Reflux esophagitis is a common benign lesion of the digestive system, which usually does not affect the normal life span of patients after active treatment. Reflux esophagitis is an inflammatory disease caused by the backing up of gastric acid from the stomach and duodenum into the esophagus. Upper abdominal pain, nausea, acid reflux, chest tightness and heartburn are the main clinical manifestations, and esophageal hiatal hernia, obesity and Helicobacter pylori infection are all common causes of reflux esophagitis. In clinical practice, pharmacological and surgical treatments are commonly used to treat these conditions. Drug treatment can include H2 receptor antagonists, prokinetics, anticholinergics, such as ranitidine, etopride hydrochloride, atropine, etc. Surgical treatment mainly includes partial fundoplication, esophageal stent placement, hernia fissure repair, etc. During the treatment period, patients should try to maintain a light diet and choose more alkaline foods such as noodles and millet, so as to dilute the concentration of gastric acid and relieve the discomfort symptoms.
