• #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]). […] While fetal macrosomia is unpredictable, promoting good health and a healthy pregnancy can help prevent it. […] Delivering a large baby can be difficult, with more risk for vaginal tears or problems pushing your baby out. […] If your healthcare provider thinks that your baby is very big (more than 11 pounds, or more than 10 pounds if you have diabetes), a cesarean birth (C-section) may be the safest option. […] Having a large baby can increase your risk for certain complications during childbirth. […] Your healthcare provider will monitor your labor for signs of shoulder dystocia, as well as a plan of action should it happen.

  Treatment for macrosomia focuses on controlling any underlying health conditions you have like diabetes or obesity. […] In some cases, a C-section is recommended to reduce the chances of a complication. […] Its important to know that delivering your baby early doesnt seem to reduce complications, so scheduling a delivery prior to 39 weeks isnt recommended unless there are other medical complications besides your babys size. […] Fetal macrosomia is often unpredictable. […] Promoting good health and a healthy pregnancy can improve the odds: […] If you have diabetes, take appropriate steps to manage it. […] You can reduce your risk of having a large baby by managing these conditions.

  https://www.mayoclinic.org/diseases-conditions/fetal-macrosomia/symptoms-causes/syc-20372579

  The term „fetal macrosomia” is used to describe a newborn who’s much larger than average. […] Fetal macrosomia may complicate vaginal delivery and can put the baby at risk of injury during birth. Fetal macrosomia also puts the baby at increased risk of health problems after birth. […] 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. […] Possible maternal complications of fetal macrosomia might include: Labor problems. Fetal macrosomia can cause a baby to become wedged in the birth canal (shoulder dystocia), sustain birth injuries, or require the use of forceps or a vacuum device during delivery (operative vaginal delivery). Sometimes a C-section is needed. […] You might not be able to prevent fetal macrosomia, but you can promote a healthy pregnancy. Research shows that exercising during pregnancy and eating a low-glycemic diet can reduce the risk of macrosomia.

• #3 Macrosomia: Practice Essentials, Background, Pathophysiology

  https://emedicine.medscape.com/article/262679-overview

  The term macrosomia is used to describe a newborn with an excessive birth weight. An accurate diagnosis of fetal macrosomia can be made only by measuring birth weight after delivery; therefore, the condition is confirmed only retrospectively, ie, after delivery of the neonate. Fetal macrosomia has been defined in several different ways, including birth weight greater than 4000 g or 4500 g (8 lb 13 oz or 9 lb 15 oz) or greater than 90% for gestational age. […] Attempts at perinatal diagnosis of macrosomia have proven difficult and are often inaccurate. This article defines macrosomia and reviews clinical and diagnostic modalities currently used to screen for pregnancies at the greatest risk for macrosomia with some degree of accuracy. Maternal, fetal, and neonatal consequences of macrosomia are also discussed, with specific attention to the potential etiology of macrosomia.

• #3 Macrosomia: Practice Essentials, Background, Pathophysiology

  https://emedicine.medscape.com/article/262679-overview

  Factors associated with fetal macrosomia include genetics; duration of gestation; presence of gestational diabetes; high pre-pregnancy body mass index (BMI); excessive gestational weight gain; and class A, B, and C diabetes mellitus. […] Despite the identification and characterization of risk factors, no combination of these risk factors can predict macrosomia accurately enough to be used clinically. Much of the birth weight variation remains unexplained, and most macrosomic infants do not have identifiable risk factors. Finally, macrosomia is reportedly associated with neonatal morbidity, neonatal injury, maternal injury, and cesarean delivery. […] The pathophysiology of macrosomia is related to the associated maternal or fetal condition that accounts for its development. In general, poorly controlled diabetes, maternal obesity, and excessive maternal weight gain are all associated with macrosomia and have intermittent periods of hyperglycemia in common. […] A large for gestational age fetus in a diabetic mother may indicate poor glucose control. These infants are at increased risk of intrauterine death and thus require close monitoring and antepartum fetal testing.

• #4 Fetal macrosomia – UpToDate

  https://www.uptodate.com/contents/fetal-macrosomia

  Fetal macrosomia refers to growth beyond a specific threshold, regardless of gestational age. In high income countries, the most commonly used threshold is weight above 4500 g (9 lb 15 oz), but weight above 4000 g (8 lb 13 oz) is also commonly used. A grading system has been suggested: grade 1 for infants 4000 to 4499 g, grade 2 for 4500 to 4999 g, and grade 3 for over 5000 g. This system may be useful at term for decision-making regarding forceps- or vacuum-assisted vaginal birth. […] Macrosomia is associated with an increased risk of several complications, particularly maternal and/or fetal trauma during birth and neonatal hypoglycemia and respiratory problems. Long-term adverse effects in these offspring include increased risks for obesity and insulin resistance. […] Obstetric and pediatric management are discussed separately.

  Fetal macrosomia increases the risk that your uterine muscles won’t properly contract after you give birth (uterine atony). This can lead to potentially serious bleeding after delivery. […] Possible complications of fetal macrosomia for your baby might include: Lower than normal blood sugar level. A baby diagnosed with fetal macrosomia is more likely to be born with a blood sugar level that’s lower than normal. […] Research shows that exercising during pregnancy and eating a low-glycemic diet can reduce the risk of macrosomia. […] Fetal macrosomia can’t be diagnosed until after the baby is born and weighed. […] Your health care provider might recommend a C-section if: You have diabetes. If you had diabetes before pregnancy or you develop gestational diabetes and your health care provider estimates that your baby weighs 9 pounds, 15 ounces (4,500 grams) or more, a C-section might be the safest way to deliver your baby.

  If any of these risk factors are present during pregnancy, the mother should be carefully monitored: Diabetes gestational or Type 1 or Type 2. […] Mothers with diabetes are ten times more likely to have macrosomic babies, so doctors should be especially careful to monitor them. […] If a baby has macrosomia and the doctor does not diagnose it before birth, that can cause serious problems during delivery. […] When a baby is properly diagnosed in advance, the doctor can discuss the risks and benefits of a vaginal delivery versus a C-section with the mother. […] But when a baby with macrosomia is undiagnosed and delivered vaginally, there is a risk the baby may get injured or stuck in the birth canal, which can cause birth injuries that may not have happened with a proper diagnosis.

  Fetal macrosomia is a condition that occurs during pregnancy where the baby becomes abnormally large for its gestational stage. […] Fetal macrosomia complicates as many as 50 percent of pregnancies in women with gestational diabetes and 40 percent of pregnancies complicated by type 1 and type 2 diabetes, including some women treated with intensive glycemic control. […] Diligent monitoring and timely diagnosis of fetal macrosomia are therefore very important. […] The most serious complication of fetal macrosomia is shoulder dystocia. […] Diagnosis of fetal macrosomia also involves the recognition of various symptoms and risk factors by doctors in earlier stages of pregnancy. […] Recognition and timely diagnosis of fetal macrosomia is critical in preventing delivery complications. […] If timely diagnosed, fetal macrosomia can usually be handled safely by an early C-section delivery.

  Fetal macrosomia is a serious condition in pregnancy. It requires close monitoring and frequent visits to the doctors office. […] The most common cause of fetal macrosomia is diabetes, especially gestational diabetes. […] If a woman has obesity before she becomes pregnant, this also puts her fetus at risk for fetal macrosomia. […] To decrease the risk of an LGA baby, the mother with obesity has a few options. […] A large fetal size is not always preventable. […] When the mother has high blood sugar, it crosses the placenta to reach the fetus. […] Early education and treatment are crucial in reducing complications from fetal macrosomia. […] A birthing plan before going into the hospital is a good idea. […] According to the American College of Nurse-Midwives, prenatal care from a midwife can reduce the need for a C-section. […] However, fetal macrosomia meets the definition of a high-risk pregnancy.

  https://emedicine.medscape.com/article/262679-treatment

  In patients with poorly controlled diabetes resulting in macrosomia, consultation with a maternal fetal medicine specialist to obtain better control may be useful. […] Pregestational obesity and excessive gestational weight gain in pregnancy are two of the strongest predictors of macrosomia at birth; therefore, a possible intervention to prevent macrosomia may be nutrition education and an exercise program. […] Dietary and weight gain guideline education should be provided for obese patients of patients experiencing excessive gestational weight gain as these are associated with macrosomia, gestational diabetes, cesarean delivery, and preeclampsia. […] ACOG recommends that women without any contraindications should be encouraged to participate in aerobic and strength conditioning exercises during pregnancy to reduce the risk of macrosomia.

  Cesarean delivery to reduce the risk associated with macrosomia may place the mother at risk, and subsequent pregnancies are at risk of uterine dehiscence before or during the onset of labor. […] Decision making regarding delivery should be individualized to the patient, taking into account risks and benefits of both macrosomia and other delivery factors such as surgical risks, including implications for future childbearing, and the neonatal risks of early term delivery. […] The obstetrician involved in the care of a macrosomic infant must be familiar with procedures that release a shoulder dystocia at delivery. […] Because macrosomic infants are at increased risk of cesarean delivery, the provider must be capable of performing a cesarean delivery or must have backup help available in case cesarean delivery is necessary.

  https://emedicine.medscape.com/article/262679-treatment

  Induction of labor for presumed fetal macrosomia has in recent history been discouraged due to unclear benefit. […] Induction of labor was associated with reduced risk of shoulder dystocia; however, the study was underpowered to detect a difference in brachial plexus injury and none occurred in either group. […] Early term or 39-week induction of labor can reduce rates of macrosomia compared with expectant management, and therefore may decrease the complications of macrosomia. […] Even though the risk of fetal and maternal morbidity increases with macrosomia, most deliveries of macrosomic infants are uncomplicated. […] The American College of Obstetricians and Gynecologists (ACOG) continues to recommend against delivery before 39 0/7 weeks unless medically indicated. […] Therefore, induction of labor for suspected macrosomia before 39 0/7 weeks of gestation is not recommended by ACOG owing to insufficient evidence that reducing the risk of shoulder dystocia outweighs the risks associated with early delivery.

• #10 ACOG Issues Guidelines on Fetal Macrosomia | AAFP

  https://www.aafp.org/pubs/afp/issues/2001/0701/p169.html

  The Committee on Practice BulletinsObstetrics of the American College of Obstetricians and Gynecologists (ACOG) has issued new clinical management guidelines on fetal macrosomia. ACOG Practice Bulletin No. 22, which replaces Technical Bulletin No. 159 issued in September 1991, appears in the November 2000 issue of Obstetrics and Gynecology. These guidelines discuss risk factors and complications, and suggest clinical management for the pregnancy with suspected fetal macrosomia. […] Weighing the newborn after delivery is the only way to accurately diagnose macrosomia, because the prenatal diagnostic methods (assessment of maternal risk factors, clinical examination and ultrasonographic measurement of the fetus) remain imprecise. […] According to the ACOG committee, the risk factors (excluding preexisting diabetes mellitus) for fetal macrosomia, in decreasing order of importance, are as follows: a history of macrosomia, maternal prepregnancy weight, weight gain during pregnancy, multiparity, male fetus, gestational age more than 40 weeks, ethnicity, maternal birth weight, maternal height, maternal age younger than 17 years and a positive 50-g glucose screen with a negative result on the three-hour glucose tolerance test.

• #10 ACOG Issues Guidelines on Fetal Macrosomia | AAFP

  https://www.aafp.org/pubs/afp/issues/2001/0701/p169.html

  ACOG emphasizes that an increased risk of cesarean delivery is the primary maternal risk factor associated with macrosomia. […] Clinical interventions for the treatment of suspected macrosomia (in pregnant women without diabetes) have not been reported. […] Excessive weight gain during pregnancy is associated with fetal macrosomia, and results from large cohort studies confirm this. […] The role of cesarean delivery in suspected fetal macrosomia remains controversial. […] In cases of term patients with suspected fetal macrosomia, current evidence does not support early induction of labor. […] Midpelvic operative vaginal delivery is the most important consideration for labor and delivery in the case of suspected fetal macrosomia. […] The ACOG committee provides the following recommendations for the management of fetal macrosomia: The diagnosis of fetal macrosomia is imprecise. For suspected fetal macrosomia, the accuracy of estimated fetal weight using ultrasound biometry is no better than that obtained with clinical palpation (Leopold’s maneuvers).

• #10 ACOG Issues Guidelines on Fetal Macrosomia | AAFP

  https://www.aafp.org/pubs/afp/issues/2001/0701/p169.html

  Suspected fetal macrosomia is not an indication for induction of labor, because induction does not improve maternal or fetal outcomes. […] Labor and vaginal delivery are not contraindicated for women with estimated fetal weights up to 5,000 g in the absence of maternal diabetes. […] With an estimated fetal weight more than 4,500 g, a prolonged second stage of labor or arrest of descent in the second stage is an indication for cesarean delivery. […] Although the diagnosis of fetal macrosomia is imprecise, prophylactic cesarean delivery may be considered for suspected fetal macrosomia with estimated fetal weights of more than 5,000 g in pregnant women without diabetes and more than 4,500 g in pregnant women with diabetes.

• #12 Fetal Macrosomia: Symptoms and Care

  https://www.medicoverhospitals.in/diseases/fetal-macrosomia/

  Fetal macrosomia is a condition characterized by a newborn with excessive birth weight, typically defined as weighing more than 8 pounds, 13 ounces (4,000 grams), regardless of gestational age. This condition presents numerous challenges and risks for both the mother and the child, making it crucial to comprehend the potential causes, risk factors, symptoms, and treatment options. […] Fetal macrosomia is not a disease but rather a descriptive term used when a baby is significantly larger than average. It can lead to complications during delivery and postpartum challenges for both the mother and the newborn. Understanding the underlying causes and associated risks is essential for managing and potentially mitigating these complications. […] Maternal diabetes, particularly gestational diabetes, is a significant contributor to fetal macrosomia. Elevated blood sugar levels can result in increased fetal insulin production, leading to excessive growth. Other maternal health conditions, such as obesity and excessive weight gain during pregnancy, can also increase the risk of delivering a macrosomic baby.

• #14 Management of Suspected Fetal Macrosomia | AAFP

  https://www.aafp.org/pubs/afp/issues/2001/0115/p302.html

  The medical literature confirms that prediction of fetal macrosomia is difficult. Ultrasound estimation of fetal weight adds little additional useful information. What clinicians really want to predict is not macrosomia, per se, but the serious complications that physicians mistakenly associate as occurring only with macrosomia, such as brachial plexus injury or shoulder dystocia. Such complications, however, are not determined by birth weight alone, but by a complex and poorly understood relationship between fetal and maternal anatomy and other factors. […] For almost all macrosomic pregnancies including diabetic mothers, previous deliveries with shoulder dystocia, or women considering VBACs, expectant management with vigilance for evidence of fetopelvic disproportion will have optimal results.

• #14 Management of Suspected Fetal Macrosomia | AAFP

  https://www.aafp.org/pubs/afp/issues/2001/0115/p302.html

  Management strategies for suspected fetal macrosomia include elective cesarean section and early induction of labor. […] Elective cesarean section for suspected macrosomia has been proposed as a way to spare the parturient an unproductive labor and to prevent birth trauma. Unfortunately, the difficulties in predicting macrosomia and the favorable outcome for most women who undergo a trial of labor imply that a large number of unnecessary cesarean sections would have to be performed to prevent a single bad outcome in the pregnancy complicated by suspected fetal macrosomia. […] Given that the fetus continues to gain about 230 g (8.1 oz) per week after the 37th week, elective induction of labor before or near term has been suggested to prevent macrosomia and its complications. However, observational studies suggest that induction actually increases the cesarean section rate without favorably altering perinatal outcomes.

  Fetal macrosomia and LGA often do not present with noticeable patient symptoms. Important signs include large fundal height (uterus size) and excessive amniotic fluid (polyhydramnios). […] Evaluating an infant for macrosomia or LGA can help identify risks associated with their birth, including labor complications of both the parent and the child, potential long-term health complications of the child, and infant mortality. […] Complications of the pregnant mother include: emergency cesarean section, postpartum hemorrhage, and obstetric anal sphincter injury. Compared to pregnancies without macrosomia, pregnant women giving birth to newborns weighing between 4,000 grams and 4,500 grams are at two times greater risk of complications, and those giving birth to infants over 4,500 grams are at three times greater risk.

  Fetal macrosomia refers to a baby who is larger than average for their gestational age. In general, a baby weighing more than 4kg (8 pounds) at birth is considered to have macrosomia. This can make vaginal delivery more difficult and put the baby at risk of injury during birth. […] Fetal macrosomia is typically diagnosed during prenatal care through ultrasound imaging. Ultrasound measurements can estimate fetal weight and can detect if the fetus is growing too quickly. Other diagnostic tests that may be performed include fetal echocardiography and fetal blood sampling. […] There are several treatment options available depending on the severity of the condition. These may include: Inducing labor before the due date: If the fetus is estimated to be larger than average, inducing labor before the due date may be recommended to reduce the risk of complications during delivery. Caesarean delivery: If the fetus is estimated to be significantly larger than average or if the mother has diabetes, caesarean delivery may be recommended to reduce the risk of complications during delivery. Blood glucose monitoring and control: For mothers with diabetes, controlling blood glucose levels during pregnancy can help prevent fetal macrosomia.

• #22 Management of neonatal complications of macrosomia: A case report at a tertiary hospital in a developing country

  https://pmc.ncbi.nlm.nih.gov/articles/PMC8777164/

  Fetal macrosomia can present with numerous complications. We report a case of a term baby girl with a birthweight of 5.31 kg admitted with respiratory distress and suffered several complications of macrosomia. There is a need to closely monitor neonates for early diagnosis and management of complications of macrosomia. […] Fetal macrosomia is common among neonates and its proper management improves the outcome of these neonates. […] Our patient weighed 5.3 kg at birth, which is 97th percentile of the expected birthweight, and this alone should prompt a reason for admission to a neonatal unit for early identification of complications and monitoring. […] Even without complications, macrosomic babies should be admitted for monitoring, especially of their blood sugars as they are at risk of hypoglycemia, a common complication of macrosomia.

  A LGA newborn is one weighs more than 4,000 g, is above the 90th percentile, or is two standard deviations above the mean. […] The condition most commonly linked to a newborn being large-for-gestational-age (LGA) or macrosomic is maternal diabetes. This includes both gestational diabetes and pre-existing diabetes (type 1 or type 2). […] Recognizing the link between maternal diabetes and fetal macrosomia is crucial for proper management during pregnancy and delivery. Macrosomic infants are at higher risk for complications such as birth injuries (e.g., shoulder dystocia), hypoglycemia, and respiratory distress after birth. […] Monitor the infant’s blood glucose levels closely after birth to detect and treat hypoglycemia. […] Assess the infant for signs of birth trauma, such as shoulder dystocia, clavicle fractures, or brachial plexus injury.

  The role of cesarean delivery in suspected fetal macrosomia remains controversial. While the risk of birth trauma with vaginal delivery is higher with increased birth weight, the mode of delivery by cesarean section reduces but does not eliminate this risk. Most babies with fetal macrosomia can be delivered vaginally. However, doctors recommend Cesarean delivery in certain cases. […] Even though there are some cases in which fetal macrosomia occurs for no apparent reason, pregnant women can help reduce the chances by watching weight gain, controlling diabetes, and keeping all prenatal appointments.

  Control of maternal hyperglycemia and maternal gestational weight gain during pregnancy are the most important preventative measures in avoiding fetal macrosomia. […] The American Association of Clinical Endocrinologists (AACE) and the American Diabetes Association (ADA) recommend screening women for type 2 diabetes if they have given birth to a 9lb. infant, as this is thought to represent impaired glucose tolerance and be a surrogate for undiagnosed GDM. […] Pregnancy affected by macrosomia is correlated with future development of type 2 diabetes. Women who gave birth to an infant larger than 9 lbs. in the absence of GDM should still be counseled on the risk of acquiring type 2 diabetes and offered earlier screening for this condition.

  A new study published in the Journal Reproductive and Developmental Medicine (RDM) has found a strong association between fetal macrosomia (high birth weight) and overweight and obesity in early childhood among the U.S.-born children aged 2-6 years. […] The researchers suggested fetal macrosomia may be a marker of intrauterine overnutrition and metabolic dysregulation, which may predispose children to excess weight gain and obesity later in life. They recommended that prenatal care providers should monitor fetal growth and counsel pregnant women about the potential risks and complications of having a large baby, as well as the importance of healthy lifestyle behaviors for themselves and their children. […] Preventing in-utero over-nutrition and weight gain during pregnancy could be a promising strategy to break the vicious transgenerational cycle of obesity crisis and mitigate the risks towards the subsequent generations, particularly among the population of colors.

  https://www.babycenter.com/pregnancy/your-body/macrosomia_1152319

  Macrosomia means „large body” and is used to describe a newborn who’s much larger than average. (The average newborn weighs about 7 pounds.) […] Macrosomic babies are more likely to have a difficult delivery. But the risk of complications is significantly greater when a baby is born weighing more than 9 pounds, 15 ounces. […] With a big baby, you have a greater chance of a difficult vaginal delivery. You may also have an increased risk of preterm birth, perineal tearing, and blood loss. […] A large baby also means you’re more likely to have an assisted vaginal delivery or a cesarean. […] If your baby is macrosomic, there’s a higher risk for birth injury and some complications. But most of the possible complications usually resolve with no long-term consequences. […] A macrosomic baby is also at higher risk for low blood sugar, lower Apgar score, childhood obesity, metabolic syndrome in childhood, which can increase the risk of heart disease, diabetes, and stroke, and breathing problems immediately after birth. […] If you had a perineal tear or an episiotomy, be sure to follow your provider’s instructions for perineal care, and watch for signs of infection. […] If you have diabetes or develop gestational diabetes, stick to your provider’s recommendations to control your blood sugar.
