Chronic Obstructive Pulmonary Disease
• “Preventable and treatable disease characterized by airflow limitation, resulting from an abnormal inflammatory reaction to inhaled particles (smoking) and associated with associated with co-morbidities”co-morbidities”

Co-morbidity in COPD
• In patients with COPD, not all Co-Morbidites are created equal
• From the Solar System to the Milky Way (Multi-morbidity)
• We need to re-think how we link diseases….perhaps by pathobiology?

A Road to the Future
• Some co-morbidities of COPD share pathobiological responses to injurious agents and occur more frequently than chance would have it.
• We may have to shift from organ oriented pathophysiology to mechanistic pathobiology
• Comprehensive evaluation of patients for commonly occurring diseases
• Merging of specialties? Back to Holistic Medicine
