It means that, by working with your doctor, you can have a healthy pregnancy and a healthy baby. Bethesda, MD, National Library of Medicine. 2021; 44 (Supplement 1):S15-S33. In two RCTs of metformin use in pregnancy for polycystic ovary syndrome, follow-up of 4-year-old offspring demonstrated higher BMI and increased obesity in the offspring exposed to metformin (81,82). The A1C target in a given patient should be achieved without hypoglycemia, which, in addition to the usual adverse sequelae, may increase the risk of low birth weight (46). Glyburide failed to be found noninferior to insulin based on a composite outcome of neonatal hypoglycemia, macrosomia, and hyperbilirubinemia (74). A recent meta-analysis concluded that metformin exposure resulted in smaller neonates with an acceleration of postnatal growth, resulting in higher BMI in childhood (82). Members of the ADA Professional Practice Committee, a multidisciplinary expert committee (https://doi.org/10.2337/dc21-SPPC), are responsible for updating the Standards of Care annually, or more frequently as warranted. Concentrations of glyburide in umbilical cord plasma are approximately 5070% of maternal levels (70,71). Therefore, all women should be screened as outlined in Section 2, Classification and Diagnosis of Diabetes (https://doi.org/10.2337/dc22-S002). A major barrier to effective preconception care is the fact that the majority of pregnancies are unplanned. Complications of gestational diabetes. The objective of the Joslin Guideline for Detection and Management of Diabetes in Pregnancy is to support clinical practice and to influence clinical behaviors in order to improve clinical outcomes and assure that patient expecta- tions are reasonable and informed. Most women who have gestational diabetes deliver healthy babies. 14.1 Starting at puberty and continuing in all women with diabetes and reproductive potential, preconception counseling should be incorporated into routine diabetes care. More recently, glyburide failed to be found noninferior to insulin based on a composite outcome of neonatal hypoglycemia, macrosomia, and hyperbilirubinemia (66). A Other oral and noninsulin injectable glucose-lowering medications lack long-term safety data. B, 15.27 Women with a history of gestational diabetes mellitus should seek preconception screening for diabetes and preconception care to identify and treat hyperglycemia and prevent congenital malformations. There was heterogeneity in the types of effective exercise (aerobic, resistance, or both) and duration of exercise (2050 min/day, 27 days/week of moderate intensity) (65). A meta-analysis of 32 RCTs evaluating the effectiveness of telehealth visits for GDM demonstrated reduction of incidences of cesarean delivery, neonatal hypoglycemia, premature rupture of membranes, macrosomia, pregnancy-induced hypertension or preeclampsia, preterm birth, neonatal asphyxia, and polyhydramnios compared with standard in-person care (57). Here's what these new updates mean, including your options for first-line glucose-lowering therapies, when you should be screened for diabetes, the expanded use of diabetes care technology, and more. While individual RCTs support limited efficacy of metformin (67,68) and glyburide (69) 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 (35). Introduction: Gestational diabetes mellitus (GDM) is a major public health problem, affecting about one in every six pregnancies globally. 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. However, ACE inhibitors and angiotensin receptor blockers should be stopped as soon as possible in the first trimester to avoid second and third trimester fetopathy (20). Glycemic control is often easier to achieve in women with type 2 diabetes than in those with type 1 diabetes but can require much higher doses of insulin, sometimes necessitating concentrated insulin formulations. Young children usually need less than 15 grams of carbs to fix a low blood glucose level: Infants may need 6 grams, toddlers may need 8 grams, and small children may need 10 grams. Observational studies show an increased risk of diabetic embryopathy, especially anencephaly, microcephaly, congenital heart disease, renal anomalies, and caudal regression, directly proportional to elevations in A1C during the first 10 weeks of pregnancy (3).

PDF ACOG PRACTICE BULLETIN - SCL Health Breastfeeding may also confer longer-term metabolic benefits to both mother (127) and offspring (128). Members of the ADA Professional Practice Committee, a multidisciplinary expert committee (https://doi.org/10.2337/dc22-SPPC), are responsible for updating the Standards of Care annually, or more frequently as warranted. Accessed 21 June 2020. There are no adequate data on optimal weight gain versus weight maintenance in women with BMI >35 kg/m2. (Evidence Syntheses, No. Complications in your baby can be caused by gestational diabetes, including: C. Pregnancy in women with normal glucose metabolism is characterized by fasting levels of blood glucose that are lower than in the nonpregnant state due to insulin-independent glucose uptake by the fetus and placenta and by mild postprandial hyperglycemia and carbohydrate intolerance as a result of diabetogenic placental hormones. Clinical trials have not evaluated the risks and benefits of achieving these targets, and treatment goals should account for the risk of maternal hypoglycemia in setting an individualized target of <6% (42 mmol/mol) to <7% (53 mmol/mol). However, ACE inhibitors and angiotensin receptor blockers should be stopped as soon as possible in the first trimester to avoid second and third trimester fetopathy (21). 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. 112). See PREGNANCY AND ANTIHYPERTENSIVE MEDICATIONS in Section 10 Cardiovascular Disease and Risk Management (https://doi.org/10.2337/dc21-S010) for more information on managing blood pressure in pregnancy. While many providers prefer insulin pumps in pregnancy, it is not clear that they are superior to multiple daily injections (101,102). Observational studies in preexisting diabetes and pregnancy show the lowest rates of adverse fetal outcomes in association with A1C <66.5% (4248 mmol/mol) early in gestation (46,39). Mount Sinai Hospital, Canada. Recommended weight gain during pregnancy for women with overweight is 1525 lb and for women with obesity is 1020 lb (58). Diabetes has brought us together. 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. Insulin sensitivity then returns to prepregnancy levels over the following 12 weeks. PDF Gestational Diabetes Guideline - Kaiser Permanente A review of current evidence, 2021 by the American Diabetes Association, Readers may use this article as long as the work is properly cited, the use is educational and not for profit, and the work is not altered. Insulin use should follow the guidelines below. A, 15.3 Preconception counseling should address the importance of achieving glucose levels as close to normal as is safely possible, ideally A1C <6.5% (48 mmol/mol), to reduce the risk of congenital anomalies, preeclampsia, macrosomia, preterm birth, and other complications. The insulin requirement levels off toward the end of the third trimester with placental aging. However, due to the potential for growth restriction or acidosis in the setting of placental insufficiency, metformin should not be used in women with hypertension or preeclampsia or at risk for intrauterine growth restriction (88,89). Diabetes mellitus (also called "diabetes") is a condition in which too much glucose (sugar) stays in the blood instead of being used for energy. A systematic review and meta-analysis of observational studies of preconception care for women with preexisting diabetes demonstrated lower A1C and reduced risk of birth defects, preterm delivery, perinatal mortality, small-for-gestational-age births, and neonatal intensive care unit admission (8). Readers who wish to comment on the Standards of Care are invited to do so at professional.diabetes.org/SOC. For a detailed description of ADA standards, statements, and reports, as well as the evidence-grading system for ADA's clinical practice recommendations, please refer to the Standards of Care Introduction (https://doi.org/10.2337/dc21-SINT). 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. A Insulin is the preferred agent for the management of type 2 diabetes in pregnancy. Women with GDM have a 10-fold increased risk of developing type 2 diabetes compared with women without GDM (107). However, metformin readily crosses the placenta, resulting in umbilical cord blood levels of metformin as high or higher than simultaneous maternal levels (78,79). https://doi.org/10.2337/dc22-S015. However, metformin readily crosses the placenta, resulting in umbilical cord blood levels of metformin as high or higher than simultaneous maternal levels (70,71). Preconception counseling resources tailored for adolescents are available at no cost through the American Diabetes Association (ADA) (16). 11 Once women achieve and maintain good glycemic control, the frequency of testing can be decreased. Adjusting for BMI attenuated this association moderately, but not completely. However, in women with diabetes, hyperglycemia occurs if treatment is not adjusted appropriately. If both the fasting plasma glucose (126 mg/dL [7.0 mmol/L]) and 2-h plasma glucose (200 mg/dL [11.1 mmol/L]) are abnormal in a single screening test, then the diagnosis of diabetes is made. B, 15.11 Continuous glucose monitoring metrics may be used in addition to but should not be used as a substitute for self-monitoring of blood glucose to achieve optimal pre- and postprandial glycemic targets. Counseling on the specific risks of obesity in pregnancy and lifestyle interventions to prevent and treat obesity, including referral to a registered dietitian nutritionist (RD/RDN), is recommended when indicated. 1):S200S210. Atenolol is not recommended, but other -blockers may be used, if necessary. Both metformin and intensive lifestyle intervention prevent or delay progression to diabetes in women with prediabetes and a history of GDM. Metformin was associated with a lower risk of neonatal hypoglycemia and less maternal weight gain than insulin in systematic reviews (72,7577). A recent meta-analysis concluded that metformin exposure resulted in smaller neonates with acceleration of postnatal growth resulting in higher BMI in childhood (74). Reflecting this physiology, fasting and postprandial monitoring of blood glucose is recommended to achieve metabolic control in pregnant women with diabetes.

Chronic diuretic use during pregnancy is not recommended as it has been associated with restricted maternal plasma volume, which may reduce uteroplacental perfusion (105). If these targets cannot be met and the majority of fasting and/or postprandial values are elevated, then pharmacotherapy is recommended. In one study, insulin requirements in the immediate postpartum period are roughly 34% lower than prepregnancy insulin requirements (125). DKA carries a high risk of stillbirth. 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. In normal pregnancy, blood pressure is lower than in the nonpregnant state. There are opportunities to educate all women and adolescents of reproductive age with diabetes about the risks of unplanned pregnancies and about improved maternal and fetal outcomes with pregnancy planning (8). Insulin should be added if needed to achieve glycemic targets. However, lactation can increase the risk of overnight hypoglycemia, and insulin dosing may need to be adjusted. There are no data to support the use of TIR in women with type 2 diabetes or GDM. Not only is the prevalence of type 1 diabetes and type 2 diabetes increasing in women of reproductive age, but there is also a dramatic increase in the reported rates of gestational diabetes mellitus.

Metformin was associated with a lower risk of neonatal hypoglycemia and less maternal weight gain than insulin in systematic reviews (65,6769). Sulfonylureas are known to cross the placenta and have been associated with increased neonatal hypoglycemia. More than 122 million Americans have diabetes or prediabetes and are striving to manage their lives while living with the disease. .
