ABSTRACT
Abstract  A previous study showed that supine gastroesophageal reflux occurs mainly in the early nighttime period and is greater if the patient retires within 2 hr of a meal. We analyzed 306 consecutive esophageal pH studies between January and July 2003. Ninety-two patients had abnormal supine reflux. The recumbent period was divided into quarters (Q1–Q4) and reflux parameters were calculated for each period. Reflux was maximal in Q1, and decreased progressively from Q1 to Q4 (PP=0.012), but no increase in reflux was observed in those retiring within 3 hr. Supine reflux occurs maximally in the early nighttime period. Although not fully explained as a postprandial phenomenon, these patients should avoid going to bed within 3 hr of a meal.
