Hyperemesis gravidarum is a severe form of nausea and vomiting that occurs during pregnancy. Unlike typical morning sickness, it can lead to dehydration, weight loss, and nutritional deficiencies. Affected individuals may struggle to keep food and fluids down, which can impact their overall health and the health of the developing fetus. This condition usually occurs in the first trimester but can persist throughout the pregnancy. Treatment often involves hydration, dietary changes, and sometimes medication to manage symptoms. Early intervention is crucial to prevent complications for both the pregnant person and the baby.
