Popcorn lung is a nickname for a serious lung disease called bronchiolitis obliterans. It causes scarring of the small airways in the lungs, which makes it difficult to breathe.
Causes of Popcorn Lung
The most common cause of popcorn lung is exposure to diacetyl, a chemical used to give foods a buttery flavor. Diacetyl was once widely used in microwave popcorn, but many manufacturers have stopped using it because of the health risks.
Other causes of popcorn lung include:
- Inhaling other harmful chemicals, such as those found in some industrial settings
- Having a lung transplant
Symptoms of Popcorn Lung
The symptoms of popcorn lung can develop over months or even years. They include:
- A dry cough that won't go away
- Shortness of breath
- Wheezing
- Fatigue
Treatment of Popcorn Lung
There is no cure for popcorn lung, but there are treatments that can help manage the symptoms. These include:
- Medications to help open up the airways
- Oxygen therapy, if needed
- Lung transplantation, in severe cases
Prevention of Popcorn Lung
The best way to prevent popcorn lung is to avoid exposure to diacetyl and other harmful chemicals. If you work in a setting where you may be exposed to these chemicals, be sure to wear appropriate protective gear.
You can also help reduce your risk of popcorn lung by avoiding heavily processed foods, especially microwave popcorn. Look for popcorn that is flavored naturally, without artificial ingredients.
