Hypersensitivity Pneumonitis Overview

An immune response to inhaled organic substances like bird proteins, causing inflammation in the lungs.

The process of forming small, inflammatory clusters of cells called granulomas in the lungs.

When the body reacts to substances inhaled from bird droppings, causing a disease known as pigeon breeder's lung.

A period of fever, coughing, and difficulty breathing that starts within hours of exposure to an allergen.

The process of lung tissue becoming scarred and stiff due to long-term exposure to allergens.

A data structure that stores information in a key-value fashion, similar to a dictionary. Each key is unique and maps to a value.

A group of lung diseases where the lungs can't fill up properly. This means the total lung capacity (TLC) and forced expiratory volume (FEV) are reduced, but the forced vital capacity (FVC) is increased. The FEV/FVC ratio is also increased.

Fibrosis of the lung tissue, causing scarring and making it harder for the lungs to work. This can be caused by various reasons like exposure to dust, certain medications, or radiation.

A specific type of interstitial lung disease where the lung tissue becomes abnormally thick and scarred, leading to lung dysfunction. The cause is unknown, but it's thought to be related to various factors including genetics and environmental exposures.

A group of lung diseases caused by inhaling dust or particles in the workplace. These particles cause inflammation and scarring in the lungs, eventually leading to lung fibrosis.

A systemic disease that affects multiple organs, characterized by the formation of non-cancerous granulomas in tissues. It is often seen in people with African ancestry and is typically seen in young adults.
