If an embryo stops developing but is not miscarried, the retained embryonic tissue can disrupt the clotting function in the pregnant woman’s body over time, leading to a condition called a missed miscarriage. Therefore, after a missed miscarriage occurs, it is important to check the duration it has been retained. If it has been a considerable amount of time, clotting function should be examined. If clotting is still within normal ranges, it is crucial to expedite the process allowing the woman to expel the non-viable embryonic tissue as soon as possible, which is beneficial for her health.

Why does embryonic arrest cause back pain?

After the embryo's development stops, the uterus will induce contractions, leading to pain in the lower back and abdomen, which is considered normal. Following the cessation of the embryo's development, there will be episodic pain in the lower abdomen accompanied by back pain, primarily to facilitate the process of embryo cessation and to promote the expulsion of the gestational sac. In such cases, it is important to rest, observe the expulsion of embryonic tissue, and be mindful of vaginal bleeding. Rest should be prioritized, avoid overexertion, strengthen nutrition, maintain a regular routine, and, if necessary, undergo a uterine cleaning procedure.

Will the pregnancy test strip become lighter if the embryo stops developing?

After embryonic arrest, early pregnancy tests will show a fading phenomenon. This is because the embryo has stopped developing, and the level of human chorionic gonadotropin (HCG) in the body no longer rises but instead significantly declines. Early pregnancy tests work by detecting the amount of HCG in the urine. When embryonic arrest causes HCG levels to decrease, the result on pregnancy tests will gradually become fainter, even turning negative. It is advised that in cases of embryonic arrest, prompt miscarriage management or uterine evacuation should be conducted to prevent potential inflammatory gynecological conditions and impacts on the woman's clotting function.

Does an embryonic arrest require a dilation and curettage?

According to the different intervention methods, surgical abortion is needed during an abortion procedure, while medical abortion might not be necessary. Embryonic arrest, also known as missed abortion, occurs during pregnancy due to various factors which result in the absence of a fetal heartbeat in the gestational sac or fetus. Most cases of embryonic arrest occur during early pregnancy. If no fetal heartbeat is observed by the 9th week of pregnancy, it is diagnosed as embryonic arrest. Once embryonic growth ceases, it is crucial to intervene artificially as soon as possible to expel the gestational sac from the uterus. Common methods of artificial intervention include medical abortion and surgical abortion. If surgical abortion is chosen for an embryonic arrest, it involves direct curettage or evacuation of the uterus. Embryonic arrest can also be treated with medical abortion, which involves taking oral medication to stimulate uterine contractions, soften the cervix, and expel the gestational sac from the uterus. A follow-up is required about two weeks after the abortion. If there is no residual material in the uterine cavity, then curettage is not necessary; however, if substantive residuals or blood signals are present inside the uterine cavity, then curettage is needed.

What are the reasons for two instances of embryonic arrest?

According to current medical viewpoints, there are various reasons for embryonic arrest, but in 50% of cases, the cause is unknown. Identified causes can generally be divided into several categories such as chromosomal issues, maternal metabolic issues including thyroid disorders, diabetes, and polycystic ovary syndrome. Additionally, immune factors such as lupus erythematosus or Sjögren's syndrome, along with abnormal antibodies, are also reasons. Furthermore, abnormal maternal anatomical structures, like abnormal uterine development, can lead to embryonic arrest. Paternal factors, such as abnormal sperm, can also result in embryonic arrest. Upon encountering embryonic arrest, if it occurs once, it can be observed initially. However, if there are two or more instances, comprehensive examinations for both partners are necessary, including chromosomal tests.
