What causes threatened miscarriage?

The causes of threatened abortion mainly include genetic, environmental, physiological, traumatic and pathological factors, and pregnancy preservation treatment or medical intervention should be adopted according to the specific causes.

1. Genetic factors

Chromosomal abnormalities are one of the common causes of threatened miscarriage. During the development of the embryo, if the chromosome structure or number is abnormal, the embryo may not develop normally, thus causing miscarriage. If both spouses have a family history of genetic diseases, it is recommended to undergo genetic testing before pregnancy to assess the risk.

2. Environmental factors

The impact of the external environment on pregnant women and fetuses cannot be ignored. Long-term exposure to harmful chemicals such as formaldehyde, benzene, radiation or high temperature environment may increase the risk of miscarriage. Pregnant women should avoid contact with toxic substances, keep their living environment clean and ventilated, and stay away from radiation sources.

3. Physiological factors

The physical condition of the pregnant woman herself can also affect pregnancy. Diseases such as luteal insufficiency, thyroid dysfunction, diabetes or hypertension may lead to miscarriage. A comprehensive physical examination should be conducted before pregnancy, and problems should be treated promptly. During pregnancy, blood sugar, blood pressure and other indicators should be monitored regularly to ensure good health.

4. Trauma

External impact on the abdomen or strenuous exercise may cause threatened abortion. Pregnant women should avoid strenuous activities, protect their abdomen, and avoid falls or collisions. If an accident occurs, you need to see a doctor immediately to check the fetus.

5. Pathological factors

Infection is another important cause of threatened abortion. Bacterial, viral or parasitic infections may affect fetal development. During pregnancy, you should pay attention to personal hygiene and avoid contact with sources of infection. If you have symptoms such as fever or abdominal pain, you should seek medical treatment in time.

Treatment:

Drug treatment: progesterone supplementation, anti-infective drugs, thyroid hormone regulating drugs, etc.

Surgical treatment: cervical cerclage, uterine curettage, etc., are suitable for severe cases.

Dietary adjustment: Eat more foods rich in protein and vitamins, such as eggs, milk, and green leafy vegetables.

Lifestyle: Keep a happy mood, avoid overwork, and do some light exercise such as walking.

The causes of threatened abortion are complex and varied, and targeted measures need to be taken according to the specific situation. If symptoms such as vaginal bleeding and abdominal pain occur, you should seek medical attention in time to avoid delaying treatment. Maintaining a good living habit and mentality during pregnancy can help reduce the risk of miscarriage.
