Massive Genetic Study Reveals Hidden Causes of Pregnancy Sickness

A large genetic study of 10,974 women with hyperemesis gravidarum and 461,461 controls found 10 associated genes.

Six of the genes are newly identified candidates, expanding the genetic map of severe pregnancy sickness.

The results strengthen evidence that HG is a biological, inherited disorder rather than just a routine pregnancy symptom.

The findings could improve diagnosis and help guide targeted treatments for a condition that can threaten mothers and babies.
