How can hypersensitivity pneumonitis be triggered?

By high doses of radiation exposure
From chronic stress and anxiety
Through exposure to microbial growth due to water damage
By consuming contaminated food

The correct answer is: Through exposure to microbial growth due to water damage

Exposure to high doses of radiation is associated with another lung disease, irradiation pneumonitis, rather than hypersensitivity pneumonitis. Chronic stress and anxiety can aggravate already existing hypersensitivity pneumonitis, but it is not the direct cause of the condition. Although contaminated food can cause food poisoning and result in respiratory symptoms, it is not a known trigger of hypersensitivity pneumonitis. Exposure to microbial growth due to water damage, specifically mold or bacteria, is a known trigger for hypersensitivity pneumonitis. The immune system reacts to these microbes, causing inflammation in the lungs. This is why it is important to address any water damage in buildings and homes to prevent the growth of these triggers.
