Question: B12 and cold sweats

 nuttybar - Sat Apr 19, 2008 7:44 pm

Can B12 deficiency cause cold sweats? Perhaps it is a problem controlling temperature? I have borderline low B12, a lot of symptoms, mostly peripheral neuropathy kinds of things, but aside from pain, the thing that bothers me the most is breaking out into profuse sweats even though I'm cold. So, could B12 deficiency be causing this? The sweats are extreme enough to make me feel really dehydrated pretty quickly and my clothes end up drenched. It's hard to get the sweating to stop once it starts. I usually just take a nap so that I will be asleep and will not notice how cold I am so that I will stop bundling up from the cold. When I wake up, the sweats will be somewhat better. I often have a low grade fever (between 100 and 101), but I don't think that I have any more or less of one than I usually do when the sweating starts. I also usually have a slightly elevated WBC (just barely out of normal range) and slightly above normal (just barely out of normal range) MHC and MCHC.

User avatar Hello -

While I am unaware of the sort of sweats you describe being related directly to B-12 deficiency, neuropathy can extend to the autonomic nervous system, and so to loss of normal autonomic function such as sweating. However, with the fever (which if above 100 isn't low grade, but a frank fever) and the (slightly) elevated white count, I am wondering if you've had a mono spot test done. Mononucleosis can cause these sorts of symptoms also, as can several other systemic diseases. I'd definitely have everything ruled out before blaming this on the B-12 deficiency.

Please do follow up with us here. Hope this is helpful. Good luck to you.
