• #1 Fetal Macrosomia: What Is It, Causes & Complications

  https://my.clevelandclinic.org/health/diseases/17795-fetal-macrosomia

  Fetal macrosomia is a condition in which the fetus is larger than average (between 4,000 grams [8 pounds, 13 ounces] and 4,500 grams [9 pounds, 15 ounces]). There are many causes, including diabetes or obesity in the birth mother. […] Fetal macrosomia can cause serious complications during childbirth. There are many causes, but the two most important are uncontrolled diabetes and having obesity. You can reduce your risk of having a large baby by managing these conditions.

  Macrosomia refers to excessive fetal growth, typically defined by an absolute birth weight rather than gestational age. Historically, birth weights of 4,000 g or 4,500 g have been used to classify macrosomia, though no universal definition has been accepted. Maternal and neonatal risks increase significantly with higher birth weights. […] The following underlying factors have been associated with fetal macrosomia, which can be categorized as maternal or fetal etiologies: […] Maternal factors: Diabetes: Diabetes in pregnancy includes gestational diabetes (GDM), insulin-dependent, or drug-induced diabetes. Jordan Pederson, in 1920, hypothesized that maternal hyperglycemia is associated with fetal hyperinsulinemia and fetal hyperglycemia, which ultimately leads to the overutilization of glucose by the fetus and, hence, the abnormal increase in growth.

• #3 Macrosomia: Symptoms, Causes, and Complications

  https://www.healthline.com/health/macrosomia

  About 9 percent of all babies are born with macrosomia. […] Causes of this condition include: diabetes in the mother, obesity in the mother, genetics, a medical condition in the baby. […] Youre more likely to have a baby with macrosomia if you have diabetes before you get pregnant, or develop it during your pregnancy (gestational diabetes), start out your pregnancy obese, gain too much weight while pregnant, have high blood pressure during pregnancy, have had a previous baby with macrosomia, are more than two weeks past your due date, are over 35 years of age. […] Macrosomia can cause complications to both the mother and baby. […] Problems with the mother include: Injury to the vagina. As the baby is delivered, he or she can tear the mothers vagina or the muscles between the vagina and anus, the perineal muscles.

  Genetic factors and maternal conditions such as obesity or diabetes can cause fetal macrosomia. […] Sometimes it’s unknown what causes a baby to be larger than average. […] Fetal macrosomia is more likely to be a result of maternal diabetes, obesity or weight gain during pregnancy than other causes. If these risk factors aren’t present and fetal macrosomia is suspected, it’s possible that your baby might have a rare medical condition that affects fetal growth.

  https://www.medicalnewstoday.com/articles/fetal-macrosomia-definition-causes-complications-and-more

  Fetal macrosomia is a condition in which a newborn baby is much larger than average for their gestational age. […] There are various potential causes of fetal macrosomia. Some arise from the birthing parent, and others arise within the fetus. […] Causes of fetal macrosomia associated with the birthing parent include: Diabetes: If the birthing parent has diabetes, the fetus may overuse glucose, and this may trigger unusual growth. Types of diabetes that may cause fetal macrosomia include: insulin-dependent diabetes, chemically induced diabetes, gestational diabetes. […] According to one 2021 article, obesity in the birthing parent is associated with a four to 12 times increase in the risk of fetal macrosomia. This may be due to increased insulin resistance in the fetus. […] A person who is pregnant and worried about delivering a baby with fetal macrosomia should talk with a doctor or midwife. […] Fetal macrosomia may occur as a result of genetic conditions affecting the fetus or due to underlying health conditions, such as obesity or diabetes, in the birthing parent.

  Fetal macrosomia can cause serious birth complications. […] However, even if the cause of a birth defect is not a healthcare professional’s fault, the failure to diagnose the problem very much falls within the context of fetal macrosomia. […] According to the American College of Obstetricians and Gynecologists, or ACOG, causes for fetal macrosomia include: preexisting diabetes, a history of macrosomia, a mother’s pre-pregnancy weight, a large increase in maternal weight gain during pregnancy, multiparity, a male fetus, a gestational period longer than 40 weeks, the mother’s weight and height at birth, and a mother younger than 17 years old. […] The most serious of these causes is pregestational diabetes and gestational diabetes, which have a high association with fetal macrosomia. […] Studies show that women with untreated diabetes have an increased risk of delivering a baby that weighs more than 9 pounds 14 ounces. If gestational diabetes is ignored, the baby’s risk of fetal macrosomia could be as high as 20%.

  One of the primary risk factors of LGA births and macrosomia is poorly-controlled maternal diabetes, particularly gestational diabetes (GD), as well as preexisting type 2 diabetes mellitus (DM). The risk of having a macrosomic fetus is three times greater in mothers with diabetes than those without diabetes. […] Obesity prior to pregnancy and maternal weight gain above recommended guidelines during pregnancy are another key risk factor for macrosomia or LGA infants. It has been demonstrated that while maternal obesity and gestational diabetes are independent risk factors for LGA and macrosomia, they can act synergistically, with even higher risk of macrosomia when both are present. […] Genetics can also play a role in having an LGA baby and it is seen that taller, heavier parents tend to have larger babies. Genetic disorders of overgrowth (e.g. Beckwith-Wiedemann syndrome, Sotos syndrome, Perlman syndrome, Simpson-Golabi-Behmel syndrome) are often characterized by macrosomia.

This leads to increased fetal fat deposition, glycogen synthesis, and larger fetal size. Elevated fasting glucose levels may be more strongly associated with macrosomia. […] Genetic factors also contribute to fetal size. Taller (80th percentile or more) and heavier parents typically produce larger offspring. Women with short stature and obesity are at almost threefold higher risk for macrosomia compared with those of short stature with normal/overweight BMI.

  One of the primary risk factors of LGA births and macrosomia is poorly-controlled maternal diabetes, particularly gestational diabetes (GD), as well as preexisting type 2 diabetes mellitus (DM). The risk of having a macrosomic fetus is three times greater in mothers with diabetes than those without diabetes. […] Obesity prior to pregnancy and maternal weight gain above recommended guidelines during pregnancy are another key risk factor for macrosomia or LGA infants. It has been demonstrated that while maternal obesity and gestational diabetes are independent risk factors for LGA and macrosomia, they can act synergistically, with even higher risk of macrosomia when both are present. […] Genetics can also play a role in having an LGA baby and it is seen that taller, heavier parents tend to have larger babies. Genetic disorders of overgrowth (e.g. Beckwith-Wiedemann syndrome, Sotos syndrome, Perlman syndrome, Simpson-Golabi-Behmel syndrome) are often characterized by macrosomia.

  Infants whose weight is the 90th percentile for gestational age are classified as large for gestational age. Macrosomia is birthweight 4000 g in a term infant. The predominant cause is maternal diabetes. […] Other than genetically determined size, maternal diabetes mellitus is the major cause of large-for-gestational-age (LGA) infants. The large size results from the anabolic effects of high fetal insulin levels produced in response to excessive maternal blood glucose during gestation and sometimes increased caloric intake by the mother to compensate for glucose lost in urine. The less well controlled the mothers diabetes during pregnancy, the larger is the size of the fetus. Another contributing factor is maternal obesity.

  Most cases of fetal macrosomia occur when the fetus receives too many nutrients—in these cases, the mother will have conditions like diabetes (particularly gestational diabetes) or obesity. […] The major risk factors for macrosomia include: Maternal or gestational diabetes: Because diabetes increases the mother’s blood sugar and insulin levels, both gestational diabetes and type 2 diabetes can stimulate fetal growth and cause a baby to become very large for its gestational age. […] Maternal obesity: When a mother is obese or gains weight excessively during her pregnancy, additional nutrients may pass to the baby and stimulate fetal growth. […] Genetic overgrowth disorders: Disorders such as Sotos syndrome, a condition characterized by excessive growth during the first two to three years of life, increase the risk of macrosomia.

• #49 What Causes Fetal Macrosomia?

  https://www.icliniq.com/articles/newborn-and-baby/fetal-macrosomia

  Fetal macrosomia is used to describe a newborn whose birth weight is larger than the average. This condition is seen in 3 % to 15 % of all pregnancies. In fetal macrosomia, the baby weighs more than 4000 grams (8 pounds and 13 ounces), irrespective of the gestational age. Fetal macrosomia is more likely to develop if a person is obese. Pre or post-gestational diabetes, if not controlled well, can cause fetal macrosomia. The babies born to these mothers have greater amounts of body fat and bigger shoulders than those women who do not have diabetes. With each pregnancy, the risk of fetal macrosomia increases, and the average birth weight of the fetus increases by four ounces with each successive pregnancy. If one has already given birth to a larger baby, then they are more at risk of having another larger baby. If the pregnancy is more than two weeks than the expected due date (more than nine months), the chances for the baby to develop fetal macrosomia are higher. The age of women more than 35 years old are at risk of having a baby with fetal macrosomia. Generally, male infants weigh heavier than female infants. Most cases of macrosomia are in male infants. Certain genetic factors cause macrosomia if the mother is diabetic or obese during pregnancy. In diabetic mothers, the sugar passes through the placenta and gets deposited as fat, leading to a large baby. Maternal obesity, diabetes, excessive weight gain during pregnancy, male sex, and post-term pregnancy contribute to the risk of macrosomia.

  Obesity: Globally, there is a current epidemic of obesity. Obesity constitutes a significant risk for diabetes in all demographics. Precisely, maternal obesity is linked to a 4- to 12-fold increase in the prospect of fetal macrosomia. The standard metabolic basis of macrosomia is believed to be increased insulin resistance and hyperinsulinemia. […] Previous LGA infants: women with previous macrocosmic babies are at a 5- to 10-fold increased risk of another macrosomic baby. […] The primary underlying pathophysiology of macrosomia could be broadly divided into maternal and fetal risk factors. However, maternal hyperglycemia appears to be the most significant factor in the pathogenesis of macrosomia. […] Control of maternal hyperglycemia reduces the risk of macrosomia. Therefore, maternal glucose optimization is recommended for pregnancies complicated by diabetes.
