[Hypoparathyroidism and pregnancy].

Any unrecognized or ill-controlled hypoparathyroidism, during pregnancy, may result in often severe fetal and neo-natal complications. Maintaining an accurate calcium-phosphorus balance is absolutely necessary to a good pregnancy in a woman with hypoparathyroidism. Alterations of the calcium-phosphorus metabolism, during pregnancy, make it more difficult to treat hypoparathyroidism. The treatment is based, essentially, on an appropriate vitamin D intake, with regular monitoring of the calcemia.
