the feet, ankles, and abdomen. Treatment typically involves medications to improve heart and kidney function, as well as oxygen therapy and fluid restriction.
