Modern understanding of the etiopathogenesis of gastroesophageal reflux disease: clarification of key aspects and perspectives

Abstract

Gastroesophageal reflux disease (GERD) is one of the most common diseases among gastroenterological pathologies. The relevance of GERD is due not only to medical aspects, but also to economic ones, since the vast majority of patients are young working-age people. The prevalence of GERD ranges from 20% to 30% of the adult population. GERD is associated with a significant decrease in quality of life and the development of Baretta’s esophagus and esophageal adenocarcinoma. GERD is a chronic disease with spontaneous repetitive spillage of gastric or duodenal-gastric contents into the esophagus, with typical complaints of heartburn and regurgitation. The pathogenesis is complex and includes the following aspects: decreased tone of the lower esophageal sphincter, diaphragmatic hernia, impaired protective function of the esophageal mucosa and esophageal motility, and increased intra-abdominal pressure. Obesity plays a significant pathogenetic role in the development of GERD. Weight loss is associated with symptom relief and a reduced risk of complications. Diagnosis of GERD is based primarily on typical clinical symptoms and empirical trial therapy with PPI. Treatment includes lifestyle changes, medications, and surgery. Еndoscopy and pH monitoring additionally contribute to the correct diagnosis. Further research on pathogenetic mechanisms is needed to implement effective strategies for diagnosis, treatment and prevention of complications.
