how does diacetyl cause bronchiolitis obliterans
However, a recent study in animals suggests that combined exposure to another flavoring agent, butyric acid, might slightly increase the penetration of diacetyl into the lung. “When inhaled, diacetyl causes bronchiolitis obliterans – more commonly referred to as “popcorn lung” – a scarring of the tiny air sacs in the lungs resulting in the thickening and narrowing of the airways. Bronchiolitis obliterans can results from exposure to many different chemicals that cause inflammation and obstruction of the bronchioles, the smallest passages in the lungs.
