哮喘是一种常见的慢性呼吸道疾病，主要表现为气道反复发作的喘息、胸闷、气短和咳嗽。它的本质是气道炎症和气道对多种刺激物过度反应，导致气道收缩和气流受限，这种阻塞通常可以被药物或自然过程部分或完全缓解。哮喘发作时，患者会感觉呼吸困难，尤其是在夜间或清晨更容易加重，严重时可能危及生命。常见的诱因包括过敏原、运动、冷空气、呼吸道感染、空气污染和情绪压力等。哮喘在儿童和成人中都很常见，对生活质量有明显影响，未控制好的哮喘会限制日常活动、影响睡眠并增加医疗开支。诊断通常依靠详细病史、体检以及肺功能检查，如用药前后可逆性检测或峰流速监测。治疗以长期控制炎症为主，常用吸入性糖皮质激素和支气管扩张剂，急性发作时需要快速缓解药物并可能需要急诊处理。管理还包括识别并避免触发因素、制定个人化的应对计划、按医嘱使用药物以及定期随访。通过规范治疗和自我管理，大多数患者可以将症状控制在很低水平，保持正常生活和工作学习能力。理解哮喘的特点并积极配合治疗，对预防严重发作和改善长期预后非常重要。
