Oh, I am so pissed off, I really am. Spoke to my doctor this evening, and it turns out that my vitamin D level is WAY WAY low. Ridiculously low. The bottom of the reference range for "normal" is 75 nmol/L, and mine is 14!
When I phoned up the surgery three weeks ago to ask about the results of my blood test, this was the sort of information they were supposed to give me. I had specifically asked to have my vitamin D level tested since I know it's one of the things that can cause unremitting fatigue, especially mental fatigue. And the fun thing? I take a multivitamin that supplies 100% of the RDA of vitamin D, and have it supplemented in my soy milk, and I drink a LOT of soy milk.
So I started looking this up, and found "Occasionally, drugs used to treat fits, particularly phenytoin (epanutin), can interfere with the liver's production of 25 hydroxy-vitamin D." I'm on an antiepileptic for bipolar. Checked that and found low vitamin D level is a known side-effect with carbamazepine - there are studies in actual journals on PubMed. GODS DAMN IT! What are the other symptoms that go along with low vitamin D level? Aches, pains and LEG CRAMPS!!! My legs are so stiff and sore that I can hardly walk. And according to some of the research I've seen and web sites I've read, the deficiency is so severe that over-the-counter supplements and/or more time in the sun isn't enough to help.
Well, that would be an explanation of why I'm so damned ill right now, wouldn't it? Covers all the symptoms. Hopefully, it means that I should be able to recover again fairly quickly.
But honestly, why didn't whichever doctor who looked at the results before flag up that vitamin D level as insanely low? Or why didn't the nurse I spoke to tell me about it? That's three whole weeks of treatment missed :/

Date: 2011-03-18 08:19 am (UTC)Good plan re mega supplement. Are you more at risk of lower levels cos of being half-Burmese? I know doctors are supposed to lookout for it in 'non whites' for that reason.
IIRC yo can get VitD via jab too, but dunno if that's problematic for you. Either way hope treatment works ASAP.

Date: 2011-03-18 01:13 am (UTC)Even with getting more sun over the summer, my levels didn't change, either - my best guess is that I'm simply not storing it well.
I'm guessing you'll get something like what I do, which is a massive dose once or twice a week (I do 50,000 IU twice a week: most OTC pills are 1000 or 2000 IU, to compare, here.)
Very few side effects, but there's one I wanted to note: when I started taking it (though not any more), the day after I took it, I'd have a weird low-grade apathy. Not quite so much tired-exhausted as lethargic. (But the other days were much better than previously, so overall, it's a win.)
I found that taking it earlier in the day (afternoon, rather than bedtime) seems to help - and also just that the side effect went away. But when you're starting, you may want to time it for days where your next day doesn't have as many demands, if that's practical, just to see.

Date: 2011-03-19 04:16 am (UTC)Wikipedia tells me (since I really need to aim at bed, and want to answer this now) that one IU of "is the biological equivalent of 0.025 μg cholecalciferol/ergocalciferol"
Here, the over the counter supplements you can get are usually 1000 or 2000 IU (sometimes you'll see 3000), and the recommended daily dose is around 4000 IU (including intake from food: it's regularly added as a supplement in milk and some other products.)
Wikipedia also tells me that the EU is more likely to label it in μg (micrograms), with a daily suggested intake of 5 micrograms a day (which comes out to about 200 IU) while Australia and New Zealand recommend somewhere between 5 and 15 micrograms based on age.
As
Part of that is that there are two different variants of Vitamin D - D2 and D3. Most over the counter supplements are D3, but the megadoses are mostly D2. (I understand it has to do with how much you can compress into a pill shape and the chemistry, but I don't know about the details.) and there's some thoughts (but not a lot of science) that D2 is much less efficient as a supplement than D3 (so you need more of it to start with.)
Anyway, it's working for me: I feel a lot better, and my levels went from 18 when I was first tested to the upper 47 when I was tested in January.
It's done by a simple blood test. Levels do vary summer to winter for a lot of people (since if you're out in the sun at all in the summer, your body might be making some), so it's good to get it retested periodically. Symptoms of deficiency include exhaustion, lots of low-grade aches and pains that aren't really in the joints, aren't really in muscles, just hurt, and some cognitive function issues in some people.
It is possible to hit toxicity levels if you take too much, which is another reason for semi-regular testing. (Mine are every six months right now, for both thyroid and Vitamin D, unless I start feeling symptoms.)
There's a lot of mixed research out there: what I can say is that my endocrinologist found a lot of people who felt better with higher levels, and that I certainly am one of them. I do want to track down the cause of why the levels are low, but need to solve job hunting before I do that (since it'll probably take a while, and I may end up moving and therefore changing doctors - plus, this being the US, health coverage costs me money to use.)

Date: 2011-03-19 09:16 pm (UTC)b) Mine checked vitamin B12, folate and vitamin D, but I don't know what else can be checked. You'd be best asking any doctor friends you happen to have :)
