Hyperemesis gravidarum
Abbreviation: HG
Hyperemesis gravidarum (HG) is a severe form of pregnancy nausea and vomiting that goes far beyond typical morning sickness. Women with HG may vomit many times a day, be unable to keep food or water down, and lose more than 5% of their pre-pregnancy body weight. This can lead to dehydration, electrolyte imbalances, and nutritional deficiencies that affect both mother and baby. HG often requires hospitalisation for IV fluids, anti-nausea medication, and monitoring. It is more common in first pregnancies, multiple pregnancies, and in women who experienced it in a previous pregnancy. Early treatment leads to better outcomes.
What This Means for You
Understanding Hyperemesis gravidarum is an important part of your first/second trimester journey. During pregnancy, your care team will use this term regularly. Being familiar with it means you can ask better questions and feel more confident at your antenatal appointments.
