Hypocalcemia is when a person doesn't have enough calcium in the blood. In babies, it’s called neonatal hypocalcemia. Your baby can get it at different times and from different causes.
Doctors do not know what causes early hypocalcemia.
Late hypocalcemia is rare and has a number of known causes. Late hypocalcemia is usually caused by drinking cow's milk or formula that has too much phosphate. It may be connected to calcium and phosphorus levels in the body. It can also be caused by a problem with parathyroid hormone. This hormone is made by the parathyroid glands in the neck. It helps keep the amount of calcium and phosphorus at a normal level in the blood. Low parathyroid hormone levels can cause too little calcium in the blood. A number of conditions, such as DiGeorge syndrome (22q11.2 deletion syndrome), may cause low parathyroid hormone levels.
The symptoms of hypocalcemia in the newborn may look like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
