Which factor after GI surgery may impact the absorptive function of the bowel?

• A. Bowel length
• B. Specific segment of small bowel that has been resected
• C. Residual disease in the remaining intestine
• D. Absence of colon and/or ileocecal valve

Answer: (A)

The amount of small intestine that remains is the main driver of how well absorption can occur after surgery. Absorptive surface area scales with length, so shorter bowel means less surface for nutrients to be taken up, leading to reduced overall absorptive capacity. While which segment was removed, residual disease, or absence of the colon/ileocecal valve can influence specific nutrients or aspects of absorption, the total remaining length sets the baseline for how much absorption is possible. The body can adapt to some degree over time, but the foundational limit is the amount of bowel left.
