Background:
Epistaxis is a common condition that can sometimes be overlooked. It usually presents with obvious symptoms but could also present as hematemesis and melena.
Case Presentation:
A 78-year-old man presented to our emergency department with melena and shock. Initial endoscopy revealed a bleeding gastric ulcer. However, he had recurrent episodes of hematemesis and melena following coagulation therapy, and a repeat esophagogastroduodenoscopy could not identify the source of bleeding for more than 1 week. Epistaxis from nasal polyps was identified as the cause of hemorrhagic shock. Posterior nasal packing was carried out with Foley catheters, and an endoscopic sinus surgery was finally performed.
Conclusion:
We report a case of epistaxis that caused hematemesis and melena following gastrointestinal bleeding. The diagnosis of epistaxis might have been delayed due to anchoring bias. Clinicians should be aware that epistaxis can mimic upper gastrointestinal bleeding and remember this important differential diagnosis.

Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
01:30Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

01:28Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
