What Is Popcorn Lung? Know Its Symptoms, Causes And Treatment
Popcorn lung is an alternative term for bronchiolitis obliterans (BO)
It was first identified among popcorn factory workers due to exposure to diacetyl, a food additive used in microwave popcorn for butter flavour.
BO is characterised by inflammation and scarring of the walls of the distal airways of the lungs.
The causes of this disease include childhood lower respiratory tract infections, transplantation, connective tissue disorders, and toxic fume inhalation.
The incidence has risen due to e-cigarette usage.
Symptoms include progressive breathlessness and a dry cough.
Pulmonary function tests show airflow obstruction, while diagnosis is done by chest X-ray and CT scan.
Early diagnosis and avoiding exposure to noxious stimuli can help reverse the condition.
Permanent lung damage can occur in severe cases, leading to a poor quality of life.
Treatment includes inhalers, nebulization, and oral corticosteroids for severe cases.
