What are the GOLD stages of emphysema?

ANSWER

Guidelines established by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) are based in part on how much air you can blow out of your lungs in 1 second, called FEV1.

  • Group A (GOLD 1 or 2): Your FEV1 is 80% or more. You might have had no flare-ups over the past year, or perhaps just one. You weren’t hospitalized for your symptoms.
  • Group B (GOLD 1 or 2): Your FEV1 is between 50% and 80%. You might have had one major flare-up, but you haven’t been in the hospital for your symptoms within the past year.
  • Group C (GOLD 3 or 4): Your FEV1 is between 30% and 50%. You’ve had more than two flare-ups in the past year, or you’ve been admitted to the hospital at least once.
  • Group D (GOLD 3 or 4): It’s extremely hard for you to breathe in or out. You’ve had at least two flare-ups in the past year, or you’ve been hospitalized at least once. Doctors call this “end-stage” COPD.
