A lung disease caused by an allergic reaction to inhaled organic substances (e.g., bird feathers, mold spores).

Lung disorders characterized by limited lung expansion, leading to reduced total lung capacity (TLC) and forced expiratory volume (FEV), while forced vital capacity (FVC) increases. The FEV/FVC ratio is elevated.

Interstitial lung diseases, like Idiopathic Pulmonary Fibrosis, and chest wall deformities such as severe obesity.

A type of immune response in Hypersensitivity Pneumonitis where immune cells form clusters (granulomas).

A progressive lung condition characterized by scarring of the lung tissue (fibrosis), leading to impaired breathing.

Fever, cough, and difficulty breathing that appear hours after exposure to the trigger.

Fibrosis of the lung tissue caused by prolonged exposure to specific particles in the workplace, such as asbestos or silica.

The symptoms of Hypersensitivity Pneumonitis usually go away if the exposure is removed.

Long-term exposure to the trigger can damage the lungs and lead to scarring (fibrosis).

A systemic disease characterized by the formation of granulomas (clusters of inflammatory cells) in various organs, primarily affecting African American women.
