The influence of IGF-1 on fetal growth during pregnancy complicated by gestational diabetes mellitus

Abstract

Insulin-like growth factor-1 (IGF-1) is an important part of IGF system. The structure and function of IGF-1 are similar to that of insulin. Thus, IGF-1 may participate both in the gestational diabetes mellitus (GDM) pathogenesis and the development of some complications. IGF-1, as one of the most important growth factors “in utero”, may influence the intrauterine growth leading to fetal macrosomia. The aim of the study was to present the structure and function of IGF-1 in terms of carbohydrate metabolism disturbances and to determine the role of IGF-1 on fetal growth during pregnancy complicated by GDM. Fetal growth is an extremely complex process and depends on many factors, including IGF-1 concentration.
