GERD is very common, because of years of high pressure endured by the lower esophageal sphincter. Often people with R-CPD get told the primary diagnosis is acid reflux, when acid reflux is only one of the symptoms of R-CPD.Keep in mind that symptoms of R-CPD are “all” GI, rather than at the cricopharyngeus muscle itself. So if gurgling, bloating, hiccups, are present even with ability to burp, consider the idea of not inability, but ‘insufficiency’ of burping where air out (via burping) is less than air in.
