What Is Popcorn Lung
Popcorn lung is the common name for bronchiolitis obliterans, a condition that scars and narrows the smallest airways in the lungs. The name comes from cases linked to inhaling diacetyl, a butter-flavoring chemical used in some microwave popcorn factories.
Can Popcorn Lung Kill You
Severe popcorn lung can be life threatening. The scarring makes it hard to breathe, and in rare cases respiratory failure or related complications can lead to death. Most people with mild exposure do not develop serious disease, but early diagnosis matters.
Common Causes and Risk Factors
Risk comes mainly from breathing in certain chemicals, especially diacetyl, in workplaces like flavoring plants. E-cigarette vapor, industrial cleaning fumes, and some food flavorings may also increase risk. Smoking and existing lung disease can worsen outcomes.
There is no single test that can definitively diagnose popcorn lung, and treatment focuses on slowing damage and managing symptoms. If you have persistent cough or shortness of breath after chemical exposure, consult a healthcare professional.
