My mother has asthma and has been diagnosed with hypersensitivity pneumonia. Can you explain what hypersensitivity pneumonia is and its treatment?
Hypersensitivity pneumonia is a condition in which the lungs become inflamed due to an allergic reaction to inhaled substances such as dust, mould, chemicals, or animal proteins. It can cause flu-like symptoms, such as cough, breathlessness, fever, chills, and tiredness. Treatment primarily involves avoiding the triggers and taking prescribed corticosteroids (such as prednisone) to reduce inflammation. In severe cases, doctors may consider using immunosuppressants (such as azathioprine) or antifibrotics (such as pirfenidone) to control the immune response or protect the lungs.
