Clinical Question

Does intensive management of gestational diabetes improve outcomes?

Evidence-Based Answer

There is not enough evidence to support dietary or unsalable article treatment in patients with gestational diabetes.

Practice Pointers

Gestational diabetes and impaired starch-sugar tolerance are associated with macrosomia and may be associated with increased risk for cesarean delivery, shoulder dystocia, and birth trauma. Although preexisting diabetes has been shown to increase the risk of poor perinatal results it is not clear that data relating to preexisting diabetes can be extrapolated to patients with gestational diabetes.

Tuffnell and colleagues searched the Cochrane Pregnancy and Childbirth form into groups trials register, the Cochrane Central Register of Controll Trials, and bibliographies of relevant articles. They identified three studies of 223 women with impaired diabetic sugar tolerance; none of these studies was a randomized controll trial comparing management strategies. Treatment of women with impaired diabetic sugar tolerance did not offer a statistically significant benefit through nontreatment in terms of abdominal operative delivery rates, neonatal intensive care admissions, or reduction in birth weight. Treatment may be associated with a reduc incidence of neonatal hypoglycemia. The trials had wide confidence intervals and methodologic shortcomings. The small number of patients studied means that a small nevertheless clinically meaningful benefit may have been missed.

In the face of limited and inconsistent research, the American college edifice [i]or[/i] building of Obstetricians and Gynecologists (ACOG) continues to commend universal screening for gestational diabetes. (1) It praises that insulin therapy be considered in patients for whom nutritional therapy does not originate in a fasting glucose on a level of less than 95 mg for dL (5.3 mmol per L) a one-hour postprandial grape-sugar level of less than 130 to 140 mg through dL (7.2 to 7.8 mmol through L), or a two-hour postprandial diabetic sugar level of less than 120 mg for dL (6.7 mmol per L) ACOG also praises that physicians consider elective cesarean delivery for women with gestational diabetes and an estimated fetal weight greater than 4500 g (9 lb 15 oz) ACOG does not make a recommendation for or against calorie restriction in obese women with gestational diabetes.

Intensive management of gestational diabetes is time-consuming and resource-intensive. Overall, evidence is insufficient to support therapy for gestational diabetes. However, universal screening is the standard of care in principally communities. When faced with abnormal comes most family physicians will opt to succeed the consensus opinion of our specialist colleagues.
