Which condition is characterized by severe vomiting in pregnancy?

Hyperemesis gravidarum is a condition characterized by severe vomiting during pregnancy that goes beyond the typical nausea and vomiting often associated with morning sickness. While many pregnant individuals experience some level of nausea and vomiting, hyperemesis gravidarum can result in significant weight loss, dehydration, electrolyte imbalances, and the need for medical intervention, such as hospitalization or medication. This condition can severely impact the health of both the mother and the fetus if not properly managed.

In contrast, morning sickness typically refers to mild to moderate nausea and vomiting that often occurs in the first trimester and usually resolves as the pregnancy progresses. It does not lead to the severe complications associated with hyperemesis gravidarum, such as malnutrition and dehydration. Other conditions like preeclampsia and gestational hypertension are related to high blood pressure and do not primarily feature severe vomiting as a symptom. Understanding these distinctions is crucial for proper diagnosis and treatment in obstetric care.
