Why do fetuses have birthmarks on their faces?

Many people have birthmarks on their bodies and think these are nothing. But if this birthmark grows on the face, I am afraid that both men and women will want to curse people in their hearts. After all, this is a world where faces are judged. If you live in fear, you may be despised or bullied by others, which may cast an indelible shadow on your soul. So, why are there birthmarks on the face of the fetus? Why are there birthmarks on the face of the fetus?

Birthmarks are abnormal proliferations of skin tissue during development, and abnormalities in shape and color appear on the skin surface. Birthmarks are very common in newborns and are usually discovered after birth. In some cases, birthmarks in newborns only develop a few months after birth.

Birthmarks can usually be divided into pigmented and vascular types. Common pigmented types include nevus of Ohta, congenital nevus, café-au-lait spots, etc.; vascular types include port-wine nevus, strawberry hemangioma, etc. Most birthmarks only affect the appearance, but a small number of birthmarks are combined with abnormalities of body organs and may lead to pathological changes, and should be actively treated.

Every parent wants their baby to be healthy and beautiful in appearance. They don’t want their baby to be born with any birthmarks. However, the birthmark incidence rate in newborn babies is about 10%. How are birthmarks formed? What? There are mainly four factors:

1. Environmental pollution. When the human body is stimulated by external pollutants, it will manifest itself in different ways, and birthmarks are one of them.

2. Living environment. Due to certain adverse problems in personal lifestyle, such as long-term irregular eating, irregular personal life and uncontrolled overeating, etc., it is possible that certain conditions may aggravate the body, thus forming birthmarks.

3. Genetic factors. Some biologists believe that chromosomal mutations during human evolution are then genetically reflected on human skin, forming birthmarks.

4. Malnutrition. Due to the serious deficiency of zinc, copper, calcium, magnesium and other trace elements as well as phenylalanine and tyrosine in human serum, the biochemical process of pigment synthesis is affected, resulting in an abnormal increase in pigment cells, which gradually spreads to the epidermis through nerve transmission. , forming a birthmark. Can fetal birthmarks be seen in 4D?

Birthmarks cannot be seen in 4D color Doppler ultrasound. Four-dimensional color ultrasound is a kind of volume imaging, which is different from the color photosensitive imaging of general photography. It can be simply understood as imaging the fetus and amniotic fluid together, and then removing the amniotic fluid part. However, the placenta, umbilical cord, uterine wall, etc. cannot be removed during the imaging process. It fell off, so it sometimes appears as a different shade in the picture, but it is not actually a structure on the fetus.

Four-dimensional color ultrasound can observe the growth and development of intrauterine fetuses from multiple directions and angles, providing accurate scientific basis for early diagnosis of fetal congenital surface malformations and congenital heart diseases. Four-dimensional color ultrasound can also examine the fetal body surface, such as cleft lip, spina bifida, brain, kidney, heart, skeletal dysplasia, etc., so as to provide early treatment. Four-dimensional color ultrasound allows doctors to observe the dynamic movement of the internal organs of the human body in real time. But birthmarks cannot be seen on four-dimensional color Doppler ultrasound.

Birthmarks cannot be seen on four-dimensional color ultrasound. Birthmarks are abnormal proliferations of skin tissue during development, and abnormalities in shape and color appear on the skin surface.

Four-dimensional color ultrasound can only detect whether the baby has deformities, such as cleft lip and palate, limb development malformations, brain overflow, spina bifida, abdominal wall clefts and other congenital malformations. The birthmark cannot be seen.

Birthmarks cannot be seen in four-dimensional color Doppler ultrasound. Four-dimensional color Doppler ultrasound examination mainly checks the development of the fetus. This does not check the marks.
