Why would a male have low blood levels of calcium? | Masterjohn Q&A Files #16

Question: "Why would a male be low in calcium?" You either have something wrong with parathyroid hormone governing your calcium levels, in which case you would want to see a doctor about that, or you have a long-going deficiency of related nutrients. Not enough calcium and not enough vitamin D should not cause low serum calcium — unless the deficiency has been going on for a very long time and is very bad. Then again, I don't know what measurement you're referring to. So, maybe the calcium was a tiny bit low, and you remeasure it, and it's not low anymore; it was a fluke. But if you're talking about confirmed low serum calcium, then nutritionally, I would look at long-standing severe deficiencies of calcium and vitamin D. I'd follow it up with measurements of PTH and calcitriol to better assess the situation.
