Asthma is clinically defined as a chronic inflammatory disorder of the airways, though it is historically and colloquially referred to by several alternative terms including bronchial asthma, reactive airway disease, and asthmatic bronchitis. Common Synonyms and Historical Terms While Asthma is the universally accepted medical term, you may encounter older or descriptive labels in medical records or literature. Historically, the term "bronchial asthma" was used to distinguish the condition from "cardiac asthma," which refers to wheezing caused by heart failure.

While Asthma is the universally accepted medical term, you may encounter older or descriptive labels in medical records or literature. Historically, the term "bronchial asthma" was used to distinguish the condition from "cardiac asthma," which refers to wheezing caused by heart failure. In pediatric settings, clinicians sometimes use the term "reactive airway disease" (RAD) as a placeholder diagnosis before a definitive Asthma diagnosis is confirmed. You might also see it referred to as "asthmatic bronchitis," though this term is now largely discouraged as it lacks clinical precision.
In international medical systems, the condition is standardized to ensure consistent care. According to the ICD-11 (International Classification of Diseases), it is classified under "Chronic lower respiratory diseases" as Asthma. In the OMIM (Online Mendelian Inheritance in Man) database, which tracks the genetic components of the disease, it is often referenced under the entry "Asthma, susceptibility to." Because Asthma is a heterogeneous condition with various triggers—such as allergic or non-allergic factors—some medical records may specify subtypes like "atopic asthma" or "occupational asthma."
The existence of various synonyms for Asthma stems from centuries of medical observation. Before the underlying pathophysiology of airway inflammation and bronchial hyper-responsiveness was fully understood, doctors named the condition based on its primary symptom: the Greek word asthma literally means "panting" or "labored breathing." As our understanding of the immune system and lung physiology has evolved, medical professionals have moved toward using the singular, standardized name to avoid confusion with other conditions that cause wheezing, such as COPD or viral bronchiolitis.
