Hi Val - that's a good question - thanks for posting it! As you may be aware, COPD affects everyone differently. However, coughing, and sometimes productive coughing, can be a typical symptom of COPD. Symptoms can also change within stages for patients. When it comes to triggers, they too can vary among patients. It is difficult to tell what is causing the coughing in your particular case. Sometimes, coughing can be the result of a cold or allergy (in addition to COPD).
Do you have any thoughts about this? Is it something you would consider discussing with your physician?
In the meantime, I thought you might gain some additional insight from this article which focuses on COPD and coughing: https://copd.net/living/not-just-cough. I do hope you find the information is helpful for you.
All the best,
