Allergic Lung Diseases refer to a group of conditions in which the lungs become inflamed due to exposure to airborne allergens such as dust mites, pollen, molds, animal dander, fungal spores, or certain workplace irritants. These allergies trigger an exaggerated immune response, leading to symptoms like coughing, wheezing, chest tightness, breathlessness, and recurring respiratory infections. Common allergic lung conditions include allergic asthma, hypersensitivity pneumonitis, and allergic bronchopulmonary aspergillosis (ABPA). Early diagnosis with allergy testing, imaging, and pulmonary function tests helps identify the specific trigger and guide treatment. Proper management—including avoidance of allergens, medications, inhalers, and sometimes immunotherapy—helps control symptoms and prevent long-term lung damage.
