| 1 | Gastroesophageal reflux in asymptomatic obese subjects:An esophageal impedance-pH study显示文摘AIM:To investigate the relationship between reflux and body mass index(BMI) in the asymptomatic obese population using the impedance-p H technique.METHODS:Gastroesophageal reflux is frequent in the obese population.However,the relationship between acid reflux and BMI in asymptomatic obese people is unclear.Forty-six obese(BMI > 25 kg/m2) people were enrolled in this prospective study.We evaluated the demographic findings and 24-h impedance p H values of the whole group.Gas,acid(p H < 4),weak acid(p H = 4-7) and weak alkaline(p H ≥ 7) reflux parameters were analyzed.RESULTS:The mean age of patients was 49.47±12.24 years,and half of them were men.The mean BMI was 30.64±3.95 kg/m2(25.14-45.58 kg/m2).BMI of 23 was over 30 kg/m2.Seventeen patients had a comorbidity(hypertension,diabetes mellitus,or ischemic heart disease).Endoscopic examination revealed esophagitis in 13 of the 28 subjects(10Grade A,3 Grade B).The subjects were divided into two groups according to BMI(<30 and>30 kg/m2).Demographic and endoscopic findings,and impedance results were similar in these two groups.However,there was a positive correlation between BMI and total and supine p H<4 episodes(P=0.002,r=0.414;P=0.000,r=0.542),p H<4 reflux time(P=0.015,r=0.319;P=0.003,r=0.403),and De Meester score(P=0.012,r=0.333).CONCLUSION:Acid reflux is correlated with BMI in asymptomatic obese individuals. | Filiz Akyüz Ahmet Uyanikoglu Fatih Ermis Serpil Arici ümit Akyüz Divison of Gastroenterology Department of Internal Medicine Faculty of Medicine Yeditepe University Bülent Baran Binnur Pinarbasi Nurdan Gul | 2015 | World Journal of Gastroenterology2015，21，10： | 3 |
