Popis: BACKGROUND Currently, it has been demonstrated that gastroesophageal reflux disease (GERD) is one of the most important disorders of the digestive system and the commixture of regular diet has a significant influence on its incidence, symptoms, and prognosis. The purpose of this study was to evaluate the effect of zinc supplementation, in combination with PPIs(Proton pump inhibitors), on the improvement of GERD symptoms. METHODS In a randomized double blind clinical trial, patients with reflux symptoms, who had obtained Reflux Disease Questionnaire (RDQ) score more than 8, were included and all the demographic features were recorded. Then, using upper gastrointestinal (GI) endoscopy, all the patients were divided into two groups as having non-erosive reflux disorder (NERD),or erosive reflux disorder (ERD). At the next step, based on random block statistical method, we divided the two groups into two subgroups; the drug subgroup [treated with PPIs (40 mg pantoprazole/daily), changing life style, and 220 mgzinc capsules daily] and the placebo subgroup [treated with PPIs, changing life style, and placebo]. After 3 months, we analyzed all data and the RDQ questionnaire was filled out for each patient. This project has been registered in Iranian Registry of Clinical Trials (IRCT) and all data were analyzed using SPSS software version 2. RESULTS A total of 140 patients (81 women and 59 men) with mean age of 42.78±11.5 years were included with 70 patients in each group. The most frequent presentations were heart burn (45.7%), and acid regurgitation (39.3%). The RDQ scores decreased after intervention in both drug (p
