Sample item

A patient several years after Roux-en-Y gastric bypass has fatigue, glossitis, neuropathy, and macrocytosis. Which deficiency should be suspected?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Vitamin B12 deficiency

Gastric bypass can impair vitamin B12 absorption through reduced intrinsic-factor exposure and altered anatomy. Lifelong nutritional surveillance and supplementation are important after bariatric procedures.

Option by option

  • A. Vitamin C excess

    Vitamin C excess does not cause macrocytic neuropathy.

  • B. Vitamin B12 deficiency (correct)

    Correct. Macrocytosis and neuropathy point to B12 deficiency.

  • C. Sodium excess

    Sodium excess is unrelated to this pattern.

  • D. Vitamin K toxicity

    Vitamin K toxicity is not the expected post-bypass problem.
