How does habitual abortion occur?
How does heavy drinking, smoking, and exposure to certain chemicals during pregnancy lead to habitual miscarriage? Additionally, severe noise, vibrations, or high-temperature environments can potentially damage the placenta and fetus, leading to miscarriages.
Some factors, such as genetic ones, are beyond our control. However, environmental conditions that pregnant women are exposed to, along with any pre-existing gynecological conditions they may have, can also cause this condition. These two factors are entirely preventable. So, how exactly does habitual miscarriage occur? Below, experts from the Beijing Armed Police General Hospital provide a detailed explanation of the causes of habitual miscarriage.
How does habitual miscarriage occur? Experts from the Beijing Armed Police General Hospital point out the main reasons for habitual miscarriage include the following:
1. External Factors: Heavy drinking and smoking by pregnant women, as well as exposure to chemical toxins, severe noise and vibrations, or high-temperature environments, can all potentially lead to damage to the placenta and fetus, causing miscarriage.
2. Genetic Factors: If there are abnormalities in the number or structure of the chromosomes in the embryo, it can result in poor embryonic development. This is the most common cause of miscarriage, accounting for 60-70% of natural miscarriages. Approximately 2-4% of habitual miscarriages are related to genetic factors.
3. Maternal Diseases: Conditions such as endocrine disorders, abnormal uterine development, cervical insufficiency, uterine relaxation, uterine fibroids, and other gynecological diseases can all potentially cause miscarriages in women. Furthermore, serious internal medical conditions like kidney disease, heart disease, or hypothyroidism may also lead to miscarriage.
