Influence of Acute Mental Stress on the Frequency and Duration of Gastroesophageal Reflux in Normal Volunteers
Six fasted healthy male volunteers (mean age 21.7 years) were studied. A pH probe was inserted with the tip 5cm proximal to the gastroesophageal junction and recording begun 15 mins after completion of a standard meal. pH was recorded by computerized data logger which sampled every 6s.

| description | Six fasted healthy male volunteers (mean age 21.7 years) were studied.
A pH probe was inserted with the tip 5cm proximal to the gastroesophageal junction
and recording begun 15 mins after completion of a standard meal. pH was recorded by
computerized data logger which sampled every 6s. Subjects were stressed intermittently
by a dichotic Listening task in which they attempted to track recorded word Usts heard
simultaneously in different ears. Mean frequency and duration of reflux episodes was
determined from two 30-min stress and control periods. Alterations in heart rate, systolic
and diastolic blood pressure confirmed the effectiveness of the stressor. Mean ( ± SEM)
duration of reflux per 30-min stress period ( l . l ±0.53 mins) was not significantly different
to mean duration per 30-min control period (l.5 ±0.53 mins). The mean numberof
reflux episodes per 30-min stress period (2.3 ± 1.1) did not differ significantly from the
mean number of episodes per 30-min control period (2.8± 1.1). T herefore, in normal
volunteers acute predictable emotio nal stress does not influence the frequency or duration
of postprandial gastroesophageal reflux. |
