Pediatric Hypercalcemia

Hypercalcemia occurs when calcium levels in a child’s blood are too high.

What is Pediatric Hypercalcemia?

Hypercalcemia is a condition caused by having too much calcium in the blood. Normally, your child’s parathyroid gland produces a hormone that helps regulate the amount of calcium in the blood. Vitamin D, which your child gets from eating certain foods and from sunlight, also helps with this process.

When the parathyroid does not release the correct amount of hormone, or if your child suffers from a vitamin D deficiency, they may end up with too much calcium in the blood.

Abdominal pain
Constipation
Curved spine
Fractures
Frequent urination
Headache
Irritability
Muscle twitches
Muscle weakness
Nausea or vomiting
Pain near the kidneys
