Hypocalcemia means that the amount of calcium in your blood is lower than normal. Calcium is a mineral that is very important for:
Severe hypocalcemia can be life threatening.
What is the cause?
Possible causes of hypocalcemia include:
You are not getting enough calcium or vitamin D from your diet. Vitamin D helps your body take calcium from the food you eat and use it to build bone.
Your intestines are not absorbing calcium.
You have an imbalance of minerals or a low albumin (protein) in your blood. Some of the conditions that cause an imbalance of minerals include:
Kidney disease. Your kidneys are located on each side of your spine above your waist. They make urine by filtering and removing waste products and water from your blood
An inflamed pancreas. The pancreas is an organ in your upper belly behind your stomach that controls insulin levels
Parathyroid gland problems. The parathyroid glands are in your neck and they control the levels of calcium and phosphorus in the blood.
You are taking a medicine that affects the level of calcium in your blood.
What are the symptoms?
Symptoms may include:
Numbness or tingling around your mouth or in your feet and hands
Muscle spasms in your face, feet, and hands
Hallucinations (seeing or hearing things that are not there)
How is it diagnosed?
Your healthcare provider will ask about your symptoms and medical history and examine you. Tests may include:
Blood and urine tests
An ultrasound, which uses sound waves to show pictures of organs inside your belly
You may have tests or scans to check for other possible causes of your symptoms, such as: scans of your parathyroid gland or blood tests to check how well your kidneys are working.
How is it treated?
Your treatment will depend on the cause. If you are not getting enough calcium or vitamin D from your diet, eating foods rich in calcium or taking a vitamin D supplement may be all you need to do.
If you take medicine that makes you lose calcium, your provider may prescribe a different kind of medicine. Your provider may suggest that you eat more foods rich in calcium or take a calcium supplement.
If your hypocalcemia is severe, you will probably stay in the hospital and be given calcium by IV.
If low calcium is caused by a medical problem, treating the medical problem may improve your calcium level.
You may have blood tests on a regular basis to check your calcium level.
How can I take care of myself?
Many fruits and vegetables, as well as dairy products, are good sources of calcium. Some examples of foods rich in calcium are:
Yogurt, 2% milk, low-fat cheese, soy milk, and rice milk
Beans and lentils
Calcium-fortified orange juice or cereal
Vegetables such as broccoli, kale, spinach, and turnip greens
Follow the full course of treatment prescribed by your healthcare provider. Ask your provider:
How and when you will hear your test results
How long it will take to recover
If there are activities you should avoid and when you can return to your normal activities
How to take care of yourself at home
What symptoms or problems you should watch for and what to do if you have them
Make sure you know when you should come back for a checkup.
How can I help prevent hypocalcemia?
Make sure that you get enough calcium and vitamin D each day, either in foods or as supplements.
