Excessive blood calcium is called hypercalcemia. To treat hypercalcemia, we must first identify the cause and treat the primary cause.
There are several causes of hypercalcemia in general:
1. Excessive calcium intake, which causes hypercalcemia, requires a reduction in calcium intake as well as vitamin D intake because vitamin D promotes calcium absorption and can generally be restored to normal levels with the discontinuation of calcium supplementation.
2. High blood calcium levels due to dehydration, such as severe diarrhea, vomiting, and profuse sweating, should be replenished by drinking more water, or by intravenous saline 0.9%, which, in addition to correcting dehydration, prevents the renal tubules from continuing to absorb calcium, and urinary calcium can be excreted.
3. If the blood calcium is too high due to primary hyperparathyroidism, it should be treated surgically.
4. For excessive blood calcium due to nodal disease, leukemia, lymphoma, or multiple myeloma, hormones may be used for treatment.
5. Severe hypercalcemia caused by malignant tumors is usually treated with phosphorus preparations, but the specific medication should be combined with the patient’s own situation.
