Why does the uterus change from anterior to posterior

If a woman is found to be in the anterior position of the uterus after color Doppler ultrasound examination, but after a period of time, the color Doppler ultrasound is reexamined and found to be in the posterior position of the uterus, it is often due to the change in the position of the uterus after the woman's urine is inflated. This is because the woman's uterus and bladder are close, so after the bladder holds urine, it may affect the position of the uterus. Therefore, the position of the female uterus is not 100% absolutely fixed, but may also show changes, and some women may also change the position of the uterus due to abortion surgery. For example, before the abortion, the color Doppler ultrasound is the anterior position of the uterus, but after the abortion operation, the position of the uterus becomes the posterior position. This is actually a normal physiological performance, and no special treatment is needed.
