Big news for people who can get pregnant and the people who care about them (which should be everyone):

"New research published by the journal Nature points to the discovery that a single hormone causes nausea and vomiting in pregnancy: GDF15. Researchers found that the amount of this hormone in a pregnant person’s bloodstream before and during pregnancy determines the severity of the nausea and vomiting. GDF15 is released by the body in response to stress, with the receptors of this hormone rooted in the part of the brain responsible for triggering vomiting."

Trials are already underway - with really good hope for effective treatment and prevention. #Health
