Default Regarding thirst and BUN

I don't remember anyone mentioning diminished sense of thirst in connection with B12 deficiency. But, now that you mention it, I wonder whether there is sometimes a connection between lessened thirst in older people and the higher likelihood of B12 deficiency.

BUN. Looks like the attitude regarding BUN is a setup for missing cases of B12 deficiency. As you say, elevated BUN points to kidney problem, and usually low BUN (which can point to malnutrition) is not taken seriously.

Excellent observations.
