Quizplus · Accepted Answer

GERD stands for gastroesophageal reflux disease, which occurs when the lower esophageal sphincter (LES) weakens or relaxes abnormally, allowing the stomach's acidic contents to flow back up into the esophagus. The repeated exposure of the unprotected lining of the esophagus to gastric juice (which contains acid and pepsin) can cause inflammation, irritation, and damage to the esophageal tissues, leading to symptoms such as heartburn, regurgitation, chest pain, hoarseness, and difficulty swallowing.
