A nuchal cord occurs when the umbilical cord wraps around the fetal neck completely or for 360 degrees.

Nuchal cords are common during pregnancy, with incidences recorded at around 12 percent at 24–26 weeks, reaching 37 percent at full term. Trusted Source.

When an umbilical cord becomes wrapped around the neck, the loop is referred to as the nuchal cord. The term “nuchal” refers to the nape or back of the neck.

Fast facts on the nuchal chord:
▪️ The umbilical cord carries nutrients and oxygen to the fetus in the mother’s womb.
▪️ A nuchal cord might interrupt the flow of oxygen and nutrients to the fetus and cause complications.
▪️ Fortunately, most nuchal cords will resolve before delivery.
▪️ If there is concern about the cord’s enlargement, a baby may be delivered by cesarean.
▪️ Even in cases where they do not resolve, the potential for problems is low.

The main cause of a nuchal cord is excessive fetal movement.

Other medical reasons why cords may move around the neck of a fetus or may result in loose knots include:
an abnormally long umbilical cord
▪️a weak cord structure
excessive amniotic fluid
having twins or multiples<end_of_turn><eos>
