Umbilical Cord Knots In Pregnancy - What Should You Know?

The umbilical cord gets knotted due to the movement of the baby inside the womb. This usually happens early on during the pregnancy and is mostly harmless. The umbilical cord knots itself when the baby passes through a loop. The chances of the umbilical cord getting knotted are more when the amniotic fluid in the womb is present in excess and if the baby is quite active inside.

True Knots And False Knots 

Not all knots are dangerous. Some knots just look like knots but aren't. Basically, the knots on the umbilical cord can be divided into two types - true knots and the false knots. While true knots are caused due to the looping of the cord due to the baby's activity inside the womb, false knots are just some extra blood vessels looping on each other inside the Wharton's jelly.

How Common Are True Knots During Pregnancy? 

Umbilical cord knots are extremely common during pregnancy, occurring in about one in every 100 pregnancies. Knots are usually caused early on during the pregnancy and often untangle on their own. However, in cases where the knot tightens, the baby's blood supply and be restricted and chances of a miscarriage are high.

What Causes Umbilical Cord Knots? 

1) If the umbilical cord is abnormally large, there are high chances of the cord being knotted inside the womb. 

2) Increased activity of the foetus can further lead to it looping around the cord resulting in an umbilical knot. 

3) This phenomenon is known to be extremely common if there is more of amniotic fluid present inside the womb. 

4) Also, if the size of the foetus is small, the umbilical cord may get entangled due to its activity.
