What are the causes of threatened miscarriage?

The treatment of threatened abortion depends on the specific cause, which includes genetic, environmental, physiological, traumatic and pathological factors. Treatment methods include medication, surgery and lifestyle adjustments.

1. Genetic factors: Chromosomal abnormalities are a common genetic cause of threatened miscarriage. Genetic counseling and chromosome testing are recommended, and if necessary, preimplantation genetic diagnosis (PGD) is performed to reduce the risk of miscarriage.

2. Environmental factors: Exposure to harmful chemicals, radiation or infection may increase the risk of miscarriage. Avoid contact with harmful substances, maintain good hygiene habits, have regular prenatal checkups, and detect and treat infections in a timely manner.

3. Physiological factors: Maternal health conditions such as endocrine disorders, uterine malformations or immune system abnormalities may lead to miscarriage. Improve maternal health through hormone therapy, surgical correction or immune regulation therapy.

4. Trauma: External impact on the abdomen or strenuous exercise may cause miscarriage. Avoid strenuous exercise and abdominal trauma, and take bed rest and fetal preservation treatment when necessary.

5. Pathological factors: Diseases such as gestational hypertension, diabetes or thyroid dysfunction may increase the risk of miscarriage. Manage these diseases through medication, diet control and regular monitoring to reduce the risk of miscarriage.

There are many causes of threatened abortion, which require targeted treatment based on the specific circumstances and comprehensive measures to improve the success rate of pregnancy.
