What should I do if the double top diameter is small, and how to make up for the small double top di

Don't listen to the doctor's alarmism, when I was 37 weeks pregnant, B ultrasound showed that the baby had a double top diameter, and the femoral doctor also said the same, and said that if it really doesn't work, don't ask for it, let me induce labor!! I was about to cry to death, and then my husband found a very famous obstetrics director to do B ultrasound again, he said that the child's head is slightly round, and the natural double top diameter will be less than the normal value, this is because my child's fetal position is not correct (breech), the reason why my organs are squeezed, and analyzed the amniotic fluid and placenta since pregnancy, he thinks there will be no problem at all, and the position of the baby when doing b ultrasound will also affect the data of b ultrasound, which are not 100% accurate in the number of concepts, let me be bold in life, It's just recommended that it is best to give birth to a baby by caesarean section in advance, and then I did the surgery at 39 weeks, and now my baby is a little more than five months old, normal, cute and lively, anywhere is well developed, large movements can meet the requirements of development, head circumference is also completely within the normal value, and the development is good, every time I go to the child care score is an excellent baby! So you must not let your wife have ideological pressure, analyze other situations, like amniotic fluid, if the malformed amniotic fluid will be abnormal, either more or less, and then see if your wife has been pregnant (especially in the first trimester) whether there is a bacterial infection, whether there is contact with toxic things and radiation, whether there is pregnancy hypertension in the third trimester, etc., if these are not, this means that your wife and I are in the same situation, then you have no need to worry, a good mood is the key to the healthy growth of the baby, don't be afraid, I'm sure the baby and mom will be fine, bless them!

Hello, the results of the examination are about 21 weeks in size, and the normal gestational week is 22 weeks smaller, but it is not too small, generally speaking, pregnancy and normal menstrual cycles are large and small within a week are normal Everyone has a different diet, nutrition is different, and the speed of fetal development will be different, it is recommended to go with the flow, eat more nutritious food, and you can also eat some pregnant women calcium tablets pregnant women calcium milk powder.

This situation varies from person to person and is also directly related to nutritional status, and it is not excluded that irregular menstruation, inaccurate gestational age or errors in ultrasound measurement are not ruled out. If there is no obvious developmental abnormality, there is no need to be overly concerned. Pay attention to the rules of life and diet, pay attention to strengthening nutrition, eat more high-protein foods, and do regular physical examinations.

The term "double parietal diameter" will appear in pregnancy check-ups, and some careful mothers may find that the size of the fetus is smaller than the normal range after comparison. How to make up for the small double top diameter？What is the significance of checking the double top diameter?

Let's take a look at the knowledge of double top diameter.

The double parietal diameter is only slightly smaller than normal and may be related to nutritional deficiencies or slower growth. Of course, it is more likely that the gestational age calculated by the last menstrual period does not match the fetus, that is, the fetus gestational sac implants late (the actual gestational age of the fetus is less than the estimated gestational age), so this problem is not big. It is recommended that you strengthen your nutrition, pay attention to rest, exercise appropriately, and review the three-dimensional color ultrasound after half a month.

Generally, there is no problem with a small double top diameter, it is recommended to increase nutrition, pay attention to small and frequent meals, eat more foods containing high protein and high vitamins, eat more vegetables and fruits, and pay attention to regular pregnancy tests.

Double parietal diameter, also known as BPD, double parietal diameter of the fetal head. It refers to the length of the widest part between the left and right sides of the fetal head, also known as the "large transverse diameter of the head". Doctors often use it to observe the child's development and determine whether there can be a cephalopelvic disproportion and a smooth delivery.

At term, the diameter of the fetal should be centimeters or more. According to the general rule, after 5 months of pregnancy, it basically corresponds to the month of pregnancy, that is, BPD is about centimeters at 28 weeks (7 months) of pregnancy, about centimeters at 32 weeks (8 months) of pregnancy, and so on. After 8 months of pregnancy, it is normal to have an average weekly growth of about centimeters.

When the expected date of delivery cannot be determined by CRL in the initial stage, BPD is often used**; After the middle term, this data is often also measured when determining the weight of the fetus.

The weight of the fetus is calculated by using the double parietal diameter examination, and the formula is: fetal weight = double parietal diameter * 900-5200 (grams).

Fetal development standards are one of the most important concerns of many expectant mothers in their daily lives. Expectant mothers feel special happiness every day as the fetus grows up day by day. At the same time, I am particularly worried about the development of the fetus.

So, what should I do if the fetus has a small biparietal diameter? Does it matter if the fetal double parietal diameter is small?

Does it matter if the fetal double parietal diameter is small Fetal double parietal diameter is also directly related to nutritional status, the double parietal diameter is small, which does not rule out the usual irregular menstruation, and the current gestational age is inaccurate or caused by the error in the measurement of B ultrasound. If there are no obvious developmental abnormalities, there is no need to be overly concerned. It is recommended to pay attention to the rules of life and diet, pay attention to strengthening nutrition, eat more high-protein foods, and do regular physical examinations.

Does it matter if the fetal double parietal diameter is small?

If the fetal biparietal diameter is small, there is no problem if it is only a little off. Some deviations, it should be the problem that your nutrition can't keep up, malnutrition, is the diet not very good, you must ensure the nutrition of the diet.

At 12 weeks of gestation, the diameter of the fetus is centimeter, which is a standard value. The following are the standard values for the double parietal diameter of the fetus during each pregnancy:

The mean of the 13-week fetal biparietal diameter is 14-week fetal biparietal diameter.

The mean of the 15-week fetal biparietal diameter is 16 weeks.

The mean of the 17-week fetal biparietal diameter is The mean of the 18-week fetal biparietal diameter is.

The mean of the 19-week fetal biparietal diameter is 20 weeks.

The mean of the 21-week fetal biparietal diameter is The mean of the 22-week fetal biparietal diameter is.

The mean of the 23-week fetal biparietal diameter is the mean of the 24-week fetal biparietal diameter.

The mean of the 25-week fetal biparietal diameter is The mean of the 26-week fetal biparietal diameter is.

The mean of the 27-week fetal biparietal diameter is The mean of the 28-week fetal biparietal diameter is.

The mean of the 29-week fetal biparietal diameter is 30 weeks.

The mean of the 31-week fetal biparietal diameter is 32 weeks.

The mean of the 33-week fetal biparietal diameter is The mean of the 34-week fetal biparietal diameter is.

The mean of the 35-week fetal biparietal diameter is The mean of the 36-week fetal biparietal diameter is.

Is it scientific to look at male and female femur length Double parietal femur length is unscientific to look at men and women, and it can only be said that double parietal diameter and femur length can estimate the weight and size of the fetus. The length of the femur refers to the length of the fetal thigh bone, and the length of the femur can be estimated according to the double parietal diameter, such as the double parietal diameter is centimeters, and the femur length diameter is centimeters. If the femur diameter and the double parietal diameter add up to 17 cm, the baby will be very large.

Estimating fetal weight method 1:

Formula: Fetal weight = double parietal diameter * 900-5200 (grams).

Estimating fetal weight method 2:

Head circumference HC, abdominal circumference AC, femoral long FL, fetal leg subcutaneous fat thickness FTH

Formula: Fetal Weight Estimate =

When a pregnant mother goes for a preconception check-up, she will see a numerical data called a double top diameter from the report, what does this double top diameter represent? After comparison, pregnant mothers may find that the double top diameter seems to be too large, resulting inThe reason why the double top diameter is too largeAnd what is it? Could it be an abnormality in fetal development?

The fetal double parietal diameter value is large, it may be that the fetal grinding mountain itself has sufficient absorption of nutrients, so it leads to good physical development, and the natural double parietal diameter will be a little large, but this does not mean that the fetus itself has any problems, but it is possible that when it comes to delivery, if the value of the double parietal diameter is about 10mm, it will cause some obstacles to normal normal delivery. Pregnant mothers generally don't need to worry too much.

Judging the size of a child's development by double top diameter is a reference data. During childbirth, the maximum diameter of the fetus's head through the birth canal is the double parietal diameter, and the smallest diameter of the birth canal for the fetus to pass through is the pelvic exit transverse diameter, so if the double parietal diameter is larger than the pelvic outlet transverse diameter, whether the child can give birth blindly and naturally is a question. The final choice also depends on the woman's pelvis and the size of the child at term.

The double parietal diameter, also known as BPD, is the distance between the two parietal carinae of the fetal head, which is simply the length of the widest part between the left and right sides of the fetal head. Doctors often use it to observe the child's development and determine whether there will be a disproportionate head and pelvis, and whether the delivery can be successful. Before 31 weeks of gestation, the average weekly growth is 3mm, 31-36 weeks of gestation, the average weekly growth is 1mm, and after 36 weeks of gestation, the average weekly growth is 1mm.

At term, this value should be at or above the rate.
