I am 33s man. I was smoking occasionally between 20-27s. I practiced sport until I was 30 years old (triathlon). After COVID in 2021 I felt that my physical capacity slightly decreased and never improved. I explained it by not training anymore. After second COVID in January 2023 I felt that my breathing was even worse, and it has stayed until now. No cough and phlegm.
At the end of January 2023, I did a spirometry with the following results:
FVC: 5,92 (117%)
FEV1: 4,34 (104%)
FEV1/FVC: 75%
PEF: 9,74 l/s (113%)
The doctor said that everything is ok. I was still having problems so I was looking for a solution. I've been to several pulmonologists and none of them saw or heard anything alarming.
In March 2023 I did another spirometry (in a professional clinic) with the following results:
FVC: 6,11 (115%)
FEV1: 4,07 (94%)
FEV1/FVC: 67%
PEF: 12,20 l/s (127%)
after sulbutamol:
FVC: 6,10 (115%)
FEV1: 4,13 (95%)
FEV1/FVC: 68%
PEF:12,86 l/s (134%)
In June 2023 I did another spirometry (also in a professional clinic) with the following results:
FVC: 6,19 (117%)
FEV1: 3,71 (85%)
FEV1/FVC: 59%
PEF: 11,72 l/s (123%)
after sulbutamol:
FVC: 6,23 (117%)
FEV1: 3,93 (91%)
FEV1/FVC: 63%
PEF:12,44 l/s (130%)
DLCO: 40,56 (119%)
KCO: 5,50 (114%)
VA SB: 7,38 (107%)
Hb: 14,60 (100%)
TLCO: 7,70 (109%)
RV: 1,64 (89%)
RV/TLC: 21,35 (82%)
FRC: 4,52
VC: 6,06 (109%)
ERV: 2,88 (173%)
IC: 3,18 (83%)
ergospirometry is ok (SPo2: 98% before, and 96,8% after excersise, based on gasometry)
I also did HRCT but it showed no significant changes (only minor fibrosis in the tops of the lungs (probably a history of asymptomatic tuberculosis).
Can anyone know what's going on? I have read that it can be mild COPD 🙁
