I've been using Symbicort for about 2.5 years now, just one puff twice a day. I'm 25, and recently I had a spirometry test done. My FVC came out to be 85 and my FEV1 was 80. After taking a bronchodilator and retaking the test, there wasn't a significant change. My doctor mentioned that I might just be on the low side of normal, possibly with intermittent asthma or maybe nothing at all. But then I came across information suggesting that a lack of improvement in the reversibility test could point to COPD. So now I'm wondering, should I be concerned about COPD, or am I getting ahead of myself?
