Not usually: Not usually, however very heavy exposure to the inciting agent or very severe responses can cause severe lung injury and result even in respiratory failure. Even in these situations if medical care is sought out the response to steroid medicine is usually very good. Repeat exposures that are untreated can cause a more chronic scarring of the lung or pulmonary fibrosis that can shorten ones life.

Inflammation in lung: Hypersensitivity pneumonitis is a lung disease in which an inhaled substance capable of triggering an immune response called and "antigen" is inhaled and causes an illness that is like pneumonia, with fever , shortness of breath etc.. Symptoms resolve when exposure to the antigen is stopped, but repetitive exposure can result in chronic scar formation in the lung. Steroid medicine can also help.
