Asthma is a clinical syndrome characterized by episodic reversible airway obstruction, increased bronchial reactivity, and airway inflammation. Asthma is now recognized to result from complex interactions among inflammatory cells, their mediators, airway epithelium and smooth muscle, and the nervous system. |

Asthma is a chronic inflammatory disorder of the airways characterized by an obstruction of airflow, which may be completely or partially reversed with or without specific therapy. Airway inflammation is the result of interactions between various cells, cellular elements, and cytokines. |

Asthma or hyperreactive airway disease is a very common clinical syndrome and is the most common cause of hospitalization for children in the United States. Despite recent advances in understanding the pathophysiology and treatment of asthma, it continues to have significant medical and economic impacts worldwide. |

Exercise-induced asthma (EIA) is a condition of respiratory difficulty that is triggered by aerobic exercise lasting several minutes. Symptoms may resemble those of allergic asthma, or they may be much more vague and go unrecognized, resulting in probable underreporting of the disease. |

Asthma is a heterogeneous lung disease with airway obstruction that is partially or completely reversible, spontaneously or with treatment. Changes in pulmonary function that are peculiar to pregnancy include a 20% increase in oxygen demand and maternal metabolism, a 40% increase in minute ventilation, and increased tidal volume. |
