A review of the burden and management of mild asthma in adults — Implications for clinical practice

Mild asthma is present in 50–75% of patients with asthma and is defined by the Global Initiative for Asthma as asthma that can be well controlled with low-intensity treatments (Steps 1 and 2). Despite this definition, ‘mild’ asthma is often not well controlled in reality, and can have a significant impact on an individual's symptom burden and quality of life.
