Hypersensitivity Pneumonitis

Hypersensitivity pneumonitis is a rare inflammatory lung disease caused by repeatedly breathing in dusts, moulds or other particles, such as those from birds, hay or contaminated water. It can cause cough, breathbreathlessness and tiredness, and in some people leads to scarring of the lungs. Treatment centres on avoiding the trigger and, when needed, medicines that calm inflammation.
