Metformin Reimagined: A 100-Year-Old Drug Tackles Hyperemesis Gravidarum

A health feature follows researchers and patients exploring metformin, a diabetes drug, as a potential preventive treatment for hyperemesis gravidarum (HG) by modulating the nausea-related hormone GDF15. Early observational data suggest taking metformin before conception may significantly reduce HG risk, with clinical trials in the works. The drug’s affordability, safety history, and broad off-label use—ranging from fertility in PCOS to obesity and potential antiaging effects—have spurred widespread interest, though more rigorous research is needed. The piece also shares the lived experience of HG and a patient hopeful that metformin could improve future pregnancies.
