Abstract
Work-related asthma is common yet underdiagnosed. It is a significant cause of morbidity and socioeconomic loss. Diagnosis is often difficult, and requires a strong index of suspicion and careful investigation. The Canadian Thoracic Society has endorsed the recent American College of Chest Physicians consensus statement on work-related asthma. The present document illustrates the advised approach to diagnosis and management of work-related asthma using case-based examples of occupational asthma and work-exacerbated asthma. The main statements of advice from the American College of Chest Physicians consensus statement are reproduced with permission.
