Low Calcium Level (Hypocalcemia) quiz

Take a quiz to find out what's causing your low Calcium Level (Hypocalcemia).

What is low calcium level (hypocalcemia)?

Hypocalcemia is a low level of calcium in your blood. Calcium is a mineral that helps the heart and other muscles function properly and it maintains strong teeth and bones. It also supports nerve function, so when your calcium levels are too low, nerve sensations are disrupted and your lips may feel numb and tingling.

Hypocalcemia can be caused by hypoparathyroidism. This occurs when your parathyroid glands (located in the neck behind the thyroid gland) don’t produce enough parathyroid hormone, which is important for regulating calcium levels. It can also be caused by vitamin D deficiency.


Symptoms of low calcium include numbness and tingling, painful menstrual periods, skin changes (dry and brittle hair, skin, and nails), and feeling depressed or anxious.


See your doctor if you suspect you have hypocalcemia or hypoparathyroidism. Treatment may include supplements (calcium, vitamin D, magnesium), diuretics, or injections of a medication that mimics your body’s natural parathyroid hormone.

Go to the ER if you have severe symptoms of low calcium levels, like extreme fatigue, confusion, seizures, loss of consciousness, or an abnormal heartbeat. Very low calcium levels can lead to death, so you need care immediately. Treatment may include oral or IV medications to increase calcium levels.
