If you have GERD, the lower esophageal sphincter
sometimes remains open, allowing acid to go up into the esophagus.
In addition, Carlson and Hirano (12) examined the complex mechanisms of reflux during running by new technology simultaneous high-resolution manometry, and pH-impedance in 10 healthy subjects after a meal, including transient lower esophageal sphincter
relaxation (transient lower esophageal sphincter
relaxation, aka "belch reflex") and transient formation of a hiatal hernia.
Functional and molecular analysis of L-type calcium channels in human esophagus and lower esophageal sphincter
Complete lower esophageal sphincter
relaxation observed in some achalasia patients is functionally inadequate.

(Figures 1 and 2) The lower esophageal sphincter
was lax as seen from the stomach.
Thick lower esophageal sphincter
in younger patients is suggested as cause of this poor response17.
Caption: Heartburn results when the lower esophageal sphincter
does not close properly, allowing stomach acid to flow back into the esophagus.
As showed, there were no significant differences (all p value > 0.05) in mean age, symptom duration, LESP (lower esophageal sphincter
pressure), IRP (integrated relaxation pressure), length of LES (lower esophageal sphincter
), and prior history of treatment between the two groups.
During an upper EUS examination, the thyroid gland is usually visualized close to the upper esophageal sphincter
. However, EUS is limited in visualizing the upper portions of the thyroid glands [4, 5].
The therapy directly targets the patient's weak or dysfunctional lower esophageal sphincter
muscle between the stomach and the esophagus, often the underlying cause of reflux.
