What is another word for gastroesophageal reflux?
Pronunciation: [ɡˈastɹɪsˌɒfəd͡ʒˌi͡əl ɹˈiːflʌks] (IPA) 
Gastroesophageal reflux disorder (GERD) is a digestive disorder that causes the stomach's contents to flow back into the esophagus. This condition is also known as acid reflux. Some other synonyms for gastroesophageal reflux include heartburn, acid indigestion, and sour stomach. GERD occurs when the lower esophageal sphincter (LES) muscle, located at the bottom of the esophagus, does not close properly. This can lead to symptoms such as chest pain, difficulty swallowing, and regurgitation. Other less common synonyms for GERD include pyrosis, acid regurgitation, and water brash. If left untreated, GERD can lead to serious complications, such as esophageal cancer, so it is important to seek medical attention if symptoms persist.
