Hi. I have asthma where I use supplimental oxygen 24/7. Just resting, I barely need it, but when I do anything I need it. I'm seeing my surgeons PA next month, after a long absence to see if I can get my band removed and go RNY. I'm 365, 5'4". BMI in the low sixties.

My question...Can you have gastric bypass when you need to use oxygen?

I don't know the answer to your question, but I think I saw individuals on oxygen in the bariatric ward after my operation. So I think the answer is yes. But if you are on oxygen 24/7, it will be very difficult for you to get your walking exercise in.

I have suffered with asthma my entire life. I generally used a rescue inhaler (ProAir) around 10 times per day. When I went in for my final pre-op exam, the doctor recommended that I transition off the rescue inhalers to Advair. I followed her advice and now I take one puff in the morning and one at night and extremely rarely every use my rescue inhaler. I am 16 months post-op RNY at this point.

Also during the pre-op testing, they discovered a huge growth in one of my lungs. It was the size of my fist. It was calcified, so no danger from cancer. It is probably one of the reasons why breathing has been difficult for me during my lifetime.
