Q: what can cause vitamin b12 malabsorption? especially if you have low value, <109 pmol/l?

Intestine issue: B12 is absorbed in the far end of the small intestine. Conditions that involve that area can reduce absorption (infection/surgery/etc,). Dietary habits that reduce intake (vegan only) can lead to low levels.

Q: my vitamin b12 is 335 pg/ml then it says low: <146 pg/ml i rarely eat cause i dont have a appetite and at times go up to 4 or 5 days w/o food why?

Anorexia: Appetite is a complex process mediated by the brain, emotions, metabolic needs, health of the gut &amp; surrounding organs. Lack of weight loss would be good news here. I recommend a visit to your doctor to discuss the circumstances that preceded your anorexia &amp; that may contribute to its persistence. Simple testing is appropriate. Of note, your B12 level is normal.
