Early data hint that the common diabetes drug metformin may greatly reduce the risk of a severe form of morning sickness that affects thousands of pregnant people each year.
This form of morning sickness — called hyperemesis gravidarum (HG), or hyperemesis — can lead to complications during pregnancy, such as weight loss, dehydration and electrolyte imbalance, as well as long-term health issues for both mother and baby. It's also common for people who had hyperemesis in their first pregnancy to experience it again in subsequent pregnancies.
