Bronchiolitis obliterans (BO), also known as obliterative bronchiolitis, constrictive bronchiolitis and popcorn lung, is a disease that results in obstruction of the smallest airways of the lungs (bronchioles) due to inflammation. [1] [6] Symptoms include a dry cough, shortness of breath, wheezing and feeling tired. [1]
Chronic industrial exposure to diacetyl fumes, such as in the microwave popcorn production industry, has been associated with bronchiolitis obliterans, a rare and life-threatening form of non-reversible obstructive lung disease in which the bronchioles (small airway branches) are compressed and narrowed by fibrosis (scar tissue) and/or ...
In 2012, Wayne Watson, a regular microwavable popcorn consumer for years, was awarded US$7.27 million in damages from a federal jury in Denver, which decided his lung disease was caused by the chemicals in microwave popcorn and that the popcorn's manufacturer, Gilster-Mary Lee Corporation, and the grocery store that sold it should have warned ...
As of 5 September 2019, the Illinois Department of Public Health reported 42 cases of lung illness, seven that were still being investigated, and one death. [26] Severe lung illness among young adults and youth who used vaping products required hospitalization in 11 cases in Wisconsin, and others were being investigated in August 2019. [27]
While patchy bilateral disease is typical, there are unusual variants of organizing pneumonia where it may appear as multiple nodules or masses. One rare presentation, focal organizing pneumonia, may be indistinguishable from lung cancer based on imaging alone, requiring biopsy or surgical resection to make the diagnosis. [20]
Respiratory diseases, or lung diseases, [1] are pathological conditions affecting the organs and tissues that make gas exchange difficult in air-breathing animals. They include conditions of the respiratory tract including the trachea , bronchi , bronchioles , alveoli , pleurae , pleural cavity , the nerves and muscles of respiration .

Microwaveable popcorn represents a special case, since it is designed to be cooked along with its various flavoring agents. One of these formerly common artificial-butter flavorants, diacetyl, has been implicated in causing respiratory illnesses in microwave popcorn factory workers, also known as "popcorn lung".
