Hypersensitivity pneumonitis, or extrinsic allergic alveolitis, is a disease that causes inflammation in the lungs that can lead to permanent scarring. It can develop after repeated exposure to certain substances, such as bacteria, fungi, animal proteins, plants, and chemicals, which cause the lungs to develop an immune response.

There are specific types of hypersensitivity pneumonitis depending on what substance you have inhaled, including:

  • Farmer’s lung: Dust or spores rising from mouldy hay, grain and straw
  • Mushroom grower’s lung: Spores from mushrooms and their bedding
  • Bird fancier’s lung: In particles from feathers or bird droppings
  • Metal worker’s lung: Cutting fluid used in tool rooms or machine shops
  • Byssinosis: Cotton dust.
