Tools for HG

Weight Loss Calculator

Women with HG often lose 5% of their body weight or more in early pregnancy.

Calculate the percentage you have lost to see how severe your loss is. Excessive and rapid weight loss is unhealthy regardless of your pre-pregnancy weight. So those who are overweight will still become vitamin deficient quickly and should be treated with fluids and IV vitamins at a minimum.

Want to understand more about Hyperemesis Gravidarum (HG)?

Hyperemesis Gravidarum is not morning sickness. HG is defined as a potentially life-threatening pregnancy disease that may cause weight loss, malnutrition, dehydration, and debility due to severe nausea and/or vomiting, and may cause long-term health issues for mother and baby(ies). Signs, symptoms, and treatments for HG are shared in this comparison to morning sickness.

HyperEmesis Level Prediction (HELP) Score Assessment

Nausea and vomiting in pregnancy (NVP) is on a spectrum from morning sickness on one end to hyperemesis gravidarum (HG) on the other. Unlike those with morning sickness, people with HG generally have inadequate food or fluid much of the time and cannot do many of their normal activities most days.

​

This validated scoring tool can be used to determine whether HG symptoms are mild, moderate, or severe. Scores reflect the severity of hyperemesis gravidarum, or severe nausea and vomiting during pregnancy (pregnancy sickness).
