Summary

This study tests whether taking metformin-XR (a diabetes drug) daily before pregnancy can lower the risk and severity of Hyperemesis Gravidarum (HG)—extreme nausea and vomiting in pregnancy—in women aged 18-49 who had HG before and are trying to conceive. Participants either take the drug or join a survey-only group. Researchers will track side effects, HG recurrence, pregnancy outcomes, and newborn health.
