Bronchial asthma is a chronic inflammatory disease of the airways, associated with recurrent, reversible airway obstruction with intermittent episodes of wheezing and dyspnea. Bronchial hypersensitivity is caused by various stimuli, which innervate the vagus nerve and beta adrenergic receptor cells of the airways, leading to bronchial smooth muscle constriction, hypersecretion of mucus, and mucosal edema.
The symptoms of bronchial asthma includes:
a feeling of tightness in the chest;
difficulty in breathing or shortness of breath;
wheezing; and
coughing (particularly at night).
Asthma triggers may include:
Tobacco smoke
Infections such as colds, flu, or pneumonia
Allergens such as food, pollen, mold, dust mites, and pet dander
Exercise
Air pollution and toxins
Weather, especially extreme changes in temperature
