Soda Before Bedtime Raises Reflux Risk
(HealthDayNews, 5/10/05)

Dr. Ronnie Fass of the University of Arizona, Tucson, and team, analyzed data from more than 15,000 participants in the ongoing Sleep Heart Health Study. The investigators found a link between consuming carbonated beverages near bedtime and severe nighttime heartburn. They theorize that the carbon dioxide in these beverages may cause stomach distension, which contributes to this condition. They also found a relationship between the regular use of sedatives containing benzodiazepines and heartburn, which they say occurs because such drugs may weaken the barrier between the esophagus and stomach. The researchers note that acid reflux during sleep is particularly damaging because the acid may lay in the esophagus longer. The scientists recommend not drinking soda late in the day and, where appropriate, changing sleep medications.
