Popcorn Lung (Bronchiolitis Obliterans Symptoms, Causes, Life Expectancy Center

Popcorn lung is a term for the lung disease bronchiolitis obliterans. Popcorn lung is caused by diacetyl and 2,3-pentanedione, chemicals used when manufacturing flavorings for food certain products like popcorn, coffee. E-cigarettes also may cause popcorn lung. Diacetyl and 2,3-pentanedione damage lung tissue that is irreversible.

Symptoms of popcorn lung develop gradually over time. The main symptoms are chronic cough and shortness of breath. Other symptoms may include night sweats, weight loss, and fever. Symptoms of severe exposure to diacetyl and 2,3-pentanedione include inflammation of the skin, eyes, nose, and/or throat.

Popcorn lung often resembles tobacco-related COPD (chronic obstructive pulmonary disease) so it often is difficult to diagnose. Lung biopsy and surgery may be necessary.

There is no cure for popcorn lung. Life expectancy for a person with (bronchiolitis obliterans) depends upon how early the disease was diagnosed and level of exposure to diacetyl and 2,3-pentanedione. Read more: Popcorn Lung (Bronchiolitis Obliterans Symptoms, Causes, Life Expectancy Article
