Next, I will talk to you about the hidden dangers of yolk sac enlargement and some suggestions.

Yolk sac: After the embryo develops body folds, the archenteron is clearly divided into the archenteron inside the embryo and the yolk sac outside the embryo, which contains a large amount of yolk. The wall of the yolk sac is formed by the extraembryonic endoderm and extraembryonic mesoderm. It is formed by the continuous proliferation of endoderm cells after one week of embryonic development and is located in the amniotic sac. Generally, it can be seen by B-ultrasound around the 6th month of pregnancy. It appears as regular small circular echoes with an average diameter of 5.6 mm. As the fetus grows, the contents of the gestational sac increase and the yolk sac becomes blurred or disappears on the sonogram.

An enlarged yolk sac is one of the diseases caused by hormone imbalance, which is caused by excessive corpus luteum function. It does not require treatment, just increase exercise, adjust your diet, and make your eating and sleeping habits regular. An enlarged yolk sac may be a symptom caused by tumorous hyperplasia of the yolk sac.

The yolk sac mainly supplies blood to the embryo. If it is an early pregnancy, you must wait at least 8 weeks to check the heart tube pulsation. Only if there is a heart tube pulsation can it be confirmed that the embryo is alive. Therefore, female friends with enlarged yolk sac are advised to pay attention to rest, eat a proper diet and have balanced nutrition during pregnancy.

The physical condition of pregnant mothers must be taken seriously, and they must go for regular physical examinations to determine the condition of the child. If the yolk sac enlarges, don't worry too much. Just pay attention to diet and rest. I hope my sharing will be helpful to everyone. I also hope that every expectant mother can be in good health.
