What is the common treatment for severe nausea and vomiting in pregnancy?

Severe nausea and vomiting in pregnancy, often referred to as hyperemesis gravidarum, can lead to significant dehydration and nutritional imbalances. The primary goal of treatment is to alleviate these symptoms effectively to protect both the mother and the developing fetus. Medications such as ondansetron, which is categorized as a serotonin 5-HT3 receptor antagonist, are commonly used for this purpose. Ondansetron works by blocking the action of serotonin, a chemical in the brain that can trigger nausea and vomiting. By administering this medication, healthcare providers can help manage the symptoms more effectively than relying solely on non-pharmacological options.

While rest and hydration, counseling, and over-the-counter supplements can play supportive roles in managing mild symptoms of nausea, they may not address the intensity of symptoms experienced in cases of severe nausea and vomiting. In such situations, medications become essential to provide relief and prevent complications associated with prolonged vomiting, such as electrolyte imbalances or inadequate nutritional intake. Therefore, the use of ondansetron as a medication is a standard and effective approach in managing severe cases of nausea and vomiting during pregnancy.
