Patient's question:
How can I take care to avoid miscarriage? I have been pregnant twice, and unfortunately, both times ended in miscarriage. I want to know what causes habitual abortion?Doctor's answer:
Many women suffer from habitual abortion, which causes great harm to both body and mind. What are the reasons for habitual abortion? Below, the editor will introduce the causes of habitual abortion.The reasons for habitual abortion are numerous and relatively complex, mainly including the following aspects:
Endocrine dysfunction
Fertilized eggs can only implant on the uterine wall and develop into a fetus under the action of progesterone. When progesterone secretion is insufficient in the body, the endometrium develops poorly, which affects the development of the fertilized egg and easily leads to abortion. If prostaglandin increases, it can cause frequent contractions of the uterine muscles, also leading to abortion. Hypothyroidism can impair cellular oxidative capacity, thereby affecting embryonic growth and development, resulting in abortion.
Embryonic development abnormalities
Abnormalities in the zygote are the main cause of early abortion. In the first two months of pregnancy, about 80% of miscarriages are due to defects in sperm or eggs, causing the embryo to stop developing to a certain extent. Therefore, in the expelled tissue of such abortions, no primitive embryonic tissue is observed.
Reproductive organ diseases
Uterine malformations, such as bicornuate uterus, septate uterus, and uterine underdevelopment. Pelvic tumors, especially submucosal myomas, can all affect fetal growth and development, leading to abortion. Uterine cervical relaxation or deep lacerations of the cervix can cause premature rupture of membranes and lead to late-term abortion.
