breathing issues and gluten intolerance?

For 2 1/2 years I have had breathing issues. I feel the need to take deep breaths and yawn literally every 2 minutes. It is becoming more and more difficult to just function. Sometimes I even struggle to get the breath that I feel I need. I have been told by 3 different ENT's that I have stomach issues yet seeing gastro Dr's they say my stomach is fine.

I can sometimes feel stomach acid coming up but no burning. I have tried everything I know to try,could this be a gluten intolerance? I gained a massive amount of weight(at least I think it's massive) the weight gain has been about 50-60 pounds and seems to be mainly in my gut. The weight came on fast,within 4 months.

The ENT's have ran cameras and say my airway above my vocal cords is swollen. A breathing test indicates upper air way obstruction which goes along with the swelling. Any advice would be helpful seeing as Dr's want me to have this very drastic surgery on my stomach called a Nissen.
