Hypocalcemia (Child)
Hypocalcemia is when there is not enough calcium in the body. Calcium is a mineral. It helps the heart and other muscles work well. It’s also needed to grow and maintain strong bones and teeth. Hypocalcemia may be caused by:
Hypocalcemia can cause the muscles of the face, hands, and feet to twitch without your child’s control (spasm). It can also cause numbness or tingling around the mouth, or in the hands and feet. Other problems may include depression and memory loss.
A blood sample will be taken to check your child’s calcium level. The test also helps figure out if hypocalcemia may be caused by a problem with your child’s kidneys, or with the gland that controls the calcium level (parathyroid gland). Depending on the cause, your child may be given an oral calcium supplement. In severe cases, a child may need IV (intravenous) calcium gluconate. Your child may also have a vitamin D shot or supplement. If your child’s problem is caused by low magnesium, treatment will be given to raise it to a healthy level.
Home care
Your child’s doctor may prescribe calcium and vitamin D supplements. They may prescribe other medicines or minerals. Follow all instructions for giving these.
General care
-
Give your child any medicines or supplements as directed.
-
Help your child make diet changes as instructed. You may be told to give your child more calcium-rich foods. These include dairy products like milk, cheese, and yogurt. Some nondairy foods that contain calcium include fortified soy milk and orange juice, fortified cereals, chia seeds, and dark green leafy vegetables, such as kale, collard greens, broccoli, or spinach.
-
Limit soft drinks and soda. Many of these drinks have phosphates. These can make it harder for your child’s body to absorb calcium.
-
Try to have your child play outside for at least 20 minutes each day. Sun on the skin helps the body make vitamin D. This helps your child absorb calcium.
Follow-up care
Follow up with your child’s doctor, or as advised.
