A slow GI bleed typically presents with stools that are which color?

• A. Bright red
• B. Maroon
• C. Black
• D. Dark red

Answer: (D)

Stool color from a GI bleed reflects both where the bleed is and how fast blood travels through the gut. When bleeding is slow, blood spends more time in the intestines and mixes with the stool, becoming darker as it oxidizes and blends with stool matter. That slower transit typically yields a dark red appearance rather than the bright red seen with rapid bleeding or the black, tarry look of digested upper GI blood. So a slow GI bleed is most likely to present with dark red stools because the blood has had time to darken as it moves through the bowel.
