Acid reflux is an uncomfortable condition that happens when the valve that connects the esophagus and stomach is weakened, allowing stomach acid to flow back up into the esophagus. Acid reflux often feels like a painful burning sensation in the back of the throat or chest. Certain dietary restrictions may alleviate the pain associated with acid reflux. Carbonated beverages are shown to cause acid reflux symptoms because the bubbles expand in your stomach, pushing stomach acid and contents back up the esophagus. When experiencing acid reflux, it's best to consider whether sparkling and carbonated beverages affect your symptoms. Many health care professionals recommend skipping these drinks if you have GERD; however, research suggests that there is no evidence to support that carbonated beverages exacerbate or promote GERD.
