Well the last sentence you wrote is just flat wrong, wrong, wrong. Surgeons’ noses should grow when they say that. I will say when I am sitting calmly in a chair, I test almost 😅 Normal on pulmonary function. But I am absolutely short of breath easily - lifting my mattress corner to change sheets, bending over to dust baseboards, walking with virtually any incline, lifting anything, sweeping - all will have me gasping and my heart rate above 120. And I use that little device they gave me to use. Again, sitting calmly I’m golden. And I still have rib and diaphragm pain when I try to take a deep breath.

Now to be fair I am 73 and a tad overweight. But I was old and chubby before the surgery too. 🙂

Not trying to scare you. I’m managing and I’m sure you will too. I’m just trying to share my reality. I don’t think I’m alone in that experience. It shouldn’t prevent you from surgery if that’s the recommendation at some point. But just go in with eyes wide open.
