“Carbonated beverages cause gastric distension,” said Dr. Daniel Mausner, section head of gastroenterology at Mercy Medical Center in Rockville Center, N.Y. “And if your stomach is distended, this increases pressure on the esophageal sphincter, promoting reflux.”
Mausner told WebMD that people with heartburn may be wise to steer clear of sodas and other carbonated beverages.
Irritable bowel syndrome
In a study published in the World Journal of Gastroenterology, among the many diet recommendations for those with irritable bowel syndrome was avoiding carbonation.
“Water and other non-caffeinated drinks, for example, herbal teas, are recommended as a beverage for patients with IBS,” according to the study. “In contrast, carbonated water and other carbonated beverages should be avoided by IBS patients, because they may cause symptoms. One study reported more [gastrointestinal] symptoms from carbonated beverages among IBS patients compared with controls.”
Although studies have found carbonated water to be no more harmful to teeth than regular water, getting your fizz from sugary drinks can be harmful.
“Sparkling water brands with added sugar can no longer be considered just sparkling water,” Mouth Healthy wrote. “They are a sugar-sweetened beverage, which can contribute to your risk of developing cavities. So remember — sparkling or not — plain water is always the best choice.”
