What color is the blood vomited in gastric bleeding?

Gastrointestinal bleeding may manifest as vomiting of coffee-ground-like gastric contents. In cases of acute or massive bleeding, patients may also vomit bright red blood. Prompt hospital admission is essential to restore intravascular volume, maintain fluid and electrolyte balance, prevent shock, and perform endoscopic hemostasis. It is necessary to determine the underlying cause of bleeding based on clinical experience and diagnostic test results, and to treat the specific etiology definitively.
