Gastroesophageal reflux disease, or GERD, occurs when the lower esophageal sphincter (LES) does not close properly and stomach contents leak back, or reflux, into the esophagus. The LES is a ring of muscle at the bottom of the esophagus that acts like a valve between the esophagus and stomach. The esophagus carries food from the mouth to the stomach.

An antacid is any substance, usually a base, that counteracts stomach acidity. It is taken by mouth to relieve heartburn, sour stomach, or acid indigestion. Most antacids buffer gastric acid, raising the pH to reduce acid damage. If antacids are ineffective, medication (H2-receptor antagonists or proton pump inhibitors) may relieve the symptoms. Poor response to medication may be a reason to suspect an underlying medical condition.
