What are the symptoms of fetal malformation in pregnant women?

In fact, cases of fetal malformations are quite common in real life, because there are many factors that affect them, such as drug effects, environmental influences, genetic mutations, etc. If the fetus is deformed, the pregnant woman may sometimes experience discomfort, such as fever. Pregnant women should have regular prenatal checkups so that they can understand the development of the fetus in a timely manner .

1. Pregnant women with high fever in early pregnancy

Even if a woman who has a high fever in early pregnancy does not have obvious external deformities in her child, the development of brain tissue may be adversely affected, manifesting as mental retardation and poor learning and reaction abilities. This type of mental retardation is caused by high fever which causes the death of fetal brain nerve cells and reduces the number of brain nerve cells. This type of mental retardation is irreversible. Of course, high fever causing fetal malformations is also related to the pregnant woman's sensitivity to high fever and other factors.

Pregnant women may develop various infectious diseases. And all of them had elevated body temperature. The most common one is the common cold, in addition there are diseases such as tonsillitis, pneumonia, tuberculosis, cholecystitis, acute pyelonephritis, acute appendicitis, chorioamnionitis, etc. In addition to causing fever, these inflammations also have some other symptoms and manifestations. Viral infection in early pregnancy can cause miscarriage, embryonic development arrest or teratogenesis; acute inflammation in late pregnancy can induce uterine contractions, leading to premature birth, fetal intrauterine hypoxia, etc. Therefore, once a pregnant woman has a fever, she should go to the hospital immediately to find out the cause, determine whether the pregnancy can continue, and receive symptomatic treatment.

After confirming pregnancy, the mother should use as little or no medication as possible. Although not all drugs are harmful to the fetus, if a pregnant woman's fever is not treated, it may cause greater harm to the fetus.

Fever is divided into three categories: low-grade fever (below 38°C), moderate fever (below 39°C), and high fever (above 39°C). Infectious diseases can cause fever in the body. Severe infections may cause not only chills and high fever, but also toxemia, sepsis, shock, and coma.

Some pregnant women have fever in the early stages of pregnancy, fearing that it may be harmful to the health of the fetus. In this regard, we must first find out the cause of the fever. Short-term low fever does not cause much harm to the fetus; long-term fever or high fever will not only cause organ dysfunction in pregnant women, but can also stimulate uterine contractions or cause uterine infection and miscarriage. Bacterial toxins and viruses can infect the normal and developing organs, causing fetal malformation or death. In addition, simple high fever in pregnant women can also cause malformations.

Clinical studies have shown that 60% of early miscarriages are caused by embryonic maldevelopment, and maldeveloped embryos will die sooner or later, so there is no need to blindly preserve the fetus. Excessive use of progestins to preserve pregnancy may be ineffective or may put the fetus at risk of developing malformations of its sexual organs.

What should pregnant mothers do?

(1) In the early stages of pregnancy, special attention should be paid to preventing viral infections, such as rubella and influenza, because viruses can cause teratogenesis. Therefore, pregnant mothers should avoid various causes that can cause fever.

(2) If a pregnant mother has a high fever for a long time, it is recommended to seek medical advice to see if an abortion is necessary for the sake of caution.

2. Pregnant women who often get close to cats and dogs

Few people know that cats carrying bacteria are also a source of infectious diseases that pose a great threat to fetal malformations, and cat feces are the main route of transmission of this malignant infectious disease. According to relevant data, in the UK, about 40% of pregnant women who are infected have adverse consequences for their babies due to their close proximity to cats, and about 500 babies are killed by cats every year.

Among household pets, what we are more concerned about is that there may be a type of parasite called "Toxoplasma" in cat feces that can be transmitted to humans. If the Toxoplasma oocysts excreted by animals contaminate water and food, it can cause Toxoplasma infection in humans and animals. If a pregnant woman is infected with Toxoplasma gondii, it can easily lead to fetal malformations, brain retardation, and may also cause miscarriage, malformations and stillbirths, as well as neonatal cerebral edema and visual or nervous system dysfunction.

What should pregnant mothers do?

(1) Since Toxoplasma gondii is transmitted through cat feces, you should be able to rest assured if you leave the cleaning of the cat to your family members during pregnancy. Family members should also pay attention to the cleanliness of their hands.

(2) If the mother is still worried, she can consider temporarily entrusting the child to someone else for care.

(3) In addition to cats and dogs, some people have special pets at home, such as hamsters, birds, etc. In principle, if you want to keep them, the cleaning work should be left to other family members, but it is best to give them to others to take care of them temporarily.
