Alveolar Proteinosis

Alveolar proteinosis is a lung condition characterized by the buildup of a thick substance called surfactant in the air sacs of the lungs. This surfactant is normally important for keeping the lungs working properly, but when it accumulates excessively, it can lead to breathing difficulties. Symptoms may include shortness of breath and a persistent cough. The exact cause is often unknown, but it can sometimes be related to immune system issues or exposure to certain environmental factors. Treatment may involve procedures to remove the excess substance and improve lung function.
