Wearing a back support belt does not increase gastroesophageal reflux (GER) in healthy individuals. Studies show no significant changes in lower esophageal sphincter pressure or reflux episodes when using a back support belt.

Area of Science:

  • Gastroenterology
  • Physiology

Background:

  • A competent lower esophageal sphincter (LES) is crucial for preventing gastroesophageal reflux disease (GERD).
  • Increased intra-abdominal pressure can challenge LES competence.

Purpose of the Study:

  • To investigate whether wearing a back support belt induces gastroesophageal reflux (GER) in healthy volunteers.
  • To assess the impact of back support belts on lower esophageal sphincter pressure (LESP) and reflux parameters.

Main Methods:

  • Esophageal manometry was used to locate the LES in ten healthy volunteers.
  • Two 8-hour intra-esophageal pH monitoring studies were conducted per subject: one with and one without a back support belt.
  • Symptom diaries and pH data were collected throughout both study periods.

Main Results:

  • Mean LES pressure (LESP) showed no significant difference with or without the back support belt (14 ± 3.6 mm Hg vs. 15.8 ± 4.3 mm Hg).
  • No significant differences were observed in total GER episodes, esophageal acid exposure, or other monitored parameters.
  • Subjective GER symptoms remained consistent between the two study conditions.

Conclusions:

  • Healthy individuals with normal LESP do not experience increased GER when wearing a back support belt.
  • Back support belts do not appear to compromise LES function or exacerbate reflux in this population.
