Etiology, detection, and management of fetal macrosomia in pregnancies complicated by diabetes mellitus.

Babies of mothers who have diabetes are more likely than babies of nondiabetic women to be large for gestational age. A greater proportion of their birth weight consists of fat mass, much of which is distributed to the trunk and abdomen. The maternal and fetal consequences of diabetic fetopathy, theories and evidence of how it develops, and management considerations relative to excessive growth of the fetus of a diabetic woman are explored in this chapter.
