Symptoms of chromosomal abnormalities in women

Women have a total of 23 pairs of chromosomes, and each pair of chromosomes is identical, while men have 22 pairs of chromosomes that are identical, with only the sex chromosomes being different. Chromosomes are the codes of our human genes. Chromosomes can preserve the corresponding images of both parents. At the same time, many congenital diseases are caused by chromosomal abnormalities. Therefore, when a woman has chromosomal abnormalities, she should be checked for congenital diseases.

Symptoms of chromosomal abnormalities in girls

1. So far, the medical community has not reached a very definite conclusion on this issue. However, most scholars believe that chromosomal translocation is related to endocrine disorders, especially in women of older childbearing age, which can easily lead to chromosomal translocation in the eggs.

2. In addition, drug abuse, air pollution, food pollution, electromagnetic wave pollution, radiation pollution, etc. are also common factors leading to chromosomal translocation. There are many causes of chromosomal abnormalities in germ cells. In cases of miscarriage caused by chromosomal abnormalities, the fetus generally cannot be saved. Even if it is saved, it will be deformed. Therefore, it is not advisable to blindly save the fetus.

3. After chromosomal abnormalities, there is generally no ideal treatment. What people can do is to find the cause of the disease for some patients, and try to avoid any causes such as drugs, dietary pollution, and electromagnetic wave pollution.

Symptoms of abnormal dyeing in boys

1. If abnormal chromosomes are produced in sperm, this diseased sperm will combine with a normal egg to form a fertilized egg with congenital defects.

2. Even if the fertilized egg can survive in the uterine cavity for a period of time, its vitality is extremely poor. It often dies in the early embryonic stage, resulting in stillbirth and miscarriage, and it is difficult to survive to delivery.

3. According to clinical observations, about half of spontaneous abortions are caused by chromosomal abnormalities. Due to the mutation and poor quality of sperm, the result of conception is often repeated pregnancies and miscarriages.

The above is an introduction to the symptoms of chromosomal abnormalities in girls. Generally speaking, the most common manifestations are neurodevelopmental delay, dull eyes, incomplete brain development, jawbone abnormalities, etc. Congenital heart disease is also one of them. The most obvious reaction is the imperfection of certain organs in the body. In such cases, elective abortion is generally recommended.

Causes of Chromosomal Abnormalities in Women

1. Physical factors: the radiation environment in which humans live, including natural radiation and artificial radiation. Natural radiation includes cosmic radiation, earth radiation and radiation from radioactive substances in the human body. Artificial radiation includes radiation radiation and occupational exposure.

2. Chemical factors: People are exposed to various chemical substances in daily life, some of which are natural products and some are artificially synthesized. They can enter the human body through diet, breathing or skin contact, and cause chromosomal abnormalities.

3. Biological factors: When cells in culture are treated with viruses, various types of chromosomal aberrations often occur, including breakage, fragmentation, and exchange.

4. Maternal age effect: When the fetus is 6-7 months old, all oogonia have developed into primary oocytes and entered the nuclear reticulum stage from the prophase of the first meiotic division. At this time, the chromosomes are loosened and stretched again, just like the previous nucleus, and remain so until before ovulation in puberty. This state may be related to the synthesis of yolk.

5. Genetic factors: Chromosomal abnormalities can often show a familial tendency, which suggests that chromosomal abnormalities are related to genetics.

6. Autoimmune diseases: Autoimmune diseases seem to play a role in chromosome nondisjunction. For example, there is a close correlation between increased primary thyroid autoimmune antibodies and familial chromosomal abnormalities.

I believe everyone has a certain understanding of the causes of chromosomal abnormalities in women. We must pay attention to prevention in daily life, because once chromosomal abnormalities occur, the treatment is extremely difficult, and it may also affect the next generation, which is a very troublesome thing. Especially during pregnancy, women should pay more attention to the condition of chromosomes and have timely prenatal check-ups.
