#GITwitter, #MedTwitter, after enjoying a hearty meal, it feels appropriate to do a #tweetorial on belching.
Belching is common, yet it is what one of those symptoms that are often ignored
So how do we evaluate and mx belching?

Belching affects quality of life, as excessive belching can disrupt social lives https://journals.lww.com/eurojgh/Abstract/2010/12000/Impaired_health_related_quality_of_life_in.5.aspx
Up to 50% with dyspepsia have belching40-49% GERD pts have belching, and pts with belching
severe GERD sxhttps://pubmed.ncbi.nlm.nih.gov/19455107/
So we need to help them

2 types of belching, differentiated with esophageal impedance studies
The first (on the left) is typical gastric belch that we get after a gassy drink due to reflex from gastric distension
Dotted lines show air direction from stomach (distally) to esophagus (proximally)

The second belch (on the right) is a supragastric belch (SGB)
Air is seen to be swallowed first, dotted lines moving from esophagus (proximal) to stomach (distal), and then belched out. It doesn't originate from stomach, but rather esophagus and hence termed supragastric

SGB can be associated with GERD with more SGB being symptomatic than gastric belching & more reflux episodes associated with SGB
On the picture on the right, the pH in the distal esophagus (bottom row) dropped as the SGB occurred, demonstrating SGB inducing GERD

Qns to look in the history
predominant sx (since belching can be sx of conditions causing dyspepsia)
chronology of sx (did the belch cause reflux or vice versa)
clues to suggest SGB = anxious personality, distractability, rapid, repetitive, "aura" prior to belch

Once endoscopy is done and is normal, and esophageal physiological studies show supragastric belching, what would you try?

We did prospective study using waitlist controls @AGA_CGH and showed diapragmatic breathing (DB) improves belching, GERD sx and QoL after rx and 4 months post rx

How does DB work?
Abolish air swallowing. Try opening your mouth and swallowing air. You can't. Without air swallowing, you can't do a SGB
Strengthen the crura. This may rx GERD due to barrier issues independent of belching
Relaxation technique. May stimulate vagus

Conclusions:
Belching has 2 types (gastric, supragastric)
The hx can distinguish but impedance testing often needed
Treat primary causes of dyspepsia if any
Give DB a try, especially for SGB
A subset of refractory GERD have SGB and hence treatable w/o PPI
