@stew80 after a couple of years fighting with doctors on why I have a shortage of breath finally a doctor did a drug induced stress test. What was found was durning normal everyday routines everything was great, as soon as my heart became under stress stairs, carring groceries, cold weather lots of other situations my heart ejection fraction went from 55 percent down to 42 to 44 percent and that's why I have shortage of breath. Nothing they can because of heart attacks and open heart surgery heart muscle is basically dead. Hope that helps.

@stew80
Thank you for your reply. What a dilemma, huh?
I am of normal stature and have never been told that i have 'big lungs' So we do not share those things - the air hunger, we do.
My best to You and hope we can find a solution!

@stew80 You’re definitely not alone in wondering about body type and anatomy. I’ve heard the “big lungs” comment before too, and frustratingly, it’s usually said without much explanation about what it actually means or whether it matters. Being thin or having a larger lung volume doesn’t seem to give doctors a clear answer, but a lot of people here with very different body types report the same air hunger sensation, which makes it even more puzzling.

I’m curious, have you noticed whether your symptoms are more pronounced at rest versus during activity? And when you were told you had “big” lungs, was that based on pulmonary function testing, or just an offhand comment? Sometimes those little details help connect patterns across stories.

Thanks for chiming in. The more people speak up, the clearer it becomes that this is a real, shared experience, even if medicine hasn’t caught up yet.
