What pre-pregnancy examinations should be done and which department should be consulted when preparing for pregnancy after missed abortion?

Before preparing for pregnancy again after a missed miscarriage, it is recommended to go to the gynecology or reproductive medicine department for a comprehensive pre-pregnancy examination, including assessment of hormone levels, uterine recovery, immune factors, etc., to reduce the risk of another miscarriage.

1. Hormone level test

Missed abortion may be related to endocrine disorders, especially luteal insufficiency or thyroid dysfunction. It is recommended to check six sex hormones, thyroid function TSH, T3, T4, etc. to ensure that hormone levels are normal. If abnormalities are found, medication should be taken under the guidance of a doctor, such as supplementing progesterone or adjusting thyroid medication.

2. Assessment of uterine recovery

Missed abortion may damage the endometrium and affect subsequent pregnancy. It is recommended to perform B-ultrasound examination to observe the thickness of the endometrium, the morphology of the uterine cavity, and whether there are adhesions. If necessary, hysteroscopy can be performed to directly evaluate the uterine cavity environment. If uterine cavity adhesions are found, hysteroscopic surgery is required to separate the adhesions and promote endometrial repair.

3. Immune factor screening

Some missed abortions are related to immune factors, such as antiphospholipid syndrome or autoimmune diseases. It is recommended to check indicators such as antiphospholipid antibodies and antinuclear antibodies. If it is confirmed to be immune-related abortion, low molecular weight heparin or aspirin and other drugs can be used for intervention under the guidance of a doctor.

4. Genetic factors screening

Missed abortion may be related to chromosomal abnormalities in the embryo. It is recommended that the couple undergo chromosomal karyotype analysis to rule out genetic factors. If chromosomal abnormalities are found, the third-generation IVF technology PGT can be considered to screen healthy embryos to reduce the risk of miscarriage.

5. Lifestyle Adjustment

During the pregnancy preparation period, it is recommended to maintain a healthy lifestyle. Eat more foods rich in folic acid, iron, and vitamins, such as green leafy vegetables, lean meat, and beans. Avoid high-sugar and high-fat diets. Moderate exercise, such as walking and yoga, can help improve physical fitness. At the same time, quit smoking and drinking, and avoid contact with harmful substances.

Preparing for pregnancy again after a missed abortion requires a comprehensive assessment of the physical condition, targeted conditioning and treatment. Scientific pre-pregnancy examinations and health management can effectively reduce the risk of miscarriage again and increase the success rate of pregnancy. It is recommended to develop a personalized pregnancy preparation plan under the guidance of a doctor to ensure the health of mother and baby.
