COPD affects everyone differently. Doctors use Groups A, B and E to classify patients based on symptom severity and flare-up risk. Knowing your group helps you recognize changes early and manage your condition more effectively.
  • Group A: Mild Symptoms, mostly noticed during physical activity
  • Group B: More noticeable symptoms like breathlessness during daily tasks, persistent cough, and fatigue.
  • Group E: Severe symptoms with frequent flare-ups and limitations in everyday life.
