Phenotype of obesity and gastroesophageal reflux disease in the context of comorbidity in patients with cardiovascular diseases

Abstract

The relevance of studying such problems as gastroesophageal reflux disease (GERD) and obesity is caused by their high prevalence in the developed countries of the world. Epidemiological data indicate that obesity is a significant risk factor for developing GERD due to increased intra-abdominal pressure and gastroesophageal gradient, slowing of gastric evacuation and formation of hiatal hernia. Abdominal obesity increases the likelihood of complications of GERD: erosive esophagitis, Barrett's esophagus and adenocarcinoma. This fact is connected with humoral influences: increased production of pro-inflammatory cytokines and leptin, and decreased secretion of adiponectin. Treatment of comorbid patients requires higher dosages and longer courses of antisecretory medicines, and an additional prescription of ursodeoxycholic acid.
