Last week I had an appointment with my new GP and she ordered a bunch of bloodwork so she could get baselines for a lot of different things. Having not seen a GP regularly since approximately 2007 I was pretty sure that the bloodwork would reveal that I was dying. Alas, I am not dying. As a matter of fact I appear to be pretty darn healthy. My Vitamin D is a little low so I need to start taking a supplement more regularly again, but this isn't hugely surprising since I live someplace where there isn't regular uninterrupted sunshine for 5-6 months a year and for a few of those months it's too darn cold to spend much time outside even when the sun is shining. Plus it's not nearly as low as it was a couple of years ago so that's good too.
Related, here is a bit of info on Vitamin D deficiency. It's extremely common in people that live in winter weather climates and I've heard it's near epidemic proportions for people who live in the US and Canada. It takes a simple blood test to find out if you are deficient and you can purchase the supplement relatively inexpensively and over the counter (at least here in the US).
I'm glad everything came back fine and that I'm not dying. I was sort of hoping that there would be some sort of medical explanation for my insomnia/exhaustion, but there does not appear to be. But that's ok, and I'll address it at a different appointment a little bit later.
