Asthma 493- >
  • A chronic disease in which the bronchial airways in the lungs become narrowed and swollen, making it difficult to breathe. Symptoms include wheezing, coughing, tightness in the chest, shortness of breath, and rapid breathing. An attack may be brought on by pet hair, dust, smoke, pollen, mold, exercise, cold air, or stress.
  • A chronic respiratory disease manifested as difficulty breathing due to the narrowing of bronchial passageways.
  • A form of bronchial disorder with three distinct components: airway hyper-responsiveness (respiratory hypersensitivity), airway inflammation, and intermittent airway obstruction. It is characterized by spasmodic contraction of airway smooth muscle, wheezing, and dyspnea (dyspnea, paroxysmal).
  • Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen. That makes them very sensitive, and they may react strongly to things that you are allergic to or find irritating. When your airways react, they get narrower and your lungs get less air.symptoms of asthma include
    • wheezing
    • coughing, especially early in the morning or at night
    • chest tightness
    • shortness of breath
    not all people who have asthma have these symptoms. Having these symptoms doesn't always mean that you have asthma. Your doctor will diagnose asthma based on lung function tests, your medical history, and a physical exam. You may also have allergy tests.when your asthma symptoms become worse than usual, it's called an asthma attack. Severe asthma attacks may require emergency care, and they can be fatal.asthma is treated with two kinds of medicines: quick-relief medicines to stop asthma symptoms and long-term control medicines to prevent symptoms.
  • Form of bronchial disorder associated with airway obstruction, marked by recurrent attacks of paroxysmal dyspnea, with wheezing due to spasmodic contraction of the bronchi.
