For generations, the suffering of women with hyperemesis gravidarum was folded into a story of psychological fragility rather than biological reality. Now, the largest genetic study of the condition ever conducted has identified ten genes — six of them newly discovered — that root this severe pregnancy illness firmly in the genome, doubling what science knew and pointing toward treatments as precise as the biology they address. The work, published in Nature Genetics and drawing on nearly 11,000 affected women across multiple ancestries, does not merely advance medicine; it corrects a long inju
Genetic study identifies nine new genes linked to severe pregnancy sickness
Hyperemesis gravidarum affects approximately 2% of pregnant women, causing severe malnutrition and threatening the health of both mother and baby in serious cases.
