After pregnancy, some pregnant women may experience threatened miscarriage. For them, it is necessary to understand the causes of threatened miscarriage so that treatment can be targeted to prevent it. So, what are the reasons for threatened miscarriage? What should I do about threatened miscarriage? Please refer to the specific introduction below.
Reasons for threatened miscarriage
1. Systemic diseases
High fever during systemic infection can induce uterine contractions and lead to miscarriage; Certain known pathogen infections such as Toxoplasma gondii, herpes simplex, Mycoplasma hominis, Ureaplasma urealyticum, and Cytomegalovirus are associated with miscarriage. Ischemic and hypoxic diseases such as heart failure, severe anemia, hypertension, chronic nephritis, and severe malnutrition in pregnant women can also lead to miscarriage.
2. Blood type incompatibility
Due to previous pregnancies or transfusions of RH factors or incompatible ABO blood type factors, antibodies are produced in the mother's body. When this pregnancy enters the fetus from the placenta and aggregates with red blood cells, hemolysis occurs, resulting in miscarriage.
3. Endocrine disorders
Excessive estrogen and insufficient progesterone are the causes of early miscarriage. Because during the 12-14 weeks of pregnancy, the placenta is forming to replace the corpus luteum function, which can lead to hormonal imbalances. In addition, the lack of thyroxine, which hinders the oxidation process of cells, as well as hyperthyroidism and diabetes, can lead to abortion.
4. Chromosomal abnormalities
Chromosomal studies have found that 60% of naturally aborted fetuses have karyotype abnormalities. Individuals with abnormal karyotype often have structural abnormalities such as fetal or placental abnormalities.
5. Abnormal emotions
Excessive tension, fear, and severe mental stimulation can all cause miscarriage.
What to do about threatened miscarriage
The occurrence of threatened miscarriage often depends on whether the embryo is abnormal. If the embryo is normal and after rest and treatment, the cause of miscarriage is eliminated, bleeding stops, and pregnancy can continue. But most miscarriages are caused by embryonic abnormalities, so ultimately miscarriage is still necessary. If pregnant women find signs of threatened miscarriage, they should go to the hospital for examination as soon as possible to determine the cause and the condition of the fetus. Treatment should be carried out according to the doctor's diagnosis. Pregnant women should also do a good job in prenatal care to avoid miscarriage.
What are the causes of threatened miscarriage? The above introduces five common causes of threatened miscarriage. If the embryo is normal and the causes are eliminated, there is a great hope that pregnancy can continue. If threatened miscarriage is caused by embryonic abnormalities, the ultimate result is termination of pregnancy.
