ada gestational diabetes guidelines 2021

Similar to the targets recommended by ACOG (upper limits are the same as for GDM, described below) (35), the ADA-recommended targets for women with type 1 or type 2 diabetes are as follows: Fasting glucose 7095 mg/dL (3.95.3 mmol/L) and either, One-hour postprandial glucose 110140 mg/dL (6.17.8 mmol/L) or, Two-hour postprandial glucose 100120 mg/dL (5.66.7 mmol/L). The U.S. Preventive Services Task Force recommends the use of low-dose aspirin (81 mg/day) as a preventive medication at 12 weeks of gestation in women who are at high risk for preeclampsia (108). Pregnancy is a ketogenic state, and women with type 1 diabetes, and to a lesser extent those with type 2 diabetes, are at risk for diabetic ketoacidosis (DKA) at lower blood glucose levels than in the nonpregnant state. Available from, Aspirin for the prevention of preterm and term preeclampsia: systematic review and metaanalysis, Aspirin versus placebo in pregnancies at high risk for preterm preeclampsia, Low-dose aspirin for the prevention of preterm delivery in nulliparous women with a singleton pregnancy (ASPIRIN): a randomised, double-blind, placebo-controlled trial, A Cost-benefit analysis of low-dose aspirin prophylaxis for the prevention of preeclampsia in the United States, Aspirin for the prevention of preeclampsia and potential consequences for fetal brain development, International Society for the Study of Hypertension in Pregnancy (ISSHP), Hypertensive disorders of pregnancy: ISSHP classification, diagnosis, and management recommendations for international practice, ACOG Practice Bulletin No. Complications in your baby can be caused by gestational diabetes, including: Insulin is the first-line agent recommended for treatment of GDM in the U.S. Some women develop diabetes for the first time during pregnancy. The American Diabetes Association (ADA) "Standards of Medical Care in Diabetes" includes the ADA's current clinical practice recommendations and is intended to provide the components of diabetes care, general treatment goals and guidelines, and tools to evaluate quality of care. The insulin requirement levels off toward the end of the third trimester with placental aging. B. 3. . A follow-up study at 510 years showed that the offspring had higher BMI, weight-to-height ratios, waist circumferences, and a borderline increase in fat mass (82,83). More recently, glyburide failed to be found noninferior to insulin based on a composite outcome of neonatal hypoglycemia, macrosomia, and hyperbilirubinemia (66). B, 14.5 In addition to focused attention on achieving glycemic targets A, standard preconception care should be augmented with extra focus on nutrition, diabetes education, and screening for diabetes comorbidities and complications. While individual RCTs support limited efficacy of metformin (60,61) and glyburide (62) in reducing glucose levels for the treatment of GDM, these agents are not recommended as first-line treatment for GDM because they are known to cross the placenta and data on long-term safety for offspring is of some concern (34). The preconception care of women with diabetes should include the standard screenings and care recommended for all women planning pregnancy (16). Mothers who substitute fat for carbohydrate may unintentionally enhance lipolysis, promote elevated free fatty acids, and worsen maternal insulin resistance (63,64). Glyburide was associated with a higher rate of neonatal hypoglycemia, macrosomia, and increased neonatal abdominal circumference than insulin or metformin in meta-analyses and systematic reviews (72,73). Ideally, the A1C target in pregnancy is <6% (42 mmol/mol) if this can be achieved without significant hypoglycemia, but the target may be relaxed to <7% (53 mmol/mol) if necessary to prevent hypoglycemia. The international consensus on time in range (50) endorses pregnancy target ranges and goals for TIR for patients with type 1 diabetes using CGM as reported on the ambulatory glucose profile; however, it does not specify the type or accuracy of the device or need for alarms and alerts. Use of the CGM-reported mean glucose is superior to the use of estimated A1C, glucose management indicator, and other calculations to estimate A1C given the changes to A1C that occur in pregnancy (49). E A dosage of 162 mg/day may be acceptable; currently in the U.S., low-dose aspirin is available in 81-mg tablets. 2451 Crystal Drive, Suite 900 Arlington, VA 22202. Women with GDM have a 10-fold increased risk of developing type 2 diabetes compared with women without GDM (107). Family planning should be discussed, including the benefits of long-acting, reversible contraception, and effective contraception should be prescribed and used until a woman is prepared and ready to become pregnant (1115). Women with GDM have a 10-fold increased risk of developing type 2 diabetes compared with women without GDM (119). Readers who wish to comment on the Standards of Care are invited to do so at professional.diabetes.org/SOC. Diabetes confers significantly greater maternal and fetal risk largely related to the degree of hyperglycemia but also related to chronic complications and comorbidities of diabetes. ADA - E Consensus. All women of childbearing age with diabetes should be informed about the importance of achieving and maintaining as near euglycemia as safely possible prior to conception and throughout pregnancy. CONCEPTT (Continuous Glucose Monitoring in Pregnant Women With Type 1 Diabetes Trial) was a randomized controlled trial of continuous glucose monitoring (CGM) in addition to standard care, including optimization of pre- and postprandial glucose targets versus standard care for pregnant women with type 1 diabetes. A meta-analysis of 11 RCTs demonstrated that metformin treatment in pregnancy does not reduce the risk of GDM in high-risk women with obesity, polycystic ovary syndrome, or preexisting insulin resistance (56). Partner with Us. Time above range (>140 mg/dL [7.8 mmol/L]), goal <25%. 14.7 Fasting and postprandial self-monitoring of blood glucose are recommended in both gestational diabetes mellitus and preexisting diabetes in pregnancy to achieve optimal glucose levels. These recommendations were developed by a panel of experts who built upon prior Standards be reviewing the latest and most significant scientific research. Of women with a history of GDM and prediabetes, only 56 women need to be treated with either intervention to prevent one case of diabetes over 3 years (123). Target range 63140 mg/dL (3.57.8 mmol/L): TIR, goal >70%, Time below range (<63 mg/dL [3.5 mmol/L]), goal <4%, Time below range (<54 mg/dL [3.0 mmol/L]), goal <1%. . ACOG and ADA recommend the following target levels to reduce risk of macrosomia Fasting or preprandial blood glucose values < 95 mg/dL Postprandial blood glucose values < 140 mg/dL at 1 hour and < 120 mg/dL at 2 hours Review weekly but may alter based on degree of glucose control Diet and Exercise Nutritional assessment and plan 15.22 Insulin resistance decreases dramatically immediately postpartum, and insulin requirements need to be evaluated and adjusted as they are often roughly half the prepregnancy requirements for the initial few days postpartum. Education for patients and family members about the prevention, recognition, and treatment of hypoglycemia is important before, during, and after pregnancy to help to prevent and manage the risks of hypoglycemia. B, 14.11 Continuous glucose monitoring metrics may be used as an adjunct but should not be used as a substitute for self-monitoring of blood glucose to achieve optimal pre- and postprandial glycemic targets. A, 15.26 Women with a history of gestational diabetes mellitus should have lifelong screening for the development of type 2 diabetes or prediabetes every 13 years. Merrifield, VA 22116-7023. B. Women with type 1 diabetes have an increased risk of hypoglycemia in the first trimester and, like all women, have altered counterregulatory response in pregnancy that may decrease hypoglycemia awareness. Low-dose aspirin >100 mg is required (9799). It may be suited for pregnancy because the predict low glucose threshold for suspending insulin is in the range of premeal and overnight glucoses targets in pregnancy and may allow for more aggressive prandial dosing. For 80 years the ADA has been driving discovery and research to treat, manage and prevent diabetes, while working relentlessly for a cure. One study showed that care of preexisting diabetes in clinics that included diabetes and obstetric specialists improved care (28). Diabetes confers significantly greater maternal and fetal risk largely related to the degree of hyperglycemia but also related to chronic complications and comorbidities of diabetes. These associations with maternal oral glucose tolerance test (OGTT) results are continuous with no clear inflection points (37,50). 2021; 44 (Supplement 1):S15-S33. There are no adequately powered randomized trials comparing different fasting and postmeal glycemic targets in diabetes in pregnancy. The American Diabetes Association (ADA) Standards of Medical Care in Diabetes includes the ADA's current clinical practice recommendations and is intended to provide the components of diabetes care, general treatment goals and guidelines, and tools to evaluate quality of care. Health problems can occur when blood sugar is too high. This Guideline was approved November 13, 2016, and updated February 12, 2018. Oral agents may be an alternative in these women after a discussion of the known risks and the need for more long-term safety data in offspring. Those with elevated blood pressure measurements should have their measurements repeated on a . The 2023 Standards of Care in Diabetes includes all of ADA's current clinical practice recommendations and is intended to provide clinicians, patients, researchers, payers, and others with the components of diabetes care, general treatment goals, and tools to evaluate the quality of care. Long-acting, reversible contraception may be ideal for many women. There are no intervention trials in offspring of mothers with GDM. Due to physiological increases in red blood cell turnover, A1C levels fall during normal pregnancy (40,41). The U.S. Preventive Services Task Force recommends the use of low-dose aspirin (81 mg/day) as a preventive medication at 12 weeks of gestation in women who are at high risk for preeclampsia (96). Ongoing evaluation may be performed with any recommended glycemic test (e.g., annual A1C, annual fasting plasma glucose, or triennial 75-g OGTT using nonpregnant thresholds). Use of the CGM-reported mean glucose is superior to the use of estimated A1C, glucose management indicator, and other calculations to estimate A1C given the changes to A1C that occur in pregnancy (48).

Suggested citation: American Diabetes Association. Lower limits do not apply to diet-controlled type 2 diabetes. However, there is insufficient data regarding the benefits of aspirin in women with preexisting diabetes (98). There are no intervention trials in offspring of mothers with GDM. Both metformin and intensive lifestyle intervention prevent or delay progression to diabetes in women with prediabetes and a history of GDM. A cost-benefit analysis has concluded that this approach would reduce morbidity, save lives, and lower health care costs (100). A blood sugar level below 140 mg/dL (7.8 mmol/L) is usually considered within the standard range on a glucose challenge test, although this may vary by clinic or lab. 15. One study showed that care of preexisting diabetes in clinics that included diabetes and obstetric specialists improved care (27). A Insulin is the preferred agent for the management of type 2 diabetes in pregnancy. Insulin is the preferred treatment for type 2 diabetes in pregnancy. In these women, lifestyle intervention and metformin reduced progression to diabetes by 35% and 40%, respectively, over 10 years compared with placebo (112). 203: Chronic hypertension in pregnancy, Less-tight versus tight control of hypertension in pregnancy, Treatment of hypertension in pregnant women, Risks of statin use during pregnancy: a systematic review, Progression to type 2 diabetes in women with a known history of gestational diabetes: systematic review and meta-analysis, Incidence rate of type 2 diabetes mellitus after gestational diabetes mellitus: a systematic review and meta-analysis of 170,139 women, Healthful dietary patterns and type 2 diabetes mellitus risk among women with a history of gestational diabetes mellitus, Interpregnancy weight change and risk of adverse pregnancy outcomes: a population-based study, Diabetes Prevention Program Research Group, Prevention of diabetes in women with a history of gestational diabetes: effects of metformin and lifestyle interventions, The effect of lifestyle intervention and metformin on preventing or delaying diabetes among women with and without gestational diabetes: the Diabetes Prevention Program outcomes study 10-year follow-up, Peripartum management of glycemia in women with type 1 diabetes, Breastfeeding and the basal insulin requirement in type 1 diabetic women, Duration of lactation and incidence of type 2 diabetes, Does breastfeeding influence the risk of developing diabetes mellitus in children? . Both metformin and intensive lifestyle intervention prevent or delay progression to diabetes in women with prediabetes and a history of GDM. It means that, by working with your doctor, you can have a healthy pregnancy and a healthy baby. 2451 Crystal Drive,Suite 900 Therefore, all women with diabetes of childbearing potential should have family planning options reviewed at regular intervals to make sure that effective contraception is implemented and maintained. Low-dose aspirin >100 mg is required (109111). 14.1 Starting at puberty and continuing in all women with diabetes and reproductive potential, preconception counseling should be incorporated into routine diabetes care. Adjusting for BMI attenuated this association moderately, but not completely. Taking all of this into account, a target of <6% (42 mmol/mol) is optimal during pregnancy if it can be achieved without significant hypoglycemia. Rockville, MD, Agency for Healthcare Research and Quality, 2014 (Evidence Syntheses, No. American Diabetes Association; 14. In other words, short-term and long-term risks increase with progressive maternal hyperglycemia. Reflecting this physiology, fasting and postprandial monitoring of blood glucose is recommended to achieve metabolic control in pregnant women with diabetes.
