My Calcium level was 12.5 and was an indicator of hypercalcemia which can be caused by a number of other things. My hypercalcemia was caused by hyperparathyroidism due to a benign growth on my lower right parathyroid. In my situation, the elevated calcium contributed cognitive problems due to excessive calcium in my brain over a prolonged period of time. I assume that your doctor wants to monitor it for now. If you end up with a situation like mine….make sure that they check that calcium levels have dropped before stitching you up. A friend had the same procedure at a different state and hospital, but the surgeon did not check that the levels during the operations and she had to have procedure again. Also my PtH level was 136 pg/mL and I am 57y/o F.
