Untreated gestational diabetes mellitus carries significant risks of perinatal morbidity at all severity levels; treatment will enhance outcome.
A matched control of 555 gravidas, gestational diabetes mellitus diagnosed after 37 weeks, were compared with 1110 subjects treated for gestational diabetes mellitus and 1110 nondiabetic subjects matched from the same delivery year for obesity, parity, ethnicity, and gestational age at delivery. The nondiabetic subjects and those not treated for gestational diabetes mellitus were matched for prenatal visits.
A composite adverse outcome was 59% for untreated, 18% for treated, and 11% for nondiabetic subjects. A 2- to 4-fold increase in metabolic complications and macrosomia/large for gestational age was found in the untreated group with no difference between nondiabetic and treated subjects. Comparison of maternal size, parity, and disease severity revealed a 2- to 3-fold higher morbidity rate for the untreated groups, compared with the other groups.
Untreated gestational diabetes mellitus carries significant risks for perinatal morbidity in all disease severity levels. Timely and effective treatment may substantially improve outcome.

    • "Gestational diabetes mellitus (GDM) is defined by the American Diabetes Association (ADA) as " diabetes diagnosed in the second or third trimester of pregnancy that is not clearly overt diabetes " (American Diabetes Association, 2015, S13). It is associated both with adverse consequences for maternal and foetal health, including macrosomia, increased risk of caesarean section and increased neonatal unit admission (Catalano et al., 2012;Langer, Yogev, Most, & Xenakis, 2005;Schmidt et al., 2001), and an increased long-term risk for the development of pre-diabetes or type 2 diabetes mellitus (Catalano et al., 2012;Kim, Newton, & Knopp, 2002). GDM prevalence has recently been reported as 2–6% in Europe (Buckley et al., 2012), 9.3–25.5% internationally (Sacks et al., 2012) and 12.4% in Ireland (O'Sullivan et al., 2011). "

Moreover, a two-to fourfold increase in metabolic complications and macrosomia/large for gestational age was found in the untreated group with no difference between the nondiabetic and treated subjects [1]. Crowther et al. [2] randomly assigned 1000 women between 24 and 34 weeks of gestation who had GDM to receive dietary advice, blood glucose monitoring, and insulin therapy as needed (the intervention group) or routine care.

    ABSTRACT: Gestational diabetes mellitus (GDM) complicates 3-15% of pregnancies depending upon geographic location and ethnic groups, and its incidence is estimated to increase even further due to the increasing rates of obesity in the general population and the trend towards advanced maternal age in pregnancy. GDM is associated with adverse pregnancy outcome such as increased rate of fetal macrosomia, neonatal metabolic disturbances and maternal injuries. It was shown that there is an inverse relation between maternal glycemic control and the risk for complications. When diet and exercise therapy fail in achieving good glycemic control pharmacological intervention is warranted. This chapter will deal with the evidence regarding the various pharmacological intervention for glycemic control in women with GDM, when to start and what pharmacological agent to use.

    • "It increases the incidence of macrosomia and large for gestational age (LGA) babies which in turn increases the risk for shoulder dystocia, birth trauma and caesarean section [2]–[5]. Besides, the risks for perinatal mortality, neonatal hypoglycemia, hyperbilirubinemia, gestational hypertension and pre-eclampsia also increase in GDM patients [2], [4], [6]. Chances for development of type 2 diabetes mellitus are also reported to increase in both mother and infant later in their life [6]–[8]. "

    ABSTRACT: To assess the efficacy and safety of treating pregnant women with gestational diabetes mellitus in comparison to usual antenatal care. A systematic review and meta-analysis was conducted by including randomized controlled trials comparing any form of therapeutic intervention in comparison to usual antenatal care. A literature search was conducted using electronic databases together with a hand search of relevant journals and conference proceedings. Ten studies involving 3,881 patients contributed to meta-analysis. Our results indicated that gestational diabetes mellitus treatment significantly reduced the risk for macrosomia (RR, 0.47; 95% CI, 0.38-0.57), large for gestational age births (RR, 0.55; 95% CI, 0.45-0.67), shoulder dystocia (RR, 0.42; 95% CI, 0.23-0.77) and gestational hypertension (RR, 0.68; 95% CI, 0.53-0.87) without causing any significant increase in the risk for small for gestational age babies. However, no significant difference was observed between the two groups regarding perinatal/neonatal mortality, neonatal hypoglycemia, birth trauma, preterm births, pre-eclampsia, caesarean section and labor induction. Treating GDM reduces risk for many important adverse pregnancy outcomes and its association with any harm seems unlikely.
