Well, I've had a medical test, and the results have astounded (and in a strange way, also pleased) me. When testing Vitamin D levels, a normal reading is between 30 and 80. Mine was 5. No, that's not a typo. I mean single-digit 5.
I'm astounded it was so low, because I'm quite certain I eat a diet high enough in Vitamin D that if the cloudy weather around here were to create a deficiency, it wouldn't be as low as all that. We eat a lot of salmon, tuna, and other seafood at our house, which are high on the list. Research tells me that certain conditions such as IBS, which I have, interfere with the absorption of Vitamin D, and that makes sense. Needless to say, I'm to be started on supplements as soon as possible.
Why does it please me? Because it explains so much. Vitamin D deficiency can create muscle aches, joint pain, weakness, fatigue, messed-up sleep patterns, and depression. How many of those things do I deal with? All of them. It's a relief to be able to point to a number and say, "Here is what's wrong. I'm not making excuses. I'm not lazy or unmotivated. I'm simply malnourished." I have renewed hope now, that maybe when we bring my levels up to healthy, I might be more energetic and less, well, just sleepy all the time.
From looking into what is rich in Vitamin D, it looks as if I may have to add some breakfast cereals back to my diet. I had been eliminating them to go low-carb. Looks like a session with my dietitian is in order too.
