Allergies can contribute to the development and symptoms of COPD, but are typically not the only causative factor. Patients with allergic asthma have a 14x greater probability of developing COPD later in life and COPD and Asthma can coexist. COPD is diagnosed due to irreversibility and the type of inflammation (neutrophilic-smoking/corticosteroids) vs allergic Asthma, which is usually reversible and is a different type of inflammation (eosinophilic-allergic). A theory that is gaining some traction based on the fact that corticosteroids reduce eosinophilic/allergic inflammation but increase neutrophilic/irreversible inflammation. Is it the allergies, asthma or the meds?
