Asthma Severity

Asthma severity is a key concept in asthma control. Previously, severity was defined before treatment began. More recently, severity has been measured based on the intensity of treatment required to achieve good asthma control.[6] Asthma severity is influenced by the underlying disease activity as well as by the patient's phenotype and responsiveness to treatment. Patients' pathological and physiological markers may help characterize asthma severity and act as surrogate measures of future risk.
