Shift work is significantly and positively associated with possible gastro-esophageal reflux disease: A meta-analysis study
Summary
This meta-analysis reviewed 4 observational studies that compared reflux symptoms in shift workers and day workers. All studies relied on questionnaires to measure possible gastro-esophageal reflux disease (GERD). When combined, the results showed that shift workers were more likely to report GERD symptoms than day workers. Rotating shifts showed the strongest association, followed by permanent night shifts. The pattern appeared across both male-only groups and mixed-gender groups, suggesting the link applies broadly.
Why It Matters For Night Shift Workers and Night Owls
For night workers, this research confirms that heartburn and reflux symptoms are more common on shift schedules than during daytime work. Rotating shifts, where hours change frequently, appear to carry the highest risk. While this study didn’t test why, it adds to evidence that digestive discomfort is part of the shift-work health burden. Recognizing reflux as a common issue means workers and employers can treat it as more than an isolated complaint, and ensure that gastrointestinal health is considered alongside sleep and fatigue in shift-work planning.
