impact of weight loss on gastroesophageal reflux disease in overweight and obese subjects: a prospective study

Conditions: GERD; Obesity

Summary: by affecting the gastroesophageal pressure gradient, obesity predisposes to reflux of gastric contents. the investigators hypothesized that the loss of weight will decrease this gradient and as a result decrease the severity and frequency of gerd symptoms. gerd negatively affects health related quality of life. since loss of weight may decrease gastroesophageal reflux, the investigators hypothesized that it obesity contributes to poor quality of life in gerd subjects and losing weight should also favorably impact and improve quality of life in gerd patients.

the current proposal is a prospective, observational cohort study this study aims to determine the impact of structured weight loss (move program) on gerd symptoms in overweight and obese veterans enrolled in a move program. successful weight loss will be defined as loss of 10% or higher baseline weight at 6 months follow up. cases will be defined as subjects who achieved successful weight loss and controls as those who did not. gerd symptoms in subjects who lose weight (cases) will be compared to those with no weight loss (controls). validated gerq, rdq and qolrad questionnaires will be used to assess prevalence of gerd symptoms, qol and impact of weight loss on these symptoms. all move participants will complete a validated gerq, rdq and qolrad questionnaires at baseline move clinic visit and rdq and qolrad during their follow up visits. patient's total rdq scores at baseline and follow up visits will be used to determine change in frequency and severity of gerd symptoms with weight loss, similarly change in the total qolrad questionnaire scores from baseline will be used to assess change in hrqol with weight loss. apart from information provided in move!23, gerq, rdq and qolrad questionnaires, relevant information pertaining to obesity and gerd association will be obtained from patient's computerized medical records. the impact of weight loss on gerd symptoms will be assessed. the impact of weight loss on qol and gerd medication usage among move participants will be assessed.
