What is head-to-hip diameter?

Before getting pregnant, you need to do relevant pregnancy preparation checkups. After getting pregnant, you also need to go to the hospital for regular checkups to see how the baby is doing. When the baby is born, you also need to do some examinations. No one wants to give birth to an unhealthy child. So what does the baby's head-brachial diameter refer to?

The so-called baby's head-brachial diameter actually refers to the distance from the baby's head to the baby's buttocks. In fact, the brachiocephalic diameter still has certain functions. It is important to understand that all data has its purpose, and the value of the brachiocephalic diameter is related to the child's physical and mental health, or whether the child's growth and development is within the normal range.

Some people want to know whether they are pregnant with a boy or a girl when they are pregnant, so they will also use the data of the head arm diameter to test it. Although the number of weeks of pregnancy and the date of delivery can be calculated based on the value of the brachiocephalic diameter, it is not possible to determine whether the fetus is a boy or a girl based on this data alone.

Generally, after ten weeks of pregnancy, the baby's brachiocephalic diameter will be higher. Now, after ten weeks of pregnancy, the baby's brachiocephalic diameter is about 31mm. After seeing the doctor for examination, it was found that the brachiocephalic diameter is not 31mm, but slightly lower. Mothers do not need to worry too much. Just supplement more nutritious foods and drink more bone soup. The next examination will be normal.

What is the fetal head brachial diameter? Is it a boy?

The brachiocephalic diameter refers to the distance from the top of the fetus's skull to the edge of the buttocks. It is usually measured around 7-12 weeks of pregnancy. The gestational age can be calculated based on this, but the gender of the fetus cannot be determined. Generally, the gender of the fetus can be determined by B-ultrasound around 5 months of pregnancy.

How to know the sex of the fetus?

1. Distinguish from the appearance of the pregnant woman's abdomen. If a pregnant woman's belly is pointed and protruding, she will be pregnant with a boy. If her belly is snow-white and butt-shaped, she will be pregnant with a girl.

2. Determine whether the pregnant woman is having a boy or a girl by observing the change in her taste. Many people think that if the taste of a pregnant woman is different from that of the previous pregnancy, the chances of having a boy or girl will also change. If the taste is the same as before, then the gender is also the same, otherwise it is the other way around.

3. Determine whether it is a boy or a girl by the speed of the fetal heartbeat. It is generally believed that if the fetal heartbeat is strong and fast, the possibility of having a boy is very high; on the contrary, the possibility of having a girl (one of the more common symptom methods of guessing a boy or a girl) is higher.

4. Observe the changes in the pregnant woman’s skin and appearance. If a pregnant woman's face becomes more and more beautiful, and her skin becomes more and more smooth, she may be pregnant with a girl. On the contrary, if her face becomes uglier, her skin becomes less and less smooth, or even her face is covered with acne and other symptoms, she may be pregnant with a boy. This is a more common way to conceive a boy or a girl.

5. Expectant mothers who are pregnant with boys like to eat their favorite foods. The average protein intake of pregnant women carrying boys was 8% higher than that of pregnant women carrying girls, the carbohydrate intake was 9% higher, the animal fat intake was 11% higher, and the plant fat intake was 15% higher. Pregnant women with male fetuses eat much more food during pregnancy than when they are not pregnant, but they do not have symptoms of eating different or strange foods, but just eat their usual favorite foods.
