About

Gastroesophageal reflux disease is increasing worldwide. The causes of reflux symptoms are not found exactly. especially, the postprandial reflux symptoms are more common than the all day reflux symptoms. One of the causes of reflux symptoms is the relaxation of the lower sphincter of the esophagus. But, the sphincter relaxation also occur in normal people. But, there is a difference in postprandial reflux pattens between the patients and the normal people. So, in this study, we want to compare the difference of reflux pattern between the patients who have postprandial reflux symptoms and normal people though the 24hr pH monitoring.

Description:

Esophageal pH monitoring is the current gold standard for diagnosis of gastroesophageal reflux disease. It provides direct physiologic measurement of acid in the esophagus and is the most objective method to document reflux disease, assess the severity of the disease and monitor the reflux acidity.
