Gastroesophageal Reflux Disease affects about 20% of Americans (American Society for Gastrointestinal Endoscopy, 2020).GERD is primarily a disorder of the lower esophageal sphincter which contracts and relaxes to let food inside the stomach and to keep it from coming back into the esophagus (Clarrett & Hachem, 2018). However, food can also stick because the lower esophageal sphincter does not relax to let the food into the stomach (a disorder called achalasia – see below), or because the esophagus contracts in an uncoordinated way (a disorder called esophageal spasm). Dysphagia can cause food to back up in the esophagus. The esophagus is made of tissue and muscle layers that expand and contract to propel food to your stomach through a series of wave-like movements called peristalsis. Synchronized (peristaltic) contractions follow each swallow to accomplish this task. The opening and closing of the sphincter is controlled by peristaltic waves produced by the stomach during the digestion process. GERD occurs when stomach contents move back up the food pipe, causing discomfort. Between swallows, the esophagus usually does not contract. Symptoms may include: Vomiting Dysfunction of the gastroesophageal sphincter causes gastroesophageal reflux, which causes heartburn and if it happens often enough, can lead to gastroesophageal reflux disease, with damage of the esophageal mucosa.
