High Levels of Vitamin B12 and Ferritin: Any pointers?
Blood Cancers & Disorders | Last Active: Jan 23 7:55am | Replies (112)Comment receiving replies
I have recently had two B12 labs, both in 2000+. It was part of a series of tests ordered because I had just been diagnosed{Dec.19th ] with Small Fiber/autonomic peripheral neuropathy in a non-length dependent pattern. My neurologist had anticipated I would have a B12 deficiency???...All of my extensive testing looking for the cause of the neuropathy were negative except for the B12.... I am being referred to an oncologist and we are NOW looking for a cause of the high B12 as well as the cause of neuropathy? I am very interested in reading your comments because there is very little info available, also I am so happy to have found this group.

Welcome to Connect, @marlenerose33.
Along with some more information on the significance of b12 levels, https://medlineplus.gov/ency/article/003705.htm I found this recent study that I thought might interest you:
"An observational study of vitamin b12 levels and peripheral neuropathy profile in patients of diabetes mellitus on metformin therapy” https://www.sciencedirect.com/science/article/abs/pii/S1871402117302874
With regard to neuropathy, very often there is no identifiable cause – there are a number of conditions that can trigger it. May I ask if you noticed anything that might have triggered the neuropathy?
