A client presents with high serum homocysteine, fatigue, & stomach pains associated with high-protein meals such as medium-rare steak. Which of the following is most likely?

Correct Answer:

low HCL & low B12 status

Fatigue and stomach pains with high-protein meals are non-specific symptoms that could be associated with low HCL (hydrochloric acid), low B12, or low iron status. However, high serum homocysteine is more specifically associated with low B6, B12, or folate status. Low HCL can cause or exacerbate low B12 status since optimal levels of HCL in the stomach are needed to produce intrinsic factor, which is required for B12 absorption.
