COPD Stage 1 (Mild) is where you want to catch the disease to be diagnosed. However, due to the lack of symptoms it often goes undiagnosed until a later stage. The main reason COPD Stage 1 symptoms go unnoticed is because according to GOLD guidelines, stage 1 COPD patients still have an FEV1 of 80% or higher. A lot of times, patients can attribute their COPD symptoms to a few different things including:
- Old age
- Getting a cold
So rather than going to the doctor to see if anything is wrong, these symptoms get written off as something minor.
