HG Awareness Day – May 15, 2025

HG Awareness Day is observed annually on May 15 to increase awareness of the pregnancy complication hyperemesis gravidarum. Hyperemesis gravidarum (H.G.) is a misunderstood condition that’s often confused with morning sickness. H.G. symptoms, which are nausea and vomiting, are more severe than morning sickness that can lead to dehydration and weight loss. H.G. is potentially life-threatening, and it affects 1% of pregnancies. Besides increasing understanding of this pregnancy complication, H.G. Awareness Day aims to build a broader community for H.G. survivors.

History of HG Awareness Day

HG Awareness Day was first held by the HER Foundation on May 15, 2012. The HER Foundation is a nonprofit charity established in 2003 by Kimber Wakefield MacGibbon, Ann Marie King, and Jeremy King — both MacGibbon and Marie are H.G. survivors. It was in 2000 when MacGibbon put the first comprehensive site about HG online, dedicated to helping women suffering from H.G. and those who have survived it. The HER Foundation is the leading website for H.G. information. The HER Foundation provides support, advocacy, research, and education to all women who are suffering from H.G.

Hyperemesis gravidarum is said to be the leading cause of hospitalization in early pregnancy. It is defined as a potentially life-threatening pregnancy complication. Often confused with morning sickness, H.G. symptoms include more severe nausea and vomiting. H.G. may also cause dehydration, weight loss, malnutrition, and even long-term health issues for mothers and babies. If given early medical care to manage the symptoms and minimize nutritional deficiencies, there is a high chance for both the mother and the baby to be healthier. If not, H.G. can lead to premature labor.

There are initial signs that a woman is developing H.G. They commonly include weight loss of two pounds weekly; recurrent ketosis; frequent and/or severe nausea and/or vomiting; dehydration; severe fatigue; and inability to work. The most effective treatments for H.G. are nutritional therapy, I.V. fluids, bed rest, and medications. Since each woman responds differently to treatments, multiple medications may be needed. The recovery from H.G. takes an average of four to six months. But it may take a few years if the H.G. was severe and prolonged due to malnutrition.
