What is the most appropriate fluid to offer a toddler recovering from dehydration due to diarrhea?

An oral rehydration solution is specifically formulated to replace lost fluids and electrolytes due to dehydration, making it the most appropriate choice for a toddler recovering from diarrhea. These solutions typically contain a precise balance of salts and sugars, which enhances absorption in the intestines and encourages rehydration effectively. This can help prevent further complications associated with dehydration, such as electrolyte imbalances.

On the other hand, fruit juice, while it may provide some hydration, typically has a high sugar content and low electrolyte concentration which could exacerbate diarrhea. Water alone does not contain the necessary electrolytes to effectively rehydrate a child suffering from dehydration due to diarrhea. Soda often contains caffeine and high sugar levels, which are not suitable for rehydration and can potentially worsen gastrointestinal symptoms. Therefore, an oral rehydration solution is the most beneficial and medically appropriate option for rehydrating a toddler in this situation.
