hypersensitivity pneumonitis is an allergic reaction that causes inflammation (swelling and tenderness) in and around the air sacs (alveoli) of the lungs and the smallest airways (bronchioles). it usually takes exposure to large amounts of these materials (allergens) frequently over a period of time before a sensitivity and reaction develop. in the most serious cases the combination of the allergic reaction and the immune system’s reactions can cause lung damage. the inflammation is a result of white blood cells building up in the walls of the alveoli and bronchioles. once a person has developed hypersensitivity to a material or organism, he or she may experience symptoms the next time exposure occurs. the symptoms usually clear up in a day or two if there is no more exposure to the reaction-causing material.
in one form of hypersensitivity pneumonitis, a cough and shortness of breath may take days or weeks to develop and be so severe that the person needs to be hospitalized. symptoms in this case may include shortness of breath during exercise, coughing up of sputum, tiredness and a gradual weight loss. if the diagnosis is unclear or an infection is suspected, doctors may do a biopsy. the tissue can be removed during a bronchoscopy, when the lungs are being checked through a scope in the lungs. sometimes during a bronchoscopy, the lung may be washed out with fluid that carries away cells. after an acute episode of hypersensitivity pneumonitis, a person can usually recover without treatment if he or she has no more contact with the allergen. if episodes go on for a long period of time or come back often, a person may suffer permanent lung damage and growing difficulty with breathing (dyspnea).
these allergens may be present at home, at work, or in the air. you don’t always have the allergy right away: it may take a couple of months or a couple of years to start. some people develop symptoms after inhaling a lot the dust all at once or after inhaling small amounts over and over again. if you stop inhaling the allergen, the irritation can get better in a few days. your first symptoms may feel like the flu. if you inhale the allergens over and over, you may have these symptoms: there are more than 300 known allergens that, when inhaled as a fine dust, can cause hypersensitivity pneumonitis. if you work in one of these jobs and have a family history, however, you may get the disease.
