Hello Patti1962 .
I have RA and Bronchiolitis Obliterans. Just so that I'm clear, were you diagnosed with BOOP , Bronchiolitis Obliterans Organizing Pneumonia ? BOOP and BO share half the same name yet prognosis is quite different. BOOP is it seems is treatable and most patients recover with corticosteroid therapy. BO is not and often requires lung transplantation. May I ask what kind of cancer you were screened for?
The bloating could well be from the steroids. I too am bloating and gained eight pounds over the couple of years I have been on steroids. My pulmonologist has assured me once I go off them I should be able to lose the weight. Do you know exactly how much weight you have gained? If you have gained a significant amount this should be taken up with your doctor. And any underlying causes other than the steroids should be ruled out, just to play it safe. I understand how uncomfortable this extra weight is. I absolutely hate it and try and keep as active as possible. Yesterday I went out and bought a rather shapeless loose dress because my tight jeans are no longer practical. They just make it harder for me to breathe.
As for your last question I am sorry I don't quite understand. If you have had a lung biopsy the doctor should know if you have fibrosis or not.
I'm sorry I'm not more helpful. But I'd like to be supportive. I know how awful the pain, fatigue, swelling and breathlessness is.
Thinking of you.
