Diagnosis and management of gastrointestinal hemorrhage: What you need to know

ABSTRACT Acute gastrointestinal (GI) hemorrhage is a common cause for hospital admission that requires prompt diagnosis and multidisciplinary management to optimize clinical outcomes. Acute gastrointestinal bleeding (GIB) includes both upper and lower GI tract sources with an extensive list of differential pathologies. This review provides a systematic approach to both upper and lower GIB management, emphasizing initial resuscitation, stabilization, diagnostic evaluation to identify the source, and treatment modalities. Endoscopy remains the cornerstone for diagnostic and interventional purposes, significantly reducing the need for surgical procedures. However, lower GIB and severe or refractory cases may necessitate additional imaging and interventions, including surgical management. Integrating clinical guidelines, evidence-based strategies, and individualized care, this review delineates what you need to know to diagnose and manage acute GI hemorrhage.
