What causes the gestational sac to deform?

After the fertilized egg implants in the woman, it will slowly develop into a gestational sac. Only when the gestational sac is able to develop can the woman become pregnant smoothly. However, some women may have their gestational sac develop very slowly, which makes it easy for the gestational sac to deform. After the gestational sac is deformed, the fetus in the woman's body may not be particularly healthy. So what is the reason for the deformation of the gestational sac?

1. What is a gestational sac?

The gestational sac is only seen in early pregnancy. For women who have regular menstruation of 28 to 30 days, after 35 days of amenorrhea, the gestational sac can be seen in the uterine cavity by B-ultrasound. The diameter of the gestational sac is about 2 cm at 6 weeks of pregnancy and about 5 cm at 10 weeks of pregnancy. It is normal for the gestational sac to be located at the fundus, front wall, back wall, upper part, or middle part of the uterus; it is normal for it to be round, oval, and clear in shape; if the gestational sac is irregular in shape, blurred, and located in the lower part, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.

The gestational sac is the primitive placental tissue, a small embryo wrapped by the amniotic membrane and vascular network. The gestational sac is the initial form of pregnancy. At that time, the fetus has not yet formed, and the fetal heartbeat is already there when the embryonic bud appears. In the second week, the embryo implants in the endometrium. When it develops into the second germ layer, a large cavity called the primary yolk sac appears on the ventral side of the embryonic disc. The yolk sac continues to shrink and degenerate during embryonic development, but the extraembryonic mesoderm on the wall of the yolk sac is the earliest origin of the formation of blood cells, blood vessels and primitive germ cells - the gestational sac, where the fetus will grow in the future.

2. Causes of gestational sac deformation

Irregular sac shape indicates threatened miscarriage, which is caused by many reasons, such as: heredity, genes, semen antibodies, endocrine disorders, deformities, etc. Among these factors, only endocrine disorders cause hormone secretion disorders, which can help to preserve the pregnancy. However, because the baby is too young, the cause cannot be found out. Therefore, no matter what the cause is, we will first prescribe pregnancy-preserving drugs and progesterone to regulate the endocrine system.

The gestational sac is only seen in early pregnancy. Its normal size is about 2 cm in diameter at 1.5 months of pregnancy and about 5 cm at 2.5 months. It is normal for the gestational sac to be located at the fundus, front wall, back wall, upper part, or middle part of the uterus; it is normal for it to be round, oval, and clear in shape; if the gestational sac is irregular in shape, blurred, and located in the lower part, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.

If the threatened miscarriage is due to endocrine reasons, then the pregnancy can be saved if the right treatment is given. So the doctor said that some people were saved and are doing well. This is the situation.

However, if the cause of threatened miscarriage is not endocrine, there is no possibility of artificial intervention, which means that the pregnancy cannot be saved at all. In fact, this was a kind of natural elimination. Later, B-ultrasound showed that there was a gestational sac without echo, confirming fetal arrest.

The above are the reasons for the irregular shape of the gestational sac. In this case, further examination is recommended. You can also check the HCG value and progesterone. In fact, this is a natural elimination. Later, the B-ultrasound showed that there was a gestational sac without echo, confirming the fetal arrest. I hope you have endocrine disorders such as progesterone deficiency and estrogen excess. Even if the baby is not saved due to other reasons, you must not be too sad or angry. This is the choice made by nature to give you a healthy baby.
