Embryo arrest, also known as missed miscarriage, refers to the absence of a fetal heartbeat in the early stages of pregnancy due to various factors affecting the gestational sac. Typically, if no fetal heartbeat and embryo are detected during an ultrasound at about 8 to 9 weeks of pregnancy, it can be diagnosed as embryo arrest. Currently, there are many reasons for embryo arrest in clinical practice, but many pregnant women look for causes in their daily life, such as diet and exercise. However, these factors are largely unrelated to embryo arrest. While diet plays a very important role in human health, the growth and development of an embryo are mainly influenced by its own genetic material, endocrine, and coagulation factors, which are generally unrelated to diet. Therefore, when embryo arrest occurs, one should not look for reasons in diet or other daily life factors; instead, it is advisable to undergo targeted medical examinations to determine the specific cause.
