What Is Popcorn Lung?

     Popcorn Lung, or Bronchiolitis Obliterans, is quaint  but severe lung disease that damages the smallest airways in the lungs, leading to progressive breathing difficulties.

      The condition gained public attention when it was linked to diacetyl, a chemical used in butter-flavoured popcorn.  

       However, this disease is now recognized in many environments, including industrial exposure and e-cigarette use.

       Bronchiolitis Obliterans is not cancer, but its effects can be just as serious.

       It causes inflammation and scarring that blocks airflow and permanently damages the lungs.

1. Popcorn Lung Is Caused by More Than Just Popcorn

       Although named after its link to workers in popcorn factories, diacetyl is not the only culprit.

       The disease can result from exposure to:

• Fumes from industrial chemicals
• E-cigarette and vaping aerosols
• Respiratory infections
• Autoimmune disorders
• Chemical warfare agents (in rare cases)

2. Symptoms of Popcorn Lung Mimic Other Common Lung Disorders

       The early symptoms of Popcorn Lung (Bronchiolitis Obliterans) often resemble chronic bronchitis or asthma, making it easy to miss. These include:

• Dry, persistent cough
• Shortness of breath (especially after exertion)
• Wheezing
• Fatigue
• Fever and night sweats (in some cases)

       Early diagnosis is critical to managing the disease and avoiding permanent damage.

3. Diagnosis of Popcorn Lung, Involves High-Resolution Imaging & Lung Function Tests

      Doctors typically rely on HRCT scans, spirometry, and sometimes lung biopsy to confirm Popcorn Lung (Bronchiolitis Obliterans).  

      There is no single definitive test, which makes expert evaluation essential.

4. There Is No Cure for Popcorn Lung, but Treatment Can Slow Progression

      There is no known cure for popcorn lung. However, the following options may slow the disease:

• Corticosteroids to reduce inflammation
• Immunosuppressive therapy
• Oxygen therapy
• Pulmonary rehabilitation
• Avoidance of further chemical exposure

In severe cases, lung transplantation may be required.

5. Prevention of Popcorn Lung Is Key.

       The best approach is prevention, especially in high-risk industries or for frequent vape users. Regulatory agencies are increasingly monitoring chemical use in flavourings and electronic inhalants.
