What causes the absence of fetal heartbeat during pregnancy?

Generally, the absence of fetal heartbeat during pregnancy may be caused by factors such as early gestational age, intrauterine hypoxia, poor embryonic development, embryonic arrest, or ectopic pregnancy. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment. Detailed analysis is as follows:

1. Early Gestational Age

In early pregnancy, the fetal heartbeat may not have formed yet or may not be detectable. Therefore, it is normal not to hear a fetal heartbeat during early prenatal examinations. This is a normal physiological phenomenon that usually does not require special treatment. It is recommended that pregnant women undergo an ultrasound examination at around 6 weeks of gestation to assess fetal development.

2. Intrauterine Hypoxia

Intrauterine hypoxia may be one of the causes leading to cessation of fetal heartbeat. Insufficient oxygen supply in the intrauterine environment can impair normal embryonic development and cardiac function, resulting in the absence of a detectable fetal heartbeat. In such cases, it is generally recommended to promptly terminate the pregnancy via surgical intervention at a正规 hospital to prevent serious harm to the mother's health.

3. Poor Embryonic Development

Poor embryonic development refers to abnormalities or disruptions during the embryo’s growth in the uterus, which may lead to impaired heart development or failure to establish a normal fetal heartbeat. Doctors may recommend improved nutritional intake, including increased consumption of protein, vitamins, and minerals.

4. Embryonic Arrest

Embryonic arrest refers to the condition in which the embryo stops growing and developing inside the uterus. In this situation, the embryo may fail to develop or sustain a regular heartbeat, resulting in the absence of a fetal heartbeat. Once diagnosed, it is necessary to promptly undergo an induced abortion procedure at a正规 hospital to terminate the pregnancy.

5. Ectopic Pregnancy

Ectopic pregnancy occurs when a fertilized egg implants and develops outside the uterine cavity, most commonly in the fallopian tube. An ectopic pregnancy may result in an undetectable fetal heartbeat because the embryo is not developing normally within the uterus. Pregnant women are advised to go to the hospital for relevant examinations and follow medical advice to undergo surgery to terminate the pregnancy.

In daily life, it is recommended to maintain a positive mindset, avoid spicy, stimulating, and greasy foods, get adequate rest, and develop healthy lifestyle habits.
