Hiatal hernia is not a symptom of barrett’s esophagus, and there is no necessary relationship between the two, which needs to be established through gastroesophageal reflux disease. Hiatal hernia is a lesion that develops when tissue such as the cardia enters the mediastinum due to, for example, a weak diaphragm. Esophageal hiatal hernias are highly susceptible to gastroesophageal reflux, and GERD may be complicated by Barrett’s esophagus. Hiatal hernia is an important risk factor for the development of gastroesophageal reflux disease (GERD). Compared with GERD without hiatal hernia, those with hiatal hernia have more pronounced symptoms of reflux and acid exposure, and refluxed material such as gastric acid and food residue is more likely to erode the esophageal mucosa, which can increase the risk of serious complications such as Barrett’s esophagus. However, there is no direct pathogenic relationship between Barrett’s esophagus and hiatal hernia, and hiatal hernia is not a symptom of Barrett’s esophagus. It is advisable to seek medical attention for hiatal hernia or Barrett’s esophagus.
