Bile reflux gastritis (BRG) is a gastro-intestinal condition especially characterized by the reflux of bile into the stomach, further leading to mucosal inflammation along with various other clinical manifestations. Despite its increasing recognition, BRG remains understudied, with limited understanding of its epidemiology, pathophysiology, and optimal therapeutic strategies. Present narrative review aimed to comprehensively examine the available literature on BRG, focusing on its prevalence, risk factors, pathophysiology, clinical presentation, diagnostic modalities, and available therapeutic strategies. A comprehensive literature search was conducted using PubMed, Embase, Google Scholar and Cochrane databases. Relevant studies were included based on predefined inclusion and exclusion criteria. A narrative synthesis was conducted to summarize and interpret the findings. The prevalence of BRG remains uncertain due to diagnostic challenges. Risk factors include impaired gastrointestinal motility, sphincteric dysfunction (pyloric sphincter and the lower oesophageal sphincter), biliary tract disease, and certain medications. The pathophysiology involves bile acid-induced mucosal injury, inflammation, and impaired gastric defence mechanisms. Clinical manifestations are often nonspecific. Diagnostic modalities primarily include endoscopy and bile acid reflux testing. Management strategies encompass lifestyle modifications, medical therapy, and in severe cases, surgery. BRG is a complex condition with significant clinical implications. Further research is needed to refine diagnostic criteria, elucidate pathophysiological mechanisms, and develop effective therapeutic interventions. Addressing knowledge gaps in epidemiology, risk factors, and long-term outcomes is crucial for improving patient care.
