Does Cord Compression Cause Hiccups?

Development of fetal reflexes, where the fetus is trying to suck fingers or thumb can also cause hiccups. Cord compression can also lead to fetal hiccups when the umbilical cord winds along the fetal neck, limiting the flow of oxygen.

Why does cord compression cause hiccups?

There are several problems with the study that suggests hiccups are associated with potentially dangerous umbilical cord compression. The researcher speculates that hiccups are a hyper-reactive response to reduce blood flow from a knotted or compressed umbilical cord.

What are signs of umbilical cord compression?

Signs of umbilical cord compression may include less activity from the baby, observed as a decrease in movement, or an irregular heart beat, which can be observed by fetal heart monitoring. Common causes of umbilical cord compression include: nuchal cords, true knots, and umbilical cord prolapse.
