Bleeding in the upper part of the digestive tract, including esophagus, stomach, and duodenum.

• A. Lower GI Bleed
• B. Upper GI Bleed
• C. Esophagitis
• D. Mallory-Weiss

Answer: (B)

Bleeding from the esophagus, stomach, or duodenum is best described as an upper GI bleed. The key idea is anatomical: the upper part of the digestive tract includes those organs, and the division between upper and lower GI is the ligament of Treitz. So any bleed originating above that point is categorized as an upper GI bleed, no matter which of those upper organs is the source. This category covers a range of causes, from esophageal varices and peptic ulcers to esophagitis or a Mallory-Weiss tear. In contrast, a lower GI bleed comes from parts of the tract below that ligament, such as the small intestine further along, the colon, or the rectum. Clinically, upper GI bleeds often present with hematemesis (vomiting blood) or melena, while lower GI bleeds more commonly present with hematochezia.
