Hypocalcemia is a low level of calcium in your blood. It occurs when your body loses too much calcium or does not absorb enough from the foods you eat.


Call your local emergency number (911 in the US) or have someone call if:

  • You have a seizure.
  • You see or hear things that are not really there.

Return to the emergency department if:

  • You have a slow or uneven heartbeat and feel lightheaded.

Call your doctor or endocrinologist if:

  • You have dry skin and brittle nails.
  • Your symptoms do not go away, or they get worse.
  • You feel depressed, anxious, angry, or confused.
  • You have questions or concerns about your condition or care.


  • Medicines will be given to bring your calcium and vitamin D levels back to normal. You may also need medicines to prevent bone loss.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him of her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your doctor or endocrinologist every 3 to 6 months, or as directed:

You will need to return to have your calcium levels checked. Bring a list of any questions you have so you remember to ask them during your visits.

Eat foods rich in calcium:

Foods that contain calcium include milk, yogurt, cereals, and cheese. Leafy green vegetables, oranges, canned salmon, shrimp, and peanuts also contain calcium. Do not have caffeine or alcohol. These can slow your body's ability to absorb calcium. You may need to meet with a dietitian to help plan the best meals for you.

Get safe amounts of sunlight:

You may need to expose your skin to more sunlight if your body lacks vitamin D. Ask your healthcare provider how to safely expose yourself to UV light if you need it.

Do not smoke:

If you smoke, it is never too late to quit. Smoking increases the amount of calcium that leaves your body through your urine. Ask your healthcare provider for information if you need help quitting.
