A 5-year-old with acute gastroenteritis is thirsty but tolerates oral fluids well. What is the best initial management?

• A. Oral rehydration solution and continued normal feeding
• B. Rehydration with continued feeding
• C. Ice water only
• D. Gatorade with no feeding

Answer: (A)

When a child with gastroenteritis is mildly dehydrated and can drink, the best first step is oral rehydration using a proper electrolyte solution and to continue normal feeding. Oral rehydration solutions provide the right balance of fluids, electrolytes, and glucose. The glucose helps sodium and water absorption in the gut, which quickly restores hydration while also supporting nutrition and gut healing. Avoid ice water or plain water alone because they don’t replace electrolytes and can fail to correct dehydration adequately. Sports drinks like Gatorade aren’t ideal either due to high sugar and insufficient, appropriately balanced electrolytes for a young child. Intravenous fluids are reserved for dehydration that is moderate to severe or when oral intake isn’t possible.
