Learn About Infantile Low Calcium Level
Calcium is a mineral in the body. It is needed for strong bones and teeth. Calcium also helps the heart, nerves, muscles, and other body systems work well.
A low blood calcium level is called hypocalcemia. This article discusses hypocalcemia in infants. Hypocalcemia can occur at any age.
Hypocalcemia - infants
A healthy baby most often has very careful control of the blood calcium level by normal bodily systems.
Hypocalcemia is more likely to occur in newborns, more commonly in those who were born too early (preemies). Common causes of hypocalcemia in a newborn include:
- Certain medicines
- Diabetes in the birth mother
- Episodes of very low oxygen levels
- Infection
- Stress caused by serious illness
There are also some rare illnesses that can lead to low blood calcium level. These include:
- DiGeorge syndrome, a genetic disorder.
- The parathyroid glands help control calcium use and removal by the body. Rarely, a child is born with underactive parathyroid glands.
Babies with hypocalcemia often have no symptoms. Sometimes, babies with low blood calcium levels are jittery or have tremors or twitching. Rarely, they have seizures.
These babies may also have a slow heart rate and low blood pressure.
The baby may get extra calcium, if needed.
