Let me preface my post by stating that I'm a half pack a day smoker and have been since before the UC DX
Well, even slightly before DX I used to feel occasionally short of breath -
But every now and then now, definitely not all the time, I get shortness of breath and sometimes wheezing (which I never ever had)
I believe I read somewhere regarding the autoimmune condition AS that it can cause the ribs to tighten? Correct me if I'm wrong, sorry I don't have the time to double check that fact.
Anyway, this concerns me as well and I guess I will mention it when I get my next physical with the GP as my GI would probably just look at me.
