If the LES stays
open, which can happen if you have a paraesophageal hernia or just a weak LES, the acid can leak into the esophagus if you recline or lie down. For 25 years I was able to combat this successfully by simply taking enough PPIs to keep my stomach non-acid. This also serves to keep down irritation and the resulting to the esophagus.
Did your doctor say whay TYPE of hernia you have? Sliders don't usually cause problems all by themselves. Paraesophageals are stuck in the chest and must be surgically brought down to avoid stomach strangulation. My little slider was traumatically pushed into my chest by my seatbelt in a high speed crash, causing me to need surgery, during which I also got a fundoplication which stopped the reflux.
LPR just means the acid is reaching the larynx. The best test for seeing how high the acid goes and to see what kind and size of the hernia is the barium swallow. It's non-invasive, doesn't hurt at all. Docs can't see everything lying down for a scope, and a lot of people need sedation!
The spasms can be caused, without reflux, just by food allergy/intolerance. Just keeping a food log is free, non-invasive, and your GI won't tell you to do it because they mostly don't know about
it. But a really top allergist does know about
this stuff!! Sure it takes time. I spent two months working on it! But it was the most worthwhile thing I did for myself and stopped the spasms and tachycardia/arrhythmias. You can't depend on doctors to everything for you. Each one is so specialized nowdays that they don't see the whole person. I left this disease go for 25 years, so I had some suspicions about
what was triggering the spasms. My GI doc poo-pooed me, didn't believe me even when confronted with the log I kept and the disappearance of the spasms when I avoided my triggers. I even went in with the scientific papers! But my allergist did believe me!!!!!
I had similar symptoms to yours: the spasms relieved by a burp. I let mine go for several years until finally I had a heart attack brought on by eating a bowl of cereal. OK, I certainly had a bit of cholesterol plaque in my coronary arteries, but the trigger was a spot spasm in an artery causing a plaque rupture in just that tiny spot. This is not an unknown happening! I recently read a medical article describing just this thing - although they didn't mention anything about
the food trigger, just the esophageal spasm starting the artery spasm.
I spent hundreds of hours scouring the internet reading about
spasms and reflux. It was well worth the time!!
Interesting note: Since my fundoplication and ability to allow my stomach to return to its normal acid state, I now tolerate a lot more of my food triggers. I read in a post by another person here that his food intolerances started when he went on PPIs. Mine was so long ago that I don't remember. I only know that I was not born with these food intolerances.
