Which statement best describes the use of enteral nutrition support in hyperemesis gravidarum?

• A. Postpyloric placement requires radiation exposure; unacceptable during pregnancy
• B. Concentrated, hypertonic formulas maximize nutrient delivery in small volume
• C. Successful use has been reported and a trial of EN prior to PN is appropriate
• D. Randomized trials show EN superior to PN in infectious complications

Answer: (C)

The main idea here is that enteral nutrition is preferred in hyperemesis gravidarum when the gut can tolerate it, and a trial of EN should be attempted before moving to parenteral nutrition. EN supports gut integrity, reduces the risk of catheter-related infections and other PN-associated complications, and can be started with small, easily tolerated feeds that are advanced as tolerated. There are reported cases of successful EN use in hyperemesis gravidarum, so starting enteral feeding and evaluating tolerance before escalating to PN is a reasonable and often effective approach. Postpyloric feeding is not an absolute barrier during pregnancy, and feeds can frequently be given via a stomach (nasogastric/orogastric) route with careful monitoring; hypertonic, concentrated formulas are typically not favored in HG because they can worsen nausea and intolerance. While EN generally has fewer infectious complications than PN, the key takeaway for this scenario is that EN should be tried first when possible, with PN reserved for when EN is not tolerated or insufficient.
