What is the cause of small head and why is small head

The first reason for the small head of the fetus is genetics, the heads of the parents are not large, and everyone's head shape is different, so it is likely that the head will be small. The second reason is due to fetal growth retardation and nutritional deficiencies. Because the nutrients consumed by the fetus are not enough to promote the development of the body, the growth of the body will be smaller than that of the normal fetus.

Factors affecting the fetus.

1. Expectant mothers smoke and drink alcohol that affects the growth of the fetus.

Some expectant mothers also smoke and drink alcohol during pregnancy, and the harm of tobacco and alcohol will naturally be absorbed by the fetus, and the toxins will affect the growth of the fetus and even cause fetal malformations. Therefore, tobacco and alcohol are important factors in the development of low birth weight fetuses.

2. Uterine placenta abnormality leads to small fetus.

Uteroplacental abnormalities in expectant mothers can reduce the flow of blood in the placenta and uterus, resulting in insufficient blood supply to the fetus, which will affect the development of the fetus and endanger the life of the fetus in severe cases. Therefore, if a pregnant woman is found to have such a condition, she should go to the hospital immediately**.

It doesn't matter if the fetus is one to two weeks smaller, it's normal. Generally speaking, the doctor will recommend that you pay attention to rest, do not overwork, and usually eat more nutritious food to promote the growth and development of the fetus, but pay attention to the weight of the pregnant mother not to increase significantly in a short period of time, which is not conducive to smooth delivery during childbirth.

The difference between microcephaly and microcephaly.

Microcephaly can be divided into true microcephaly and relative microcephaly (also called pseudomicrocephaly). Some parents will simply think that microcephaly is a small head, so as to make wrong judgments, but in fact, microcephaly is not just as simple as a small head.

First, what is a small head? At birth, the head circumference of a normal newborn is about 34 cm, which increases by about 10 cm within the first year of birth, about cm in the second year, and 53 cm or more by the age of 18. In patients with microcephaly, the head circumference is usually no more than 43 cm and may be less than 25 cm.

The frontal lobe of the child is also significantly reduced, and parents can measure the frontal lobe of the baby at home, which is the distance between the posterior wall of the anterior horn of the lateral ventricle and the medial surface of the forehead skull. On the median sagittal plane of the face, the forehead is markedly retracted.

Secondly, babies with small heads only have a relatively small head circumference, but their facial features are normal. In patients with microcephaly, not only the head circumference is small, but also the shape of the child's head is mostly small and pointed at the top of the head, the forehead is narrow, the cranial vault is small, the occipital part is flat, the face and ears look relatively large, the fontanelle and bone suture are closed prematurely, and there may be interosseous crests.

In addition, it is more important to judge the development of the baby's language ability and behavioral ability, as well as whether the intellectual development is very different from that of peers. Because if the baby's head circumference is only small, his intellectual development will not be affected. If your baby is slow to react and you clearly feel that your baby's mental development is stagnant or stunted, you should pay special attention to your child's development.

Hello, when a normal child is about one year old, it looks like the head will be bigger, especially when the head is shaved and it will be bigger, because this is the process of development, but it can't be too big, you said that the child's head is already disproportionate to the body, this may be your subjective feeling, as for whether it is normal, to be examined and analyzed. Generally pathological, common in skull dysplasia, hydrocephalus, increased intracranial pressure caused by various reasons, etc., if the child has a history of premature birth or birth abnormality, then the possibility of a large head is abnormal.

Guidance: It is recommended to do a head MRI to exclude cases such as cerebral dysplasia hydrocephalus, in addition, if the child's head is abnormal, then there will be some manifestations such as movement disorders, developmental delays, etc. If your child is developing normally but feels that his head is a little bigger, then it is likely that there is a personal sensory problem.

Hello! First of all, this kind of small head still needs to consider both genetic and acquired development factors. If you have a small head, but there is no abnormality in intelligence or other aspects, and there is no discomfort such as headache and dizziness, I don't think there is a big problem.

Analysis:

To be precise, your symptoms are not a disease, and the head is relatively small, which can only mean that you are born with a small head.

Guidance: According to your description, the symptoms of your relatively small head are your natural traits, not diseases, which is not a **, just like some people have larger hands and some people have smaller hands, and they cannot be regarded as diseases**. In your case, it is recommended that you keep your hairstyle mature, cut your hair short, never cover your face, or tie your hair up to make your face look bigger.

The head is just a little smaller. It's not ugly, I never dared to cut my hair short when I was studying. But it's not just a matter of time, in fact, this is mainly a matter of mentality.

When you see an uneven look that is uglier than you and a head smaller than yours in the future, you will be relieved. Also, in the future, when you get older, you will experience more things, and your face will show a sense of cangsang, then it will be a taste again.

1.Chromosomal and genetic abnormalities.

Chromosomal abnormalities such as Down syndrome can cause microcephaly, as can microcephaly related genes such as MCPH1 defects.

2.Maternal infection during pregnancy.

If the mother suffers from toxoplasmosis during pregnancy, or is infected with Zika virus, cytomegalovirus, rubella virus, herpes virus, syphilis, HIV, etc., it can be transmitted to the fetus, causing abnormal fetal brain development and microcephaly after birth.

3.Severe maternal malnutrition during pregnancy.

If the mother does not receive enough food and nutrients during pregnancy, it will also cause malnutrition in the fetus, leading to the occurrence of microcephaly.
