Acid reflux happens when stomach contents move back up into the esophagus[1]. When reflux becomes frequent, persistent, or leads to ongoing symptoms or complications, it may be diagnosed as gastroesophageal reflux disease, or GERD[2]. Many people know acid reflux by symptoms such as heartburn, regurgitation, and upper digestive discomfort. Canada Drugs Online helps Americans browse prescription acid reflux medications more easily while giving them clear information about reflux, GERD, and prescription access.
