[|Human|] Hi, I am a 56 yr old female, post menopausal. I recently fell and had a total hip replacement. I healed fine and post surgery, my surgeon wanted to run labs to see if I was calcium deficient. I have my primary care Dr, run labs when I was 7 weeks post surgery. My labs came back and the calcium was high at 10.6, the Vitamin D was very low at 18 and the PTH, intact w/out calcium was elevated to 77. I returned to my primary care Dr a little concerned perhaps a parathyroid tumor with all three of these results. She advise these levels were normal after having a hip replacement Can some please give me confirmation if that is correct.
[|AI|]  Hello, As such, there is no direct relationship between total hip replacement surgery and blood levels of Calcium and parathyroid hormone.  Parathyroid hormone is one of the factors controlling serum levels of calcium.  If the serum level of calcium is decreased Parathyroid hormone level increases to control it and calcium is released from bone into blood and vice versa.  If vitamin D level is low with increased serum calcium and parathyroid hormone.  It can be a normal finding due to vitamin D deficiency, but an expert opinion from endocrinology specialist should be done. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
