Elderly pregnant women are prone to miscarriage, it's all because of this guy

As we all know, older mothers are at one of the high-risk types of pregnancy. Compared with women of appropriate age, older mothers have to bear more risks, such as being prone to pregnancy-induced hypertension, giving birth to deformed babies, and experiencing heavy bleeding and dystocia during delivery. These risks may cause miscarriage. So why are older pregnant women more prone to miscarriage? What are the precautions for older pregnant women? If you want to know more, please continue reading.

Why are older pregnant women more likely to have miscarriages?

1. Age

Babies conceived by older women are more likely to have chromosomal abnormalities, which can lead to miscarriage.

2. Systemic diseases

Systemic infection and high fever during pregnancy can cause uterine contractions and lead to miscarriage.

3. Bad habits

Excessive smoking, alcoholism, excessive drinking of coffee, heroin and other drugs can all cause miscarriage.

4. Exposure to toxic environments

Exposure to certain chemicals such as lead, arsenic, formaldehyde, benzene, ethylene oxide, as well as large amounts of radiation or inhaled anesthetics can increase the risk of miscarriage.

5. Genetic defects

If either spouse has chromosomal abnormalities, it can be passed on to the next generation, and 50% to 60% of embryos with chromosomal abnormalities will result in early spontaneous abortion.

6. Sudden changes in mood

If a pregnant woman is subjected to significant emotional stimulation, excessive sadness, shock, fear, and excessive emotional excitement, it may cause an imbalance in the internal environment of the pregnant woman, prompting uterine contraction and causing miscarriage.

7. History of birth defects or genetic diseases

Have given birth to a baby with a birth defect, or the pregnant woman (or her partner) has a family history of genetic diseases.

8. Uterine and cervical problems

Uterine malformations (such as uterine hypoplasia, double uterus, uterine septum, etc.) and uterine tumors can affect embryo implantation and development and lead to miscarriage. Severe cervical lacerations and relaxation of the internal cervical os lead to premature rupture of membranes and late spontaneous abortion.

9. Certain infectious diseases

The risk of miscarriage increases if a pregnant woman has listeriosis, mumps, rubella, measles, cytomegalovirus infection, parvovirus infection, gonorrhea, HIV infection, or other infectious diseases.

10. Abnormal immune function

Pregnancy is similar to allogeneic transplantation. There is a complex and special immunological relationship between the embryo and the mother, which prevents the embryo from being rejected. If the immune system of both mother and child is not compatible, the mother may reject the embryo and cause miscarriage.
