Is the size of the pregnant mother’s stomach proportional to the weight of the fetus? not always!

Pregnant women will pay attention to their stomach changes every day. Will also unconsciously compare with other pregnant women’s belly size. Does this comparison make sense? Is pregnant belly big, fetal big? not always! I’ve been pregnant for more than five months now, but my stomach is not so obvious. It’s just that I grow a circle after every meal, but it shrinks back the next day. My friend is only four months pregnant, his stomach has been a big circle, is obviously a pregnant woman. < / P > < p > my stomach popped out in 4 months. The size of the fetus has nothing to do with the size of the stomach. Some people have big stomachs, and their children are not big. As long as the baby develops normally. < / P > < p > it has nothing to do with whether the baby is good or not. The anterior wall of the uterus is more obvious and the posterior wall is not. When I was 4 months old, my stomach was flat. I grew up in more than 5 months. < / P > < p > 5 months; but now it’s 5.5 months; it’s not obvious. My husband’s male colleague said that my stomach was not as big as his beer belly. < / P > < p > Yes, it’s not that the bigger the stomach, the bigger the fetus. Generally speaking, the relationship between the size of pregnant women’s stomach and amniotic fluid, fat accumulation and pelvis is relatively close. And every pregnant woman is different. < / P > < p > mothers to be who are pregnant for the first time usually begin to notice their tummy bulge at 12-16 weeks of gestation. Many mothers begin to show their first baby between 12 and 18 weeks of pregnancy, while those with the second and later babies vary between 6 and 18 weeks of pregnancy. < / P > < p > expectant mothers who are pregnant for the first time usually have a later bulge because their muscles are not stretched by the last pregnancy. Mothers to be who are tall or long may have smaller stomachs. They have more room to hold their babies vertically. In addition, the baby’s position in the womb will also affect the appearance of the stomach. < / P > < p > doctors or midwives will use a number of measurements to determine whether the baby is developing normally. In the early stages of pregnancy, doctors will give expectant mothers a pelvic examination to assess the size of the uterus, or B-ultrasound to see the size of the baby. < / P > < p > at about 20 weeks of pregnancy, doctors will estimate the size, growth rate and fetal position of the baby based on the height of the mother to be. Third, the small size of fetus detected by B-ultrasound is sometimes due to human factors. Some doctors are used to calculating the length according to * inside, which may reduce the size of the fetus. Fourth, excluding the above factors, if the gestational period increases, but the fundus rises slowly, which is obviously less than the gestational month, there may be intrauterine growth retardation and dysplasia. At this time, we should strengthen nutrition and take in high-quality protein, such as fish and shrimp, which are rich in protein. Some mothers are picky about food, which can also lead to fetal dysplasia. For the sake of fetal health, gestational food should emphasize diversification. Grains, vegetables and fruits, fish, poultry and eggs should be eaten. They can be properly combined and eaten. Do not overeat. < p > < p > the health of pregnant mothers has the greatest impact on fetal babies. Malnutrition, partial food intake, hyperemesis during pregnancy, insufficient intake of protein and vitamins, smoking, drug abuse and high mental stress will all have adverse effects on the development of fetal babies. Intrauterine infection, exposure to radiation or toxic substances, and uterine malformation during pregnancy can easily lead to fetal baby growth restriction. If pregnant women suffer from hypertension, anemia, dissatisfaction with diabetes control, heart disease, intrahepatic cholestasis and other complications, the placental blood perfusion will be reduced, which will affect the physical development of the baby. Of course, mother’s short stature and other congenital factors can also affect the baby’s birth weight. < p > < p > for example, chromosomal abnormalities, intrauterine virus infection and multiple pregnancy often lead to low birth weight and growth restriction; abnormal umbilical cord development, such as single umbilical artery, umbilical cord torsion, knotting, too long and too thin, can affect the blood flow of fetal baby placenta and cause fetal baby growth restriction. Placental dysplasia, placental vascular infarction, calcification, thrombosis and so on, directly affect the nutrient supply of fetal baby, resulting in fetal baby chronic hypoxia and growth restriction. Insulin growth factor, growth hormone and other substances regulating the growth and development of fetal baby decreased in umbilical cord blood, which may affect the endocrine and metabolic function of fetal baby, and also lead to fetal baby growth retardation.

experts remind us to actively prevent and treat pregnancy complications, so as to reduce incidence rate. The causes of intrauterine fetal growth retardation are complex and various, including maternal, fetal baby, placenta and umbilical cord. The key to prevent intrauterine growth retardation is to pay attention to prenatal examination, timely detection and treatment, formulate targeted measures, and strengthen the prevention and treatment of pregnancy complications and complications. < / P > < p > clinical diagnosis: it is mainly used for screening according to the changes of uterine height, abdominal circumference and weight of pregnant mothers. If the uterine height and abdominal circumference of the pregnant mother are less than 10% of the corresponding gestational age for three consecutive weeks, or the weight growth is slow or stagnant, it can be considered as fetal baby growth restriction, and ultrasound examination should be carried out. < p > < p > B ultrasound detection: measuring the baby’s body diameter line, placenta and amniotic fluid in each gestational week, can confirm whether there is a fetus or not, baby growth restriction. Pregnant mothers should pay attention to the following indicators: head circumference / abdominal circumference ratio, biparietal diameter, femur length. For example, the biparietal diameter increased by 3.6 mm in the first trimester, 2.4 mm in the second trimester, and 2.0 mm in the third trimester. If the biparietal diameter of the baby can not be measured for several consecutive weeks, the growth restriction of the baby should be considered. Ultrasound found that the amount of amniotic fluid is small, placental blood perfusion is reduced, placental aging, we should also pay attention to whether there is fetal baby growth restriction. < p > < p > using color Doppler ultrasound: observe and measure the maximum systolic blood flow velocity and the minimum diastolic blood flow velocity of umbilical artery, the ratio of the two, i.e. s / D value, is also of great significance for the diagnosis of fetal growth restriction. The S / D value is usually measured from the 24th week of gestation. When the S / D ratio in the third trimester is more than 3.0, the possibility of fetal baby growth retardation is very high.

experts warn that fetal baby growth restriction not only endangers the life of baby babies, but also has a serious impact on the growth and development of baby babies after birth. The growth of babies is manifested by their height, physical ability and mental retardation. The incidence rate of cardiovascular system, nervous system and metabolic diseases after adulthood will also be higher than other normal peers. Many diseases are diagnosed only after birth, which delays the treatment time. Therefore, the discovery of intrauterine growth retardation during pregnancy is the key to reduce the perinatal mortality. < p > < p > once intrauterine growth retardation occurs, especially in the late pregnancy, the treatment effect is not good, so we can actively prevent the causes of intrauterine growth retardation, and get twice the result with half the effort. < / P > < p > ● actively prevent and treat pregnancy complications and various chronic diseases, such as anemia, thyroid disease, diabetes, etc. at present, there is no effective prevention method for some pregnancy complications, such as pregnancy induced hypertension, cholestasis, etc., so active monitoring, early detection and intervention should be carried out during pregnancy. < / P > < p > ● scientific diet, adhere to healthy living habits. Food should be diversified, never partial food, advocate eating all kinds of seasonal fresh vegetables, fruits, protein and sugar rich food, less fat; timely treatment of hyperemesis gravidarum, no smoking, drinking, pay attention to supplement vitamins, trace elements, etc. < / P > < p > experts remind: under no special circumstances, it is not necessary to turn to pharmaceutical supplements; when necessary, whether using supplements or medical drugs, they must be taken under the guidance of full-time obstetrics and gynecology doctors and pediatricians. Do not use drugs indiscriminately. Under the guidance of doctors, use some vitamins, trace elements, amino acids, etc.; or improve fetal umbilical artery circulation, increase fetal baby blood supply, and carry out corresponding treatment. If there is no significant improvement in treatment or there are serious problems in the diagnosis, serious consideration is needed. CUISINE&HEALTH
