When healthy people exercise, they may experience abnormalities that are similar to those seen in patients living with gastroesophageal reflux disease (GERD). This is particularly the case for people who run.
Researchers from the Academic Medical Center in Amsterdam recently conducted a study with 10 healthy and physically active people without GERD. They each had pH-impedance and solid-state high-resolution catheters inserted into the esophagus transnasally and then ate a meal and rested for 30 minutes. Next, they ran on a treadmill.
The findings showed that exercise led to a higher percentage of time with a pH of less than 4 in the esophagus compared to resting. Exercise also led to significantly longer duration and higher frequency of reflux episodes.
These findings were published in the American Journal of Gastroenterology on April 12, 2016.
