She said: “Although always sad and disappointed, but never desperate, looking at the big belly, I think I won this time! I’m so happy from the bottom of my heart! The baby’s strength is so strong, always kicking me so hard, I think it’s unbelievable, how can there be a little life in such a closed and small space in the stomach, I thank God!” Habitual miscarriage brings pain to many women, it is a kind of spontaneous abortion, which refers to the phenomenon that pregnant women have three or more consecutive times, the embryo stops developing and miscarries during the same period of pregnancy. So, what are the causes of habitual abortion? 1, genetic factors: if the chromosome number or structure of the embryo is abnormal, it will lead to poor embryo development. This is the most common cause of miscarriage, accounting for 60%-70% of the causes of spontaneous abortion, and about 2-4% of habitual abortions are related to genetic factors. 2, maternal disease: women suffering from endocrine disorders, uterine development abnormalities, cervical unhealthy, cervical laxity, uterine fibroids and other gynecological diseases can cause habitual abortion. In addition, suffering from serious internal diseases, such as kidney disease, heart disease, hypothyroidism and other problems, can also occur miscarriage. 3.External factors: Pregnant women who drink a lot of alcohol, smoking (including passive smoking), exposure to chemical poisons, severe noise and vibration, high temperature environment can lead to damage to the placenta and fetus, resulting in miscarriage. Women who experience habitual miscarriage must go to the hospital in time to be examined for uterine or other reproductive organ diseases, serious medical conditions, and their husbands should also be examined to determine if there are any chromosomal abnormalities on either side. In fact, most miscarriages are not related to the mother or the father, but are due to chromosomal abnormalities that occur during the formation of the embryo. This situation is mostly accidental and may happen to the same woman three times in a row. Most couples in which both partners are healthy and there are no chromosomal abnormalities can still have healthy babies after habitual miscarriage. If a woman has problems such as abnormal uterine development, cervical problems, fibroids, kidney disease, heart disease, hypothyroidism, etc., she should be actively treated for these conditions and then consider getting pregnant after they have resolved.
