Is a large fetal head high IQ, or hydrocephaly?

<>Definition of fetal head size:

The fetus has a large head, which is expressed in medical terms as "double parietal diameter". The double top diameter, also known as BPD, is the width of the widest part of the left and right sides of the head. Through this value, the development of the fetus can be observed, and a preliminary judgment can be made on whether the baby will have a smooth delivery in the future.

Through the double top diameter, it is also possible to determine whether the head and pelvis are symmetrical, that is, whether the size of the fetus's head and the size of the pregnant mother's pelvis match.

If the pregnant woman's pelvis is small and the baby's head is much larger than the pelvis can bear, it is a case of cephalopelvic asymmetry. Or the fetus head is normal, and the pregnant mother's pelvis is small, both of which are not conducive to normal delivery.

In layman's terms, whether a pregnant mother can give birth smoothly depends on the data of the comparison between the double top diameter of the fetus and the size of the pelvis of the pregnant mother.

Fetal double parietal diameter range at different gestational weeks, and those who meet the standards belong to normal development:

Causes of large biparietal diameter of the fetus:

The reason why the fetus has a large double parietal diameter is generally caused by overnutrition and too good development.

What does a large double top diameter represent?

1.Does it represent fluid in the head?

Is there a correlation between the large double top diameter and the accumulation of water in the head? The answer is no, but water accumulation in the head can also cause the double top diameter to be too large to a certain extent. Hydrocephalus refers to the widening of the lateral ventricles or cysts of the ventricles, and in general, fetal lateral ventricles greater than 10 mm wide indicate the presence of hydrocephalus.

2.Does it represent the fetus being smart?

The answer is "of course not", there is a saying that babies are smart when they have a big head, but the doctor did an experiment, after Einstein's death, the brain was taken out, and there is no difference in weight and volume from ordinary people, so there is no correlation between head size and IQ.

3.Can the fetus weigh it?

The biparietal diameter of the fetus is capable of ** fetal weight, which can be followed by the following formula:

Fetal weight Double parietal diameter * double parietal diameter * double parietal diameter + abdominal circumference * abdominal circumference * femur length. (Note: All units are centimeters).

In any case, if the double parietal diameter is too large and exceeds the size of the mother's pelvis, it is not conducive to natural childbirth, and it is easy to cause dystocia, and even the risk of "giant baby". Therefore, how to prevent this situation has become a top priority.

How to effectively prevent the double top diameter from being too large?

First of all, pregnant mothers should rule out the triggers of diseases such as hydrocephaly. For the case of excessive nutrition caused by excessive double top diameter, pregnant mothers should pay attention to increasing the amount of exercise, taking more walks, basking in the sun, and doing yoga for pregnant women. In particular, it is necessary to eat a balanced diet, avoid excessive sugar intake, and eat less sweet, high-quality fruits and sweets.

Hydrocephalus, because a large head has nothing to do with high IQ, it may be caused by hydrocephalus, so pregnant mothers should pay more attention.

If the fetus's head is particularly large, it is recommended to go to the hospital to check whether it is hydrocephalus.

Fetal head size has nothing to do with IQ, and it is not necessarily hydrocephaly, it is likely to be the influence of genes.

Fetal head is large, in fact, it is generally caused by hydrocephalus, which is a disease, or should it be treated as soon as possible**.

How can you tell if your baby has hydrocephalus? Hydrocephalus is a serious physiological problem of the fetus during pregnancy, in severe cases, it will lead to abnormal fetal intelligence, and even malformation or death. Maybe the relevant symptoms are not obvious, but if there is any abnormality, it is best to go to the hospital for examination, so that the fetus can grow up healthy and happy.

During pregnancy, ultrasonography can detect a variety of intracerebral developmental abnormalities, including open neural tube development advancement, such as spina bifida, as well as structural abnormalities in the brain, and scattered limbs such as hydrocephalus, schizoid malformation, congenital agenesis of the corpus callosum, and intracranial space-occupying lesions. Congenital hydrocephalus appears to be the most common occurrence on clinical ultrasound because of the many signs of hydrocephalus that can manifest in many intracranial dysplasias. Hydrocephalus is an excessive accumulation of cerebrospinal fluid in the ventricular system, dilation of the lateral ventricular system, increased pressure, and widening of the ventricles on ultrasonography.

In general, a widening of the lateral ventricular triangle of up to a centimeter is considered to be an enlarged ventricle, and the wider it is, the heavier it is. If the triangle is centimeter wide and the choroid plexus occupies more than 50% of the ventricles, it is generally considered normal. If the choroid plexus is shrunk and suspended, hydrocephalus is assumed.

There are many causes of hydrocephalus, in addition to excessive cerebrospinal fluid production, it is also caused by malabsorption or blockage of the aqueduct in the midbrain. Hydrocephalus can occur at any time during pregnancy due to sequelae of certain diseases such as intracranial hemorrhage and infection. Therefore, hydrocephalus may occur in the third trimester of pregnancy, even in patients with normal brain development during pregnancy, so ultrasound during pregnancy is necessary.

In addition, some conditions may be mistaken for hydrocephalus, and an experienced sonographer will make an informed diagnosis based on the comparison of relevant factors, and the mild abnormalities found during pregnancy can be accurately diagnosed by dynamic observation.

Stair climbing is a low-intensity exercise, and climbing stairs regularly is good for the body. Is it good for pregnant women to climb stairs? The answer is good, and the benefits are numerous.

Pregnant women climbing stairs can have the effect of exercise, strengthen the heart function of the expectant mother, and can also move the pelvis, increase appetite and sleep, maintain muscle health, increase the flexibility of the body, and promote the blood circulation of the expectant mother, which is not only conducive to the delivery of nutrients to the fetus, but also helps to discharge the waste produced by the fetus. It can also exercise the thigh and buttock muscles of pregnant women, enhance the physical strength of pregnant women, and play a role in speeding up childbirth and promoting postpartum recovery.

If you have been climbing stairs before, then you can continue during pregnancy, if you have not climbed stairs before and you are out of breath when you climb, then it is recommended that you do not force yourself to climb stairs. Secondly, the stairs must be climbed in moderation, do not climb more than 4 flights of stairs in a day, and only go up the stairs, not down the stairs. To make the pelvic activity and increase elasticity, the most effective is to "squat down", pregnant mothers who can't climb the stairs may wish to do some easy squatting movements in their own homes, and they will also receive good exercise results.

Hydrocephalus is caused by the deformation or obstruction of the nozzle or hole between the parts of the ventricular system due to abnormal development or viral infection, which obstructs the circulation of cerebrospinal fluid, so that the cerebrospinal fluid collects in the whole ventricle or a certain part of the ventricle.

Children with hydrocephalus have a large head, wide cranial sutures, a chimney that never closes, a relatively small face, and a compression of the white eyeballs. There are different degrees of brain retardation and mental retardation due to different degrees of compression of brain tissue. Due to high intracranial pressure, sick children are prone to vomiting and headache, which affects appetite and development.

Severe hydrocephalus often dies of dystocia due to a large skull, and the light one can put cerebrospinal fluid to lower cranial pressure, but it is not easy to completely **, and the sequelae, mental retardation, etc., often die young.

Prevention of hydrocephalus is very important, and pregnant women should strengthen the prevention and treatment of viral infections in the early stages of pregnancy.
