Reason for reduced lung function?

For past few months I noticed I wasn't able to exercise as much as usual. So I had a lung function test in February which showed dclo 69%. I am 49 year old fit non smoking lady. I had a CT scan two weeks ago which showed no scarring on lung or cause for reduced dclo. So respiratory consultant said to redo CT scan in 6 months time. I have diabetes type 1 and MS. I had immunosuppressant treatment for MS last September and am due round 2 in September of this year. Now I don't know where this leave me going forward as I have never had a lung function test so don't know if it is caused by the immunosuppressant or something I have always had?

Hi the important figure is your FEV1 (your lung function). What does that say? What did they diagnose as the cause?

I don't know anything about your other illnesses so can't say if they can cause this. Your best bet is to ring your doctor or consultant and ask x

My initial letter after lung function just said normal spirometer parameters, dclo reduced at 69.5% and KCO 75.3%. His secretary told me the result of the CT scan over the phone but also said she had sent me a letter today so that might give more info. Nobody has mentioned a cause.

I haven't a clue what dclo or KCO means. But it sounds like you don't have a lung problem. x

Thank u. That's what I'm thinking too. One less illness to worry about.

Can’t help with the spirometry results, I’m afraid, and I’m by no means particularly well versed in MS, but the thought crossed my mind that perhaps your breathing and ms could be linked? As I understand it, MS can effectively impact any muscle system in the body (amongst other things), and there is significant muscle involvement in breathing triggered by our autonomic nervous system. It might be an avenue for you to research and look in to at least if there is no obvious respiratory cause?

DLCO (Diffusing Capacity of the Lung for Carbon Monoxide) is an indication of the rate of transfer of CO in the air of the lung into the pulmonary capillary blood. ... A number of pathological states can affect DLCO (e.g., anemia, pulmonary ...

Thanks. So it's not necessarily the lung that's causing the reduced DLCO?

That’s correct other body organs can influence how well our lungs work it just that it’s only our lungs that can put oxygen into our blood. Good in-depth information can be found at British Lung Foundation, NHS choices and other good reliable websites.
