What is the most common cause of early abortion?

The most common cause of early abortion is chromosomal abnormalities.

In early embryo development, if there are abnormal numbers or structures of chromosomes, such as chromosome deletion, duplication, translocation, etc., it will seriously affect the normal development of embryos, making it difficult to continue to survive and lead to abortion. This situation may stem from mutations in the process of gamete formation, or it may be caused by genetic factors. In addition, maternal systemic diseases, such as severe infection, high fever, anemia, chronic nephritis, etc., will affect maternal health and internal environment, not conducive to the growth and development of embryos, increase the risk of early abortion. In addition, endocrine disorders, such as luteal insufficiency, thyroid dysfunction, etc., will affect hormone levels to support embryos, easy to cause abortion.

In preparation for pregnancy and pregnancy, attention should be paid to maintaining good living habits and health status, timely examination and diagnosis, in order to take appropriate measures to reduce the risk of abortion.
