You would need extensive blood work, so I'd ask for specifics. High iron in the blood can suppress co2. Test that, co2, thyroid, and stress hormones specifically.

Breathing in a brown lunch bag allows you to retain co2, thus increasing it. o2 displaces co2 so at higher altitudes more co2 is retained due to lower oxygen pressure. These are good ways to test if you're possibly hyperventilating. I know that, when I was, I found I breathed much, much better in the mountains, so I worked on increasing co2 through breathing in a brown bag. Now I do this a few minutes each day, it sounds whacky, but it really helps.
Are you comfortable breathing through your nose, or is it difficult? Can be a sign of high lactate if this is the case.

I took the stars from our eyes, and then I made a map
And knew that somehow I could find my way back
Then I heard your heart beating, you were in the darkness too
So I stayed in the darkness with you
