What causes threatened miscarriage and how to treat it

Threatened abortion may be caused by genetic, environmental, physiological and pathological factors. Treatment focuses on preserving the pregnancy and correcting the underlying causes, and intervention must be performed under the guidance of a doctor.

Genetic factors may be one of the root causes of threatened miscarriage, such as chromosomal abnormalities in the embryo, which account for the majority of cases. Environmental factors include long-term exposure to harmful substances, severe stress or high temperature exposure. Physiological factors may involve maternal endocrine disorders, such as luteal insufficiency or hypothyroidism, which can affect the development of the placenta and embryo. Pathological causes such as uterine malformations, cervical insufficiency or severe infections (such as toxoplasmosis) can also have an adverse effect on the duration of pregnancy. Regardless of the possibility, symptoms of threatened miscarriage such as vaginal bleeding or lower abdominal pain require prompt medical confirmation.

Treatment measures are mainly aimed at preserving the fetus. Drug treatment includes the use of progesterone supplements (such as dydrogesterone) to correct luteal insufficiency, injection of human chorionic gonadotropin (HCG) to support pregnancy, and antibiotic treatment for infection. For patients with abnormal maternal hormone levels, reasonable regulation of thyroid function or blood sugar levels is also critical. Lifestyle adjustments are also very important. Bed rest, avoid heavy physical activities, keep a stable mentality, and avoid adverse environmental factors if necessary.

To avoid the risk of miscarriage, pre-pregnancy check-ups are very important. Early screening for intrauterine malformations, infection risks and genetic factors can help you develop countermeasures. During pregnancy, you should take good care of your body and strengthen your nutrition, especially by taking foods containing folic acid and iron, such as lean meat and spinach, which can reduce the possibility of placental detachment. If any abnormalities occur, do not delay and consult a professional doctor as soon as possible to get a clear diagnosis and take active intervention.
