> Hmm, my doc did a calcium check as well. Despite my vitamin D deficiency the calcium value was normal. I read that in vitamin D deficiency the PTH value can be increased. If I suddenly start supplementing vitamin D3 the calcium level might increase too much and, therefore, cause symptoms of hypercalcemia. Could this be the case???
I would request a PTH lab. Low Vit. D and/or low calcium shows up sooner as elevated PTH before your blood calcium shows deficiency, by a long shot (I have read multiple times, but I'm no expert). I don't imagine you would get to excess blood calcium with Vit. D and calcium supplementation (but I'm still a novice at this).
