What circumstances can lead to habitual miscarriage?

Habitual miscarriage is also a common disease during pregnancy and childbirth. In general, we call more than three spontaneous abortions after pregnancy habitual abortion. Because this situation is still a relatively common situation in today's society, it is worth our vigilance. This is an issue that women who are preparing to have a baby or have just become pregnant should pay the most attention to. So what circumstances can lead to habitual miscarriage? Let’s take a look together.

1. Luteal insufficiency: After the ovary ruptures and ovulation, a corpus luteum will be formed. This corpus luteum can secrete progesterone and estrogen. If it is luteal insufficiency, it will lead to insufficient estrogen and progesterone, which cannot meet the needs of pregnancy and cause miscarriage in patients.

2. Abnormal uterine development: Congenital uterine malformations such as saddle-shaped uterus, microuterus, bicornuate uterus, and acquired uterine diseases such as uterine fibroids and intrauterine adhesions can also lead to miscarriage in pregnant women.

3. Genetic factors: If a couple is married to close relatives, any chromosomal abnormality in either spouse may cause abnormalities in the embryo, resulting in the embryo not surviving and miscarriage. There may also be malformations, fetal developmental delays, etc., which are all causes of miscarriage.

4. Relaxation of the internal os of the cervix: Due to surgical injuries or congenital developmental abnormalities, the internal os of the cervix can cause dilation. In the middle and late stages of pregnancy, the amount of amniotic fluid will increase, and the fetus will grow slowly, increasing the pressure in the uterine cavity. Once the fetal sac protrudes from the internal os of the cervix, it will cause the cervical canal to shorten and dilate. Once the pressure increases to a certain level, the fetus will be expelled and miscarriage will occur.

5. Incompatibility of blood types between mother and fetus: If the blood types of the mother and fetus are incompatible, the fetus will obtain antigens from the father and will produce antibodies after entering the mother's body. These antibodies will enter the fetal blood circulation through the placenta and produce immune effects, which may lead to fetal death in severe cases. This is a late miscarriage.

6. Having children too late: Under such great social pressure, many couples do not want to have children too early. They always want to try for a few years before having another child. However, when they want children, they just cannot get pregnant and suffer from habitual miscarriage. As age increases and the open environment of modern society affects the body, the body is also greatly affected. For example, taking too many contraceptives and having too many abortions can cause habitual miscarriage.

In fact, both women and men need to understand under what circumstances may lead to habitual miscarriage. Only in this way can we prevent it before it happens. For women who know that they will have habitual miscarriages, my advice is to go to the hospital to see if there is any disease in the uterus or reproductive organs. Both husband and wife must go for a check-up to make sure it is not a chromosomal problem.
