In-Depth

What causes hyperparathyroidism?

Hyperparathyroidism may be caused by:

  • benign (non-cancerous) tumors on the parathyroid glands
  • enlargement of the parathyroid glands
  • vitamin D deficiency

Why is calcium so important?

Many people know that calcium is essential for bone and tooth strength and development, but it’s also important for:

  • nerve transmission
  • muscle contraction
  • helping blood clot

What are the symptoms of hyperparathyroidism?

Since high levels of calcium in the blood affect the nervous system, some symptoms of hyperparathyroidism are neurological in origin. While each child may experience symptoms differently, some of the most common include:

  • kidney pain (due to the presence of kidney stones)
  • bone pain (caused by diminished bone density)
  • aches and pains
  • abdominal pain
  • nausea
  • vomiting
  • fatigue
  • excessive urination
  • confusion
  • muscle weakness

The symptoms of hyperparathyroidism may resemble other conditions or medical problems, so always consult your child's physician for a diagnosis.

What are the risks of hyperparathyroidism?

If left untreated, hyperparathyroidism may lead to conditions including:

  • osteoporosis and osteomalacia (both bone-weakening diseases)
  • kidney stones (due to the increased level of calcium in the urine)
  • muscle weakness
