Why do symptoms of threatened miscarriage occur?

The symptoms of threatened abortion may be related to genetics, environmental factors, one's own physiological conditions and certain underlying diseases. It is necessary to seek medical attention in time to clarify the cause and carry out targeted treatment. Common causes include abnormal embryo development, maternal hormone imbalance, and bad living habits.

1. Genetic factors:

Fetal chromosomal abnormalities are one of the most common causes of threatened miscarriage, accounting for about 50%-60%. If the embryo has serious abnormalities in chromosome structure or number during early development, it will not be able to maintain normal development. These abnormalities may come from the genetic information transmitted by the parents, or they may be mutations in the sperm or egg when they combine. If there are multiple signs of miscarriage in early pregnancy, you should consult a genetics expert for a comprehensive chromosome test.

2. Environmental factors:

Adverse external conditions can increase the risk of miscarriage, such as long-term exposure to toxic chemicals, heavy metals or radioactive radiation; severe air pollution; or even long-term exposure to secondhand smoke. If a pregnant woman is in a stressful living environment, it is recommended to avoid harmful exposure in a timely manner, maintain a good living environment, and receive guidance from a doctor.

3. Physiological factors:

Maternal hormone imbalance, such as insufficient progesterone secretion, can affect the implantation and development of the embryo; uterine structural abnormalities such as uterine septum, double uterus, and intrauterine adhesions can prevent the embryo from developing smoothly; polycystic ovary syndrome and endometrial problems can also affect the health of the embryo in early pregnancy. These conditions need to be clearly diagnosed through ultrasound examinations, hormone testing, etc., and in severe cases, hormone replacement therapy or surgical intervention can be accepted.

4. Underlying diseases and infections:

When the mother suffers from chronic hypertension, diabetes, thyroid dysfunction, lupus erythematosus and other diseases, it may cause placental dysfunction and bring risks to fetal development. Infection with certain pathogens during pregnancy, such as rubella virus, toxoplasmosis, and cytomegalovirus, can also easily induce threatened abortion. Screening for the source of infection through routine prenatal examinations and taking antibiotics or antiviral treatment early can reduce the risk.

5. Unhealthy lifestyle:

Bad living habits such as long-term smoking, drinking, high caffeine intake, staying up late, and high-intensity strenuous exercise can reduce the success rate of embryo implantation and development. Adjusting a healthy lifestyle, such as regular work and rest, avoiding heavy physical labor, and a balanced diet, can help maintain a stable pregnancy.

There may be many reasons for the symptoms of threatened abortion. After diagnosis, personalized intervention measures should be taken according to the specific situation. If you experience abdominal pain, vaginal bleeding and other symptoms in early pregnancy, you should immediately go to the obstetrics department of the hospital to determine the health of the fetus and the mother, and receive treatment or rest as prescribed by the doctor. Maintaining physical and mental health during pregnancy and regular prenatal check-ups are important guarantees for preventing complications, and health management before pregnancy should not be ignored.
