Will the fetus still stop growing if there is a fetal heartbeat or fetal bud at 8 weeks of pregnancy?

When a woman is 8 weeks pregnant, she will have fetal heartbeats and fetal buds. At this time, she will feel more at ease after the examination. However, women should know that they should be vigilant throughout the whole process. Many women have fetal arrest after fetal heartbeats and fetal buds are found in the early pregnancy. So, will the fetal arrest still occur if there are fetal heartbeats and fetal buds in the 8th week of pregnancy?

Will the fetus still stop growing if there is a fetal heartbeat or fetal bud at 8 weeks of pregnancy?

Even if there is a fetal heartbeat and embryo bud at 88 weeks of pregnancy, it is still possible for embryonic arrest to occur.

Not all embryos can grow normally after the fetal heart appears. However, compared with before the appearance of fetal heartbeat, the risk of embryonic arrest after the appearance of fetal heartbeat will be significantly reduced, and the reasons for arrest before the appearance of fetal heartbeat may be somewhat different.

Embryonic arrest before the presence of fetal heartbeat is mostly due to genetic abnormalities in the embryo itself, and such embryos usually result in miscarriage at a relatively early stage. When embryonic arrest occurs after the presence of fetal heartbeat, we may consider more maternal or environmental factors. If the mother has some endocrine or immune diseases, it may cause fetal arrest. Exposure to toxic, harmful and radioactive substances, environmental pollution, etc. may also cause the embryo to stop developing.

What are the common causes of fetal arrest?

The main reason for embryonic development to stop is fetal chromosomal abnormalities, including abnormal numbers and structures of chromosomes, followed by maternal factors. For example, if the pregnant woman has systemic infectious diseases complicated by high fever or viral infection, heart failure, hypertension, severe malnutrition, etc., all of which can cause the embryo to stop developing. Pregnant women with endocrine abnormalities, such as severe luteal insufficiency, uncorrected hypothyroidism, and severe uncontrolled diabetes mellitus may also cause the embryo to stop developing. When combined with uterine abnormalities, such as uterine septum, intrauterine adhesions, submucous uterine fibroids and other diseases, the intrauterine space may be limited and affect embryonic development, eventually causing the embryo to stop developing. Some pregnant women who smoke excessively, drink alcohol, or take drugs such as morphine, caffeine, heroin, etc., may also cause the fetus to stop developing. When pregnant women are exposed to excessive amounts of chemicals such as formaldehyde, the fetus may stop developing.
