Calcium carbonate consumption during pregnancy: an unusual cause of neonatal hypocalcemia

J Child Neurol. 2002 Nov;17(11):853-5. doi: 10.1177/08830738020170111704.


The occurrence of hypocalcemia in a term infant after the first few days of life is known to result from excessive dietary phosphate, hypomagnesemia, neonatal hypoparathyroidism, hypovitaminosis D, and maternal hyperparathyroidism. Less well recognized is the possibility that maternal ingestion of antacids may cause late neonatal hypocalcemia. Our observations suggest that taking large doses of calcium carbonate during pregnancy may be a potential cause of neonatal hypocalcemia.
