Severe morning sickness during pregnancy, known as hyperemesis gravidarum or HG, is one of the most common reasons for hospitalization during early pregnancy. It’s a condition that can lead to dehydration and weight loss in expecting mothers and has been linked to poor outcomes in babies.
There is currently no cure for HG, and not much can be done for women with this poorly understood condition, other than treating them with intravenous fluids, electrolyte supplementation, antiemetic (anti-nausea) medications, and sometimes steroids. However, a discovery published in late 2023 about HG’s most likely cause may lead to better treatments, and possibly its prevention, in the near future.
