Gastroesophageal reflux symptoms

Gastroesophageal reflux disease (GERD) is an esophagogastric motility disease. During the relaxation of the lower esophageal sphincter (LES), reflux of gastric contents into the esophagus is called gastroesophageal reflux (GER). There are two types of gastroesophageal reflux: physiological reflux and pathological reflux. Physiological reflux is caused by the spontaneous relaxation of LES, which is conducive to the discharge of gas from the stomach. Pushing peristalsis of the esophagus will push the gastric juice into the stomach. Normally, it will not cause esophageal membrane damage. Pathological reflux is a pathological phenomenon caused by gastroesophageal reflux insufficiency caused by many factors. Gastroesophageal reflux disease is a disease caused by reflux of the contents of the stomach or duodenum into the esophagus. Esophagitis is often associated, and about 10% -20% of the population have symptoms of gastric reflux, but X-ray endoscopy can be found without abnormalities and may not be recognized for a long time. Continuous development can lead to serious complications such as esophageal strictures, ulcers, bleeding, and Barrett's esophagus, which is a precancerous lesion. Extra-esophageal complications may also occur. Such as acidic laryngitis, respiratory spasm, lung injury complications.
