Hypocalcemia is a condition in which there is too little calcium in the blood. A common form of hypocalcemia in babies is called neonatal hypocalcemia.
Some formulas have high levels of phosphate which can lower the blood calcium levels.
Hypocalcemia is thought to be caused by immaturity of parathyroid glands that make calcium. Hypocalcemia is more common in premature and low birthweight babies, because their parathyroid glands are less mature. It can also occur in babies who have a difficult birth and in babies of diabetic mothers. Symptoms of hypocalcemia may not be obvious in newborn babies.
