The rising prevalence of newborns with excessive birth weight has emerged as a significant challenge in contemporary perinatal care. Pathologically accelerated fetal development is associated not only with immediate obstetric complications but also with long-term health consequences, including an elevated risk of insulin resistance, lipid metabolism disorders, and obesity later in life. Ensuring optimal fetal development conditions necessitates a comprehensive approach, encompassing meticulous preconception management of prediabetic and hypertensive states in the mother, alongside personalized supplementation and lifestyle modifications throughout pregnancy.

The fetal macrosomy is determined by the abbreviation LGA (Large fo gestational age) and is found when a newborn's birth body mass exceeds 4000 5000 g, regardless of the time of pregnancy or when the birth mass is greater than 90%. Percentage for a specific gestational aged population. Research indicates that a better definition is to diagnose macrosomia using the body length and birth mass values of the infant relative to the centreline grids for age, weight, race and sex.
The matrix of the fetus is the cause
Causes of fetal macrosomes: maternal obesity, type 1 or type 2 diabetes and gestational diabetes, gestational hypertension, preterm birth, postpartum delivery, pregnancy after 45 years, pre-natal birth, multiple birth, ethnicity, parental growth and body mass, male and female fetal sex, maternal and fetal carcinoma, and in particular fetal diabetic retention, prenatal hypertension and also gestational blood pressure, post-partum childbirth, postnatal pregnancy, polycystic ovarian syndrome, multiple pregnancy, racial origin, progenitor' s body weight, pregnancy-to-be-pregnancy obesity and obesity prevalence, which are considered by doctors to be the most prevalent risk factors for pregnant women, especially those who are overweight or obese.
Macrostomy of the fetus Symptoms
The birth mass of the fetus with a macroma exceeds 40004500 g and the appearance of the disproportion between the size of the uterus in relation to the smaller one. For the first option, the ultrasound is used, whereas after birth the newborn's size is compared to those of the sixty centimetres corresponding to the gestational age and sex of the baby.

According to the American College of Obstetricians and Gynecologists, a cesarean section should be performed when the best solution is not clearly distinguished. In studies, we can find the following: birth induction, i.e. artificially inducing birth contractions by giving the mother oxytocin, which results in premature birth; planned caesarean sections. According to recommendations from the American college of obstetrics and gynecology, caesarea should be carried out when it is more than 5,000 g in healthy mothers, 4,500 g in well-to-do mothers.
