Due to wheezing, coughing, fatigue and related breathing issues I had a spirometry test and CT scan done in 2021. I was 31 with a history of asthma/GERD but otherwise active and healthy with no history of smoking. The tests came back as follows:
Pre
FEV1: 80% FVC: 85%. FEV1/FVC: 93%
Post
FEV1: 82%. FVC: 89% FEV1/FVC: 92%
CT scan showed a mosaic pattern attenuation with the likely cause being small airway disease.
I was told that it was likely the GERD causing the lungs to react and obstruct my breathing but the FEV1 being that low does concern me as it is on the border of abnormal and mild COPD. I've monitored it for the past few years with the same symptoms flaing up from time to time but it has gotten worse and more chronic over the past few months. I'm curious what others may think of these results and if there is any advice on how to advocate to the doctors that I believe this is a lung issue and not GERD based on the old results and persistent symptoms.
