I'm having bariatric surgery in a few weeks. Please no one try to scare me or talk me out of it

I ballooned into 230 on a 5' 4'' body after being a 190, (which is way too much) but then taking a bunch of steroids for this eosinophilic asthma I developed. I started a new treatment for it 2 months ago and even though I am not completely well and I can't even walk around the block yet again I am better than I was.

I wanted this surgery for other reasons before, one being that I have been on every diet in the world and just can't get it to work. The other is damage to my back from falls etc that make it seriously painful to walk at this weight. Also GERD, which will be fixed with the gastric bypass that also contributes to asthma

But the other day I decided to type in "asthma and bariatric surgery" into Google scholar and got several responses. This one was very encouraging.

Results Bariatric surgery resulted in a profound weight loss at 12 months. In the BS+A group as well as the BS−A group FEV1, functional residual capacity, total lung capacity improved, whereas FEV1/FVC only improved in the BS−A group. In addition, Asthma Control Questionnaire (ACQ), Asthma Quality of Life Questionnaire, inhaled corticosteroid use and PD20 improved in BS+A, whereas in the NBS+A group only ACQ improved. Small airway function R5–R20 improved in both surgery groups, however the change in the BS+A group was greater, resulting in a comparable R5–R20 between BS+A and BS−A at 12-month follow-up. Besides improvement of systemic inflammation (high sensitivity C-reactive protein, adiponectin and leptin) after BS, only a decrease in mast cell numbers was detectable in the BS+A group.

Conclusions Bariatric surgery improved small airway function, decreased systemic inflammation and number of mast cells in the airways. These effects could explain the improvement of asthma control, quality of life and lung function. Therefore bariatric surgery, in addition to all other positive effects, also improves asthma in subjects with morbid obesity.

I watched a procedure which I cannot remember the name of on Youtube where they insert a tube into your lungs and use heat to open your airways. I noticed that the woman they were doing this to was very heavy and I wondered if anyone gave this information to her?
