What are the clinical manifestations of recurrent spontaneous abortion and what are the causes of recurrent spontaneous abortion?

For pregnant women, frequent and recurrent miscarriages are indeed a blow. The occurrence of recurrent miscarriages represents the cause of more than two spontaneous abortions. There are many possible causes, such as luteal insufficiency, hyperprolactinemia or thyroid dysfunction, etc. In short, you must actively receive treatment.

For pregnant women, miscarriage itself is a huge blow. When we talk about miscarriage, we may think of natural miscarriage and artificial abortion. In fact, you will find that in current medicine, there are not only these two types, but also recurrent miscarriage. So what symptoms will this disease have? Let's take a look at the clinical manifestations of recurrent miscarriage.
1. Clinical manifestations of recurrent spontaneous abortion <br/>There are many overall manifestations of recurrent spontaneous abortion, including two or more consecutive spontaneous abortions, and manifestations of abortion include postmenopausal vaginal bleeding and abdominal pain. Of course, not all women may experience these symptoms, and many female friends will not show any symptoms at all.
2. Causes of recurrent spontaneous abortion
1. Luteal insufficiency <br/>The incidence of luteal insufficiency is 23%-60%. The progesterone in the luteal phase is less than 15ng/ml, resulting in poor decidual response during pregnancy. 2-3 cycles of luteal function are insufficient to be included in the diagnosis.
2. Polycystic ovary syndrome <br/>About 58% of people with recurrent miscarriage may suffer from polycystic ovary syndrome. During this process, they may be more prone to miscarriage due to high luteinizing hormone.
3. Hyperprolactinemia <br/>High prolactin inhibits luteinization and steroid hormones in granulosa cells, leading to luteal dysfunction and decreased egg quality. Some scholars have found that prolactin can reduce the secretion of early human placental gonadotropin.
4. Thyroid dysfunction : Thyroid disease and hypothyroidism are associated with recurrent spontaneous abortion. It is also suggested that recurrent spontaneous abortion is related to the presence of thyroid antibodies. In addition, according to research, some diabetic patients may also experience recurrent miscarriage.
5. Uterine malformation
15%-20% of recurrent spontaneous abortions are related to uterine malformations, among which uterine hypoplasia is the most likely cause of recurrent miscarriages, leading to late miscarriages and premature births, accounting for 8% of recurrent miscarriages. If a woman has uterine fibroids and the volume of the uterine fibroids exceeds 5 cm, she may also experience recurrent miscarriages.
