Gestational diabetes is a significant health problem worldwide that is associated with immediate and lifelong consequences for the affected woman and her infant. Gestational diabetes increases the risk for pregnancy-related complications, such as induced labor, cesarean delivery, and preeclampsia. There is also an increased risk for neonatal complications, including large-for-gestational-age birth weight, shoulder dystocia, birth injuries, lung disease, jaundice, and hypoglycemia. Regardless of birth weight, neonates born to mothers with gestational diabetes have greater adiposity than do neonates born to mothers without obesity and with normal glucose tolerance, and they have a predilection toward obesity and obesity-related metabolic disorders, including T2D in childhood and adulthood. Similarly, women who develop gestational diabetes have an increased lifetime risk for T2D as well as an increased risk for cardiovascular disease even if they do not progress to T2D.

According to the International Diabetes Federation, 1 in 6 pregnancies is affected by gestational diabetes. Risk factors include higher age and BMI, previous history of gestational diabetes, a family history of T2D, and polycystic ovarian syndrome. Patients may have few, if any, symptoms of gestational diabetes, or they may mistake their symptoms for the normal side effects of pregnancy. Potential symptoms include blurred vision, tingling or numbness in the hands and/or feet, excessive thirst, frequent urination, sores that heal slowly, and excessive fatigue. 

The American Diabetes Association (ADA) states that the treatment of gestational diabetes should include medical nutrition therapy, physical activity, and weight management, depending on pregestational weight. Glucose monitoring is essential: Patients should aim for fasting glucose < 95 mg/dL (5.3 mmol/L) and either 1-hour postprandial glucose < 140 mg/dL (7.8 mmol/L) or 2-hour postprandial glucose < 120 mg/dL (6.7 mmol/L). According to the ADA, insulin should be added to lifestyle modifications if needed to achieve glycemic targets. Metformin and glyburide are not recommended as first-line agents because both cross the placenta to the fetus. Long-term safety data are not available for the use of other oral and noninsulin injectable glucose-lowering medications during pregnancy.

This patient's clinical presentation of weight gain and associated symptoms are most closely related to a diagnosis of obesity. In addition, her laboratory findings are consistent with common obesity complications, including prediabetes and dyslipidemia, and her blood pressure is borderline high. 

Obesity is a chronic, multifactorial disease with a complex pathogenesis comprising of genetic, biological, psychosocial, socioeconomic, and environmental factors. It is a heterogeneous disease characterized by a dysfunction of the normal pathways and mechanisms that are involved in body fat regulation (often referred to as weight regulation), which may lead to variable presentation and complications. According to the US Centers for Disease Control and Prevention, the highest age-adjusted prevalence of obesity is seen in non-Hispanic Black adults (49.9%), followed by Hispanic adults (45.6%), non-Hispanic White adults (41.4%), and non-Hispanic Asian adults (16.1%).

Epidemiologic studies have defined obesity as a BMI > 30, which is then subclassified into class 1 (BMI of 30-34.9), class 2 (BMI of 35-39.9), or class 3 (BMI ≥ 40) obesity. Though BMI is widely used to evaluate and classify obesity, it mainly represents general adiposity and can be confounded by excessive muscle mass or frailty. Guidelines from the American Diabetes Association state that in addition to weight and BMI, clinicians should consider weight distribution (including predisposition for central/visceral adipose deposition) and weight gain pattern and trajectory because these can help guide risk stratification and treatment options.

Increasingly, evidence supports visceral adiposity, or abdominal obesity, as a marker of cardiovascular risk. Abdominal obesity has been shown to be a strong independent predictor of mortality. On its own, BMI is an insufficient biomarker of abdominal obesity. Not all individuals with obesity have a central distribution of their weight; some individuals may have central obesity without meeting the criteria for the BMI definition of obesity. This can lead to misclassification and underdiagnosis of health risks in clinical practice. Consequently, numerous organizations and expert panels have recommended that waist circumference be measured along with BMI, specifically when the BMI < 35. Measurement of both BMI and waist circumference provides valuable opportunities to counsel patients regarding their risk for cardiovascular disease and other complications of obesity. Waist-to-hip ratio has also been shown to be a stronger predictor for mortality compared with BMI; however, it is rarely measured in clinical practice.

Although rarely performed outside of research settings, measurement of epicardial and pericardial fat via CT is also emerging as a potentially useful approach for informing predictive and precision medicine strategies. Recently, the Jackson Heart Study showed pericardial and visceral fat volumes were associated with incident heart failure, particularly heart failure with preserved ejection fraction, and all-cause mortality among Black participants even after adjusting for age, sex, education, and smoking status. Another recent study showed an increased risk of heart failure, particularly heart failure with preserved ejection fraction, among men and women with high pericardial fat volume. The Multi-Ethnic Study of Atherosclerosis showed that pericardial fat was associated with a higher risk of all-cause cardiovascular disease, hard atherosclerotic cardiovascular disease, and heart failure. Epicardial fat is directly correlated with BMI, visceral adiposity, and waist circumference.

Best practices for the management of obesity begin with recognizing and treating it as a complex chronic disease rather than the result of an individual's lifestyle choices. According to a 2020 joint international consensus statement for ending the stigma of obesity, the assumption that choosing to eat less and/or exercise more can entirely prevent or reverse obesity is contradicted by a definitive body of biological and clinical evidence that shows obesity results primarily from a complex combination of genetic, epigenetic, and environmental factors. When diagnosing patients with obesity, it may be helpful for clinicians to acknowledge that the term obesity is often perceived as an undesirable term because it has been associated with stigma but that it is in fact a clinical diagnosis, not a judgement. Many patients prefer the neutral term unhealthy weight over obesity.

As with other chronic diseases, individualized treatment and long-term support along with shared decision-making are essential for optimizing outcomes. Key components of obesity management include diet, exercise, and behavioral modification. In addition, an increasing array of pharmacologic therapies are also showing unprecedented efficacy for weight management, including several drugs that are also approved for the management of type 2 diabetes. In particular, the glucagonlike peptide 1 (GLP-1) agonists, semaglutide and liraglutide, and the novel glucose-dependent insulinotropic polypeptide (GIP)–GLP-1 receptor agonist, tirzepatide have been associated with significant weight loss. Semaglutide and liraglutide have been US Food and Drug Administration (FDA)–approved for chronic weight management and tirzepatide was granted fast track designation for the treatment of obesity by the FDA in October 2022. These drugs may also help to prevent the progression of prediabetes to diabetes. For individuals with severe obesity, metabolic and bariatric surgery is an effective treatment option that is associated with clinically significant and relatively sustained weight reduction in addition to significant amelioration of related complications.
