What is umbilical cord around neck? Umbilical cord around the neck means that when the fetus is developing in the mother\’s body, due to fetal movement or other reasons, the umbilical cord wraps around the fetus\’s neck, resulting in poor umbilical cord blood flow. This situation is relatively common during pregnancy, but in most cases it does not affect the fetus. However, once the umbilical cord wraps around the neck, you need to pay attention to the physical condition of the fetus. If there is any abnormality, you need to seek medical advice as soon as possible.
