What is Calcium (Calcium)?
Calcium is measured as part of a electrolytes panel. Your calcium is normal — important for bones, muscles, and nerves.
What does a high Calcium mean?
Your calcium is elevated (hypercalcemia). Symptoms include fatigue, nausea, frequent urination, and confusion. Most commonly caused by hyperparathyroidism or vitamin D toxicity.
If markedly elevated: Critically high calcium is a medical emergency.
What does a low Calcium mean?
Your calcium is low (hypocalcemia). Can cause muscle cramps, numbness/tingling, and fatigue. Often linked to vitamin D deficiency or thyroid/parathyroid issues.
If markedly low: Critically low calcium can cause muscle spasms, seizures, and heart problems. Seek immediate medical care.
