Hello, I have been having severe hair loss for quite some time and had basically given up and accepted it’s just female pattern alopecia (even though it is not in my familial genes)....until recently. I was recently found to have a B12 level of 236. From what I have read even though that is considered within normal ranges, anything from 200-400 is low and can cause symptoms. I was placed on OTC supplements.
Now I am wondering if the hair loss could have been from the low b12 all along, or if there could be another deficiency, like iron deficiency, or thyroid issue after all, that was causing the hair loss to begin with. My MD says I am not anemic but some of my levels seem to be borderline and I was once found to be anemic in the past during a hospital stay. I would like another opinion. Below are my most recent labs:
Total iron 103, iron binding capacity 447 (normal high), methylmalonic acid 166, % Sat 23, Ferritin 109, RBC 4.84, H/H 13.7/42.3, MCHC 32.4 (borderline low and my 2 previous tests from 11/2017 and 7/2018 were low at 31.3 and 31.9), Serum Folate 5.8, B12 236, TSH 0.44 (borderline low).
Also note that my CRP was elevated at 9.7 which I read can increase ferritin levels, possibly masking a deficiency. My Sed Rate was normal at 9.
Any advice would be greatly appreciated.
