This is a long-term observational study that follows patients with chronic airway diseases — including COPD, asthma, and conditions where both occur together. Researchers will collect your medical information and health history over time to learn more about how these diseases affect people and what factors influence their course. This is not a medication trial; instead, you'll be contributing to a research registry that helps doctors better understand and treat airway diseases.
Chronic airway diseases affect millions of people, but doctors still need more real-world information about how these conditions develop, progress, and respond to treatment in everyday patients. This registry will help researchers identify patterns and improve care for people living with these diseases.

You would visit Seoul National University Hospital (or one of their partner sites) for regular check-ups where doctors will ask about your symptoms, review your medical history, and perform breathing tests. They will also collect information about your current treatment and how you're doing. The study will follow you over time — possibly for several years — to track how your condition changes. There are no experimental medications; this is purely about gathering information to help science understand your disease better.
