Why would concentrated enteral solutions not be recommended for nausea/vomiting?

• A. They have a higher fat content, increasing the osmotic load and slowing gastric emptying
• B. They are more expensive
• C. They are lactose-containing
• D. They are not isotonic

Answer: (A)

When nausea or vomiting is present, feeds that move through the stomach with less delay and less osmotic stress are favored. Concentrated enteral solutions tend to have more fat and solutes, which raises the osmolarity of the feed and slows gastric emptying. A higher osmotic load pulls more water into the gut and the delayed emptying keeps the stomach fuller longer, both of which can worsen nausea and vomiting. That’s why these feeds are not recommended in this situation; using diluted, lower-osmolarity formulas helps the stomach empty more readily and reduces triggering symptoms. The other factors—cost, lactose content, or isotonicity—are not the primary drivers here.
