An enlarged yolk sac does not necessarily mean that the pregnancy will be terminated, and there will be individual differences.
Enlargement of the yolk sac is not a symptom of fetal failure, the development of the embryo can not be judged only by the increase or decrease of the yolk sac, but mainly based on the presence or absence of fetal heart and buds, which is the main criterion for the judgment of embryonic failure.
Yolk sac enlargement alone does not have special significance, it is only the description of the imaging, women can through regular obstetric examination, in order to understand the specific development of the fetus, and for the problem of fetal arrest can also make early diagnosis.
It is recommended that women should relax and not be anxious and nervous. Regular diet, maintain sufficient sleep, not to stay up late.
