asthma Scientific  
/ ăzmə /
  1. A common inflammatory disease of the lungs characterized by episodic airway obstruction caused by extensive narrowing of the bronchi and bronchioles. The narrowing is caused by spasm of smooth muscle, edema of the mucosa, and the presence of mucus in the airway resulting from an immunologic reaction that can be induced by allergies, irritants, infection, stress, and other factors in a genetically predisposed individual. Common symptoms of asthma include wheezing, coughing, and shortness of breath.


asthma Cultural  
  1. A chronic disease of the respiratory system, characterized by sudden, recurring attacks of difficult breathing, wheezing, and coughing. During an attack, the bronchial tubes go into spasms, becoming narrower and less able to move air into the lungs. Various substances to which the sufferer has an allergy, such as animal hair, dust, pollen, or certain foods, can trigger an attack.

Etymology

Origin of asthma

First recorded in 1350–1400; Middle English, from Greek: “a panting,” akin to aázein “to breathe hard”; replacing Middle English asma, from Medieval Latin, from Greek ásthma

Explanation

Asthma is a respiratory condition that involves allergies and your lungs: people with asthma have trouble breathing at times. Asthma is a very common disorder that makes breathing difficult. An allergic reaction, too much exercise, or just being stressed out can bring on an asthma attack. When someone has an asthma attack, it's very hard for them to get a good breath of air. Fortunately, asthma is not usually a life-threatening disease, and people who are asthmatic are fine most of the time.
