Popcorn Lung - Causes, Treatment, Symptoms, and Diagnosis

When you breathe in, the air flows in your windpipe and further divides into two tubes that further divide into many more branches just like the trees, creating a very complex system. The smallest of these air tubes are called bronchioles and when they get irritated they narrow down, resulting in shortness of breath. Although the name popcorn lungs may sound strange, it is a well picked nick as bronchiolitis obliterans was found in the workers working in popcorn and dairy factories where the main harmful chemical causing this condition is found.
