A new study has shown why many women experience nausea and vomiting during pregnancy — and why some women, including the Duchess of Cambridge, become so sick they need to be admitted to hospital. The culprit is a hormone produced by the fetus — a protein known as GDF15. But how sick the mother feels depends on a combination of how much of the hormone is produced by the fetus and how much exposure the mother had to this hormone before becoming pregnant.
