GERD / Acid Reflux
Gastroesophageal Reflux Disease, or GERD, is a digestive disorder that affects the ring of muscle between the esophagus and the stomach. This muscle ring is called the lower esophageal sphincter (LES). It opens to allow food to pass into the stomach and closes to keep the food and stomach acids from refluxing back up into the esophagus. When the LES doesn’t work properly, the acids burn the esophagus and can cause ulcers, bleeding and scarring.
