@gabrielm- Shortness of breath, also called dyspnea, occurs with GERD because stomach acid that creeps into the esophagus can enter the lungs, particularly during sleep, and cause swelling of the airways. ... Such airway damage can affect breathing by causing coughing or wheezing.Jun 27, 2017"

Me too brother.. just like you!

Hello HOPING this gets to the right people and maybe expert ???
don't know if this will get to the right people or doctors, BUT !!
I have had a cough for over ten years,mostly after eating, no pain and then it gets under control, it started with having a bad cold or bronchitis and each time it took longer to get rid of the cough, also when I exercise causes "fatigue and shortness of breath! never had pain , eventually went to pulmonary doctor, extensive tests, showed no asthma , clear lungs, etc. then "google" said it could be heart related, had not been to a cardiologist in many years ( have always been an athlete,but in getting older, slowed down, but love sports, still fatigue and shortness of breath and severe cough. then doctor sent me to an allergist, blood work showed no allergies, except to bahia grass !!?? what NONE around here. SO, this young,brilliant cardiologist did 6 tests ( even though I told him I hoped I was there for a "wellness" test to eliminate any heart issues ( which caused cough ???) and on the 6th test ( he must have suspected something and didn't give up !!WOW !! a cardiac catherization exposed a triple blockage, needless to say I was shocked -so open heart surgery (which is overwhelming but HE saved my life ! and he is only 36 yrs. old - a genius in my opinion ) and so I recovered in 8 wks, back to tennis /pickle ball (in moderation of course
and THEN !! the cough came back. SO, I took myself to a gastro doctor ,endoscopy showed a hiatal hernia ( gave me photos of it ) ,then had to find a surgeon who does hiatal hernia surgery ( not many ) and he said yes, I feel I can fix your cough, but first I require two more tests with another gastro dr. called Manometry and a Bravo test, done separately under anethetic. After those tests this gastro dr. said he did not see any hiatal hernia !! so now I do not know what to do !!! sure don't want surgery, and have not heard back from the surgeon as of now !!! In hearing about all the complications of people of have had the surgery and then other worse complications, I am thinking I will live with this cough, although I would like to exercise longer (playing sports) without fatigue and shortness of breath !! I "think" and this is my own laymans opinion, however one knows ones body !! - that my fatigue and shortness of breath is caused by the supposedly or not !! Hiatal hole between lungs and esophagus somehow causing this "leakage of breathing ?? !!!!
