What is a significant symptom of hyperemesis gravidarum?

Severe nausea and vomiting are hallmark symptoms of hyperemesis gravidarum, a pregnancy complication characterized by extreme nausea that can lead to dehydration, weight loss, and electrolyte imbalances. Unlike typical morning sickness, which is manageable and subsides around the end of the first trimester, hyperemesis gravidarum can persist beyond that and significantly affect a woman's quality of life and nutritional intake. The severity of these symptoms can result in the need for hospitalization and medical intervention to stabilize the patient, often including intravenous fluids and medications to control nausea. This distinguishes hyperemesis gravidarum from lesser forms of nausea and vomiting during pregnancy, where symptoms are less severe and typically do not require such intensive management.
