哮喘全球倡议（吉娜2004）将哮喘定义为气道慢性炎症性疾病，其中许多细胞和细胞成分发挥作用。慢性炎症导致气道高反应性的增加，导致反复发作的喘息、气促、胸闷、咳嗽，尤其是在夜间或清晨。这些情节通常与广泛但可变气流阻塞，往往是可逆的，无论是自发或治疗。这是一个操作性描述哮喘的气道炎症的功能性后果的基础上。哮喘没有统一的分类，也许是因为这种疾病有广泛的诱发因素和临床表现，在过去的三年里，西方世界哮喘的发病率显著增加。哮喘患者禁用攻击经验严重呼吸困难、咳嗽、喘息、支气管痉挛引发的突然发作。发作之间，患者可能几乎无症状。在某些情况下，这些攻击是由运动和寒冷引起的，或者通过暴露于患者先前被致敏的过敏原，但往往没有触发 .

The Global Initiative for Asthma (GINA 2004) defines Asthma as a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. The chronic inflammation causes an associated increase in airway hyper-responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or in the early morning. These episodes are usually associated with widespread but variable airflow obstruction that is often reversible either spontaneously or with treatment. This is an operational description of asthma based on the functional consequences of airway inflammation. There is no uniform classification for Asthma, perhaps because the condition has such a wide spectrum of predisposing factors and clinical presentations.There has been a significant increase in the incidence of asthma in the Western world in the past three decades. Patients with asthma experience disabling attacks of severe dyspnea, coughing, and wheezing triggered by sudden episodes of bronchospasm. Between attacks, patients may be virtually asymptomatic. In some cases, the attacks are triggered by exercise and cold or by exposure to an allergen to which the patient has previously been sensitized, but often no trigger can be identified
