Heartburn and Gastroesophageal Reflux Disease (GERD). The stomach releases strong acids to help break down the food. If the esophageal sphincter opens too often or does not close tight enough, stomach acid can reflux or seep back into the esophagus, damaging it and causing the burning (heartburn). Valve vectors
