[The influence of metabolic changes on intrauterine fetal growth in normal gestation and gestation complicated by diabetes].

Based on published clinical studies, this paper reviews the influence of metabolic changes during pregnancy on intrauterine fetal growth. Data are collected concerning the metabolic aspects of both normal pregnancies and those complicated by diabetes as well as hormonal changes having significant impact on metabolism during pregnancy. The issues of gestational insulin resistance and the metabolism of carbohydrates, lipids, proteins, and amino acids are discussed. Factors influencing birth weight and intrauterine fetal growth, including metabolic and hormonal mechanisms and the function of the placental barrier, are also considered.
