Unusual spirometry results—looking for experiences or insights

Hi everyone,

I am a 27-year-old male. About nine months ago, I started noticing changes in my breathing. The change was quite drastic—one moment I felt normal, the next I was struggling—and it hasn’t gone away.

It took a few months and visits to several doctors before I saw a pulmonologist. Currently, I have better days and some worse days, but since the very first day, I haven’t had a truly normal day.

From what I understand, everything else on my spirometry looks normal, but we are unsure why my RV is elevated. I am currently using Sereflo and Budeflam as prescribed.

I have had three spirometry tests so far:

1. First test: My RV was 171% of predicted. My doctor prescribed Sereflo, Budeflam, and antibiotics, and we rescheduled for two weeks later.
2. Second test (after 2 weeks): My RV had decreased from 171% to 147%. Both my doctor and I thought this was a good response and decided to continue the treatment for three more months.
3. Third test (after 3 months of inhalers and antibiotics): My RV increased again to 161%.

I will attach my latest spirometry results. Let me know if the first two tests would also be useful for context, and I can add them.

Any insights or experiences you could share would be greatly appreciated.
