I too have a hiatal hernia & IBS. Last week I woke up with terrible stomach pain and went to the bathroom feeling likei needed to poop. My heart was racing, I was sweating & felt like I was going to vomit because my mouth was watering. I bent over to spit in the trash can & passed out and fell off the toilet. When I woke up my son was knelt down beside me on the phone with 911. Went to ER and they said I had vasovagal syncope & gastroenteritis. I did have a very large BM in the ER (very embarrassing) & felt relief. I was weak & a bit shaky for the next few days.
Hi and welcome to the GERD forum.
Yes, GERD, and or acid refflux ca cause chest discomfort, even heart palpitations......and mimic a heart attack...which is why it was wise to have your heart looked at and ruled out.
The vagus nerve can be affected which can cause the chest discomfort and heart palps....
and with a hernia it can affect the diaphragm which can affect the breathing end of your symptom....do you know if your hernia is a sliding one?
