Exercise-Induced Reflux: Why Workouts Can Trigger GERD
Can Exercise Actually Cause Acid Reflux in Healthy People?
Yes, exercise can induce gastroesophageal reflux even in healthy individuals without pre-existing GERD, particularly during high-intensity activities that increase intra-abdominal pressure or involve jarring movements. This exercise-induced reflux occurs through mechanical compression of the stomach, altered gastroesophageal junction positioning, and changes in gastric emptying patterns during physical activity.
Dr. Kumar’s Take
This research explains why many people experience heartburn during or after workouts, even if they don’t normally have GERD. Exercise creates a perfect storm for reflux - increased abdominal pressure squeezes the stomach, bouncing movements jostle gastric contents, and altered positioning can compromise the anti-reflux barrier. Understanding these mechanisms helps athletes and fitness enthusiasts modify their routines to minimize symptoms while maintaining their exercise goals.
