During pregnancy, the weight of the fetus is a matter of great concern to pregnant mothers. Some pregnant mothers often estimate the fetal weight through their abdomen, but sometimes the change of abdomen is not the change of fetal weight. It may be that there is more fat in the abdomen, there is no fetus in the long meat, and the amniotic fluid in the uterus increases, which leads to great changes in the abdomen, which does not mean that the fetus must develop well.

28 ~ 36 weeks is the best stage of development, and pregnant mothers must always pay attention. By the 36th week, the average fetal weight can reach 2500g, the height can reach 48cm, and the head diameter is about 90mm.

The difference between 5-6-7-8 kg fetus First of all, the fetus is 5 kg.

If the fetal weight is less than 5 kg, it is overweight and needs to be kept warm. What are the factors that cause the fetus to weigh 5 kg?

1, if the fetus is less than 5 kg at birth, it means that the fetus is stunted during pregnancy, and there are many factors leading to fetal stunting. For example, during pregnancy, the nutrition intake of pregnant mothers is not comprehensive enough, and pregnant mothers are not pregnant.

2. During pregnancy, the fetus suffers from hypoxia, intrauterine infection and other factors, resulting in slow fetal development, so the fetal development is relatively poor. Did not reach 5 kg at birth.

3, placental aging will also affect the development of the fetus. If the placenta is aging during pregnancy, the ability to support and provide nutrition to the fetus is insufficient, not only will it develop slowly during pregnancy, but it will also face hypoxia.

Second, the fetus weighs 8 kilograms.

A fetus weighing more than 8 kg is a macrosomia, which does not mean that the bigger it grows, the healthier it is, because during pregnancy, the pregnant mother suffers from gestational diabetes and her blood sugar concentration is relatively high, so the fetus is more prone to macrosomia.

Many pregnant mothers are trying their best to take nutrition during pregnancy, but they don't pay attention to the digestive ability of the fetus. During pregnancy, the digestive ability is poor, not as strong as postpartum. If pregnant mothers eat too much nutrition, nutrition will accumulate, pregnant mothers will be obese, and fetuses will be more likely to be obese.

Third, the fetus weighs 6-7 kg.

It is ideal to weigh 6~7 kg at birth, and it is a good signal to develop well during pregnancy. However, it is necessary to check the development of various organs of the fetus at birth to see if there is any abnormality.

The fetal weight is 6~7 kg, indicating that the pregnant mother has sufficient activity and comprehensive nutrition during pregnancy. Pregnant mothers pay more attention to their own mentality, get enough sleep and the fetus will be healthier.

During pregnancy, pregnant mothers must pay attention to their diet, activities and sleep, because these factors will affect the development of the fetus. Fetal weight is not only related to heredity, but also to the development during pregnancy.

In the process of pregnancy, you must pay attention to check your body on time. Prenatal examination can find the development of the fetus in time and the height and weight of the head. These are all known through prenatal examination. Pregnant mothers can't directly obtain fetal information through physical changes.
