Hypersensitivity Pneumonitis, also known as extrinsic allergic alveolitis, is a respiratory condition characterized by inflammation of the lung tissue. It is caused by an immune response to inhaled allergens such as dust, mold, or chemicals. The condition primarily affects the small air sacs in the lungs, known as alveoli, leading to symptoms such as coughing, shortness of breath, and chest tightness.

These terms are used interchangeably to describe the same condition, highlighting the various occupational or environmental triggers that can lead to the development of Hypersensitivity Pneumonitis. It is important to note that the symptoms and severity of the condition can vary depending on the individual and the specific allergen involved.
Diagnosis of Hypersensitivity Pneumonitis involves a thorough evaluation of the patient's medical history, physical examination, and specialized tests such as pulmonary function tests, chest X-rays, and high-resolution computed tomography (HRCT) scans. Treatment typically involves identifying and avoiding the triggering allergen, along with the use of corticosteroids to reduce inflammation and manage symptoms.
If left untreated, Hypersensitivity Pneumonitis can progress to irreversible lung damage and respiratory failure. Therefore, early recognition and appropriate management are crucial in improving outcomes for individuals affected by this condition.
