What Factors Can Lead to Miscarriage?
Miscarriage refers to the termination of pregnancy when the gestational age is less than 28 weeks and the fetal weight is less than 1kg. Artificial abortion is caused by human factors, but the following mainly discusses the reasons for spontaneous miscarriage.
First, maternal factors. If the mother suffers from severe chronic systemic diseases such as severe hypertension, diabetes, heart failure, or if the pregnant woman's constitution is weak, any acute exacerbation of chronic diseases may lead to miscarriage. Additionally, congenital abnormalities of female reproductive organs, such as bicornuate uterus, septate uterus, can affect fetal development and make early pregnancy susceptible to fetal demise, resulting in a miscarriage. Furthermore, if both parents or one of them has chromosomal abnormalities, it can also lead to recurrent miscarriages.
Second, embryo-related factors. In the evolutionary law of species, survival of the fittest prevails. During the embryonic stage, if the embryo or fetus has chromosomal abnormalities, such as triploidy, aneuploidy, chromosomal balanced translocations, inversions, missing or repeated gene segments, or chromosomal abnormalities, they will naturally be eliminated, resulting in fetal demise and spontaneous abortion.
Third, environmental factors during pregnancy. Pregnancy is a special period, and if not adequately protected, frequent or high-dose exposure to harmful chemicals such as arsenic, benzene, formaldehyde, or long-term exposure to physical factors like radiation, noise, can sometimes lead to miscarriage.
Fourth, various negligence or accidents during pregnancy. Using highly stimulating foods or medications prohibited for pregnant women during pregnancy can easily lead to spontaneous miscarriage. Additionally, during the mid-pregnancy stage, accidents like slipping, falling, or abdominal trauma from accidents can also cause spontaneous miscarriage.
