Popcorn lung, or bronchiolitis obliterans, is, at present, an irreversible lung disease. While plain bronchiolitis is a viral disease common in children, bronchiolitis obliterans is a new condition that's appearing in a few select populations. Here is a look at the causes of popcorn lung.
What is Popcorn Lung?
Popcorn lung causes coughing and difficulty breathing when the bronchioles of the lungs become overgrown with scarring. In more extreme cases, it may lead to night sweats or fevers. The effects are remarkably similar to chronic obstructive pulmonary disease (COPD).
Where Popcorn Lung Got It’s Name
The initial cases of this condition occurred in a popcorn plant. Diacetyl, an agent used for flavoring the popcorn, was deemed the culprit. In fact, not only were several workers affected by inhaling the diacetyl, but also one man who consumed two bags a day. However, the workers were exposed to so much more that their symptoms were considerably worse, as higher concentrations can be more damaging.
The Danger of Electronic Cigarettes
Despite smokers hopes to the contrary, not all electronic cigarettes and vaporizers are as safe an alternative to tobacco products as they were led to believe. Several new studies have come out flouting diacetyl’s danger and presence in several of the liquids used for “vaping.” Not every flavor contains the dreaded diacetyl, but those that do can be a serious problem—especially considering it can take years for symptoms to really show up.
Beyond Popcorn and Cigarettes
The CDC also reported on employees in coffee flavoring plants that developed bronchiolitis obliterans, suggesting exposure to several flavorings could be a danger. The National Institute for Occupational Safety and Health is currently looking into the dangers of working in close quarters with flavorings.
Furthermore, some studies suggest more serious chemicals like bleach, ammonia, and other strongly scented compounds may be a risk factor for developing popcorn lung. Respiratory infections may also play a part, as can a bad reaction to some medications.
