You did not answer my question. What about thiamine and b6 just to name a few. Those could be slightly low and doctors never check.
We go arround deficient all our lifes feeling crap. They should do some proper blood work.
How come it is this way in 2017?
Vitamin B6 deficiency and thiamine deficiency (beriberi) are not particularly common and are not particularly associated with Crohn's disease. They are most often seen in cases of severe starvation in famine-stricken areas. In contrast, folate deficiency and B12 deficiency
are of particular importance to Crohn's sufferers, for the reasons I outlined above, and thus are monitored more closely than most other vitamins.
Lab testing is not free. To routinely test for every vitamin that a CD patient might possibly be a little low in would be expensive, wasteful, and of only marginal benefit to most patients. It makes more sense to look where the problems are likely to occur.
