Background: Previous studies suggest that elevated levels of estrogen and progesterone, either through endogenous or exogenous sources, increase gastroesophageal reflux. Methods: To evaluate the relationship between symptoms of gastroesophageal reflux disease (GERD) and postmenopausal hormone (PMH) therapy, including the use of selective estrogen receptor modulators and over-the-counter (OTC) hormone preparations, we performed a prospective cohort study of 51 637 postmenopausal women enrolled in the Nurses' Health Study who provided data on the use of PMH therapy biennially since 1976, and information about symptoms of GERD in 2002. Results: Among eligible participants, 12 018 women (23%) reported GERD symptoms. Compared with women who never used PMHs, the multivariate odds ratio (OR) for the risk of GERD symptoms was 1.46 (95% confidence interval [CI], 1.36-1.56) for past hormone users, 1.66 (95% CI, 1.54-1.79) for current users of estrogen only, and 1.41 (95% CI, 1.29-1.54) for current users of combined estrogen and progesterone. The risk of GERD symptoms increased significantly with increasing estrogen dosage (P<.001) and increasing duration of estrogen use (P<.001). Moreover, current selective estrogen receptor modulator users experienced an OR of 1.39 (95% CI, 1.22-1.59) for GERD symptoms, and women currently using OTC hormone preparations had an OR of 1.37 (95% CI, 1.16-1.62). Conclusions: Postmenopausal use of estrogens, selective estrogen receptor modulators, or OTC hormone preparations is associated with a greater likelihood of symptoms of GERD. This suggests a hormonal component to the pathophysiologic characteristics of GERD in women.
