Hypercalcemia is the medical word for “high blood calcium.” It is almost never normal and almost always requires further testing and often treatment of the underlying problem to bring the high blood calcium back into the normal range.

What causes hypercalcemia?

Hypercalcemia is usually a result of overactive parathyroid glands. These four tiny glands are situated in the neck, near the thyroid gland. Other causes of hypercalcemia include cancer, certain other medical disorders, some medications, and taking too much of calcium and vitamin D supplements.

Can hypercalcemia go away by itself?

People with mild hypercalcemia may not require treatment, and levels may return to normal over time. The doctor will monitor calcium levels and the health of the kidneys. If calcium levels continue to rise or do not improve on their own, further testing will likely be recommended.
