Examination of fetal growth disorders A percentage of babies are born at both ends of the fetal growth spectrum. At one end of this spectrum are macrosomic babies (weighing more than 4 kg) and at the other end of the spectrum are babies with low birth weight (weighing less than 2500 grams). Mortality in this group is 1% (compared to 0.2% in natural childbirth). newborn weight) and is associated with early and temporary complications such as hypoglycemia, hypothermia, meconium aspiration and late and permanent complications such as learning disorders. Premature delivery is relatively common in these patients. Estimating the weight of the fetus is not very accurate and sensitive, and in fact, the size of the fetus alone is not very valuable in predicting the size of the fetus, and it is very important considering the size of the fetus. The dimensions of the mother's pelvis... the fetus** According to gynecologists, the determining factors of fetal growth are: - Food supply by the mother: for example, increasing and decreasing the access of the fetus to maternal glucose affects the growth of the fetus... too much blood sugar causes macrosomia, while the reduction of glucose is related to the restriction of the growth of the fetus... - Nutrient transfer by the placenta. - Fetal growth potential that is influenced by the fetal genome... The exact cellular and molecular mechanisms that cause normal fetal growth are unknown... In the early stages of fetal life, the fetal genome is the main determinant of growth, but in the later stages of pregnancy, environmental, nutritional and hormonal factors become important. In terms of neural development, it is affected by both the environment before birth and the environment after birth... Babies who are born in families with a high socio-economic status show fewer developmental problems compared to babies born in poor families... For a detailed examination of these problems, the patient needs a careful examination by a gynecologist.. Tehran is as follows: Ovarian cyst Cesarean delivery Infertility treatment
