Researchers Identify Six New Genetic Links to Severe Morning Sickness, Offering New Treatment Pathways
Scientists have discovered six new genetic links associated with hyperemesis gravidarum (HG), a severe form of morning sickness affecting about two percent of pregnant women. This study, the largest of its kind, was conducted by the Keck School of Medicine of the University of South Carolina and international collaborators, analyzing genetic data from nearly half a million women. The research confirmed the gene GDF15 as a significant factor in HG and identified nine additional genes, six of which are newly associated with the condition. These findings suggest that genetic variants affecting hormone sensitivity, particularly GDF15, play a crucial role in the severity of nausea during pregnancy. The study also highlights the potential for new treatment pathways, including the use of metformin, a diabetes medication, to manage HG symptoms.
