Introduction

Maternal obesity defined as a body mass index (BMI) of 30 or higher before pregnancy, has become a significant public health concern due to its increasing prevalence and the wide range of complications it can cause for both the mother and the fetus. The rising rates of obesity among women of childbearing age have profound implications for pregnancy outcomes and fetal development, necessitating a closer examination of the mechanisms and effects involved [1].

One of the most immediate impacts of maternal obesity on pregnancy outcomes is an increased risk of gestational diabetes mellitus (GDM). Obese women are more likely to develop GDM, a condition characterized by glucose intolerance that arises during pregnancy [2]. This condition not only poses immediate risks to the mother, such as preeclampsia and an increased likelihood of undergoing a cesarean section, but it also affects the fetus by increasing the risk of macrosomia (large for gestational age) and subsequent birth injuries. Babies born to mothers with GDM are also at a higher risk of developing metabolic disorders later in life, including obesity and type 2 diabetes, due to the intrauterine exposure to high glucose levels [3].

Additionally, maternal obesity is associated with a higher incidence of hypertensive disorders of pregnancy, including preeclampsia. This condition is characterized by high blood pressure and signs of damage to another organ system, often the kidneys [4]. Preeclampsia can lead to serious or even fatal complications for both mother and baby if left untreated. For the fetus, preeclampsia can result in poor growth, preterm birth, and, in severe cases, stillbirth. The exact mechanisms by which obesity contributes to preeclampsia are not fully understood, but it is believed to involve a combination of increased inflammation, oxidative stress, and insulin resistance, all of which are more prevalent in obese individuals [5].

Beyond these pregnancy-specific complications, maternal obesity also affects fetal development in several ways. One notable impact is the increased likelihood of congenital anomalies, particularly neural tube defects, cardiac defects, and orofacial clefts [6]. Research suggests that maternal obesity may interfere with the normal development of the fetus by altering the in utero environment, potentially due to the higher levels of inflammatory cytokines and insulin resistance associated with obesity. Moreover, obese women may have lower circulating levels of folic acid, an essential nutrient for fetal development, which further increases the risk of neural tube defects [7].

The impact of maternal obesity extends beyond pregnancy, influencing the long-term health of the offspring. Studies have shown that children born to obese mothers are more likely to develop obesity themselves, a phenomenon that can be partly attributed to genetic factors but also to epigenetic modifications induced by the intrauterine environment [8]. Maternal obesity can lead to changes in fetal gene expression, affecting the regulation of appetite and energy metabolism, which may predispose the child to obesity and metabolic syndrome later in life. This intergenerational transmission of obesity risk underscores the importance of addressing obesity before and during pregnancy to improve the health outcomes of both the mother and her child [9].

Efforts to mitigate the impacts of maternal obesity on pregnancy outcomes and fetal development focus on preconception counseling and weight management strategies. Healthcare providers are encouraged to discuss the risks associated with obesity with women of childbearing age and to promote healthy lifestyle changes, including a balanced diet and regular physical activity, even before conception. For women who are already pregnant, weight management should be approached with caution, as excessive weight loss is not recommended during pregnancy. Instead, the focus should be on healthy eating habits and appropriate weight gain according to gestational age and BMI [10].

Conclusion

Maternal obesity significantly impacts pregnancy outcomes and fetal development, increasing the risks of conditions like gestational diabetes, preeclampsia, congenital anomalies, and long-term metabolic disorders in the offspring. Addressing maternal obesity through early intervention and ongoing support is crucial for improving maternal and fetal health outcomes. Given the complexity and far-reaching effects of maternal obesity, a multidisciplinary approach involving obstetricians, nutritionists, and primary care providers is essential to support women before, during, and after pregnancy.
