New study identifies cause of morning sickness

New study links morning sickness in pregnant women to hormone.

A new study has identified the cause of morning sickness in pregnant women.

Researchers at the University of Cambridge in England believe it’s linked to a hormone that pregnant mothers are exposed to through the placenta.

How sick the mother feels depends on how much of the hormone is produced by the fetus.

Seventy percent of pregnancies are affected by morning sickness.
