GERD stands for Gastroesophageal Reflux Disease. It is a chronic condition in which stomach acid flows back into the esophagus, causing symptoms such as heartburn, regurgitation, chest pain, difficulty swallowing, and respiratory symptoms. If left untreated, it can lead to complications over time
. The main cause of GERD is the weakening or relaxation of the lower esophageal sphincter, which is the muscle that usually keeps acid out of the esophagus
. Treatment for GERD may include lifestyle changes, over-the-counter medications, prescription medications, and in some cases, surgery
