Moreover, the disturbances of Ca2+ may be mirrored by Mg2+, or conversely, as in hypocalcemia and hypomagnesemia. Infants of diabetic mothers (IDMs) and infants with fetal growth restriction (FGR) may present with low serum levels of either Ca2+ or Mg2+ or both. Serum values for Ca2+ and Mg2+ above or below accepted normal values are of concern in any infant and warrant further clinical studies. Magnesium disorders are discussed in Chapter 105.
