If a woman is pregnant with twins, it is a rare joy for herself and her family. However, some women find that when they go to the hospital for another check-up, they only have one twin left. This not only makes women sad, but also shocked. So, why do twins disappear from the body?
The phenomenon of twin disappearance syndrome occurs when one twin disappears from the body. This situation is not uncommon and is usually caused by abnormal genetic structure during embryonic development. It is the result of fetal developmental abnormalities and survival of the fittest. This is similar to natural abortion, where the fetus stops developing in the uterus.
During the development of two fetuses, if one of them does not develop normally, the two embryos will compete with each other. The weaker one will be absorbed, and by the time the woman gives birth, the absorbed fetus can still be traced. The fetus is like a piece of paper, and its outline can be seen from thin films.
If a woman experiences twin disappearance syndrome in the first three months of pregnancy, there may be a small amount of vaginal bleeding, but this has little impact on the surviving fetus and mother. The surviving fetus can continue to develop. If this situation occurs in the middle and late stages of pregnancy, close observation is necessary to prevent related complications from occurring.
