What causes acid reflux?

When you eat, food travels from your mouth to your stomach via your esophagus. Your esophagus connects to your stomach by a circular band of muscles called the lower esophageal sphincter (LES). When you swallow, the LES relaxes to let food and liquids drain down into your stomach. After it closes up, this stops the acid from flowing back into the esophagus. But sometimes your LES becomes weak or relaxes when it shouldn't. This allows acid from your stomach to flow back into your esophagus -- or even into your throat and mouth.
