TL;DR Summary

A study published in the journal Nature has identified a single hormone, GDF15, as the primary cause of severe morning sickness during pregnancy. The hormone's levels in a woman's blood during pregnancy, as well as her exposure to it before pregnancy, determine the severity of her symptoms. Severe morning sickness, known as hyperemesis gravidarum, can lead to malnutrition, weight loss, dehydration, and increased risks for preterm birth and other complications. The discovery could lead to better treatments, including medications to block the hormone's effects in the brain, and potentially even prevention methods for at-risk women.
