I'm a 63yo female. is it true that calcium in my bloodstream means i'm losing bone calcium? bone density tests say i'm ok. are there other possibilies

Blood calcium: Blood calcium level is a balance between intake, excretion and deposition in bone. If your blood calcium is high it maybe due to increased intake, decreased excretion and removal from bone. This calcium balance is tightly regulated by parathyroid hormone and calcitonin. The cause can be determined by further testing.

Ca in blood - Normal: Everyone has calcium in their blood. Is it important for other things besides bone health, The normal range for calcium in blood is 8.5 to 10.2 mg/dL.(some variation exists in this range, depending on the lab testing it. Too much calcium or too little calcium in the blood can be a serious problem. Read about Calcium here:http://www.nlm.nih.gov/medlineplus/ency/article/003477.htm

Not sure exactly: What you mean. You need some calcium in your blood as it serves many purposes. If you are referring to elevated blood/serum calcium, it is possible that the reason a serum calcium is elevated is due to "stealing" calcium from the bones. But it can also be a sign of dehydration and kidney issues.

Not true: Everyone has calcium in their blood! There are normal ranges established for such chemicals in blood. If your calcium levels drops in blood then the body would replace it from the bones, where the calcium is stored. Keeping a normal level of calcium with additional supplementation as needed should be the goal. Be careful not to over do it as excess calcium, like other supplements, can be harmful.

Yes: while it is most likely that you will suffer from primary hyperparathyroidism which causes high calcium in the blood., You could also have a condition called familial Hypocalciuric hypercalcemia. You need to see an endocrinologist to figure out what condition you have and whether that condition needs to be treated or not. Thank you

Calcium in blood: There is a normal amount of calcium in the bloodstream, typically 8.5-10.4 mg/ 100ml of blood. If your blood calcium level is elevated it doesn't necessarily mean you are losing calcium, another cause should be sought. Excessive intake, parathyroid problems or other causes should be investigated. Thanks for trusting HealthTap!
