In pregnancy, the majority of women experience at least some nausea and vomiting. For many women, these symptoms are mild and self-limiting and resolve by the second trimester. A minority of women experience severe symptoms of hyperemesis gravidarum with persistent vomiting, weight loss, and electrolyte derangements. The diagnosis of hyperemesis gravidarum is based on clinical history and exclusion of other etiologies of nausea and vomiting. First-line pharmacologic treatment is with pyridoxine and doxylamine. Other medical treatments include metoclopramide, phenothiazines, antacids, and ondansetron. In refractory cases, corticosteroids and enteral or parenteral nutrition may be considered.
