GERD & Heartburn Support Group
Gastroesophageal Reflux Disease (GERD) is defined as chronic symptoms or mucosal damage produced by the abnormal reflux of gastric contents into the esophagus. This is commonly due to transient or permanent changes in the barrier between the esophagus and the stomach. If you are afflicted with GERD or heartburn, join the group and find support.
