Attenuating type 2 diabetes with postpartum interventions following gestational diabetes mellitus

摘要

Women with a history of gestational diabetes should be screened during and after the postpartum period because of a high risk for developing type 2 diabetes mellitus.Although differences exist between guidelines practiced throughout various parts of the world,all recommend the use of cutoffs for fasting and/or postload plasma glucose to diagnose diabetes or prediabetes.The use of these glycemic parameters could be optimized when a trend is observed,rather than considering them as isolated values at various time points.As the presence of insulin resistance and betacell dysfunction start before glycemic changes areevident,the estimation of insulin sensitivity and beta-cell function by Homeostatic Model Assessment is suggested for women who have additional risk factors for diabetes,such as obesity.Disease-modifying lifestyle intervention should be the first-line strategy to prevent or delay the onset of diabetes in women with a history of gestational diabetes mellitus.Intensive lifestyle interventions are designed to decrease caloric intake and increase physical activity in order to reduce body weight and fat,which will in turn reduce insulin resistance.This article also reviews unique problems of postpartum women,which should be considered when designing and implementing an intervention.Innovative "out of the box" thinking is appreciated,as continued adherence to a program is a challenge to both the women and the health care personnel who deal with them.
