What is the recommended approach for treating an infant with acute diarrhea?

Rehydration within 4-6 hours is a critical and recommended approach for treating an infant with acute diarrhea. Acute diarrhea in infants can lead to significant fluid loss and the risk of dehydration, which can be particularly dangerous in younger children due to their smaller body size and limited fluid reserves. Rapid rehydration helps to restore fluid and electrolyte balance, which is essential for the infant’s health.

Typically, oral rehydration solutions (ORS) are recommended for this purpose, as they contain the right balance of electrolytes and sugars to facilitate absorption. Addressing hydration needs promptly can prevent further complications associated with dehydration, such as electrolyte imbalances and impaired kidney function.

In contrast, introducing solid foods may burden the infant’s digestive system during a time when it is compromised. Starting a low-fat diet is not generally advisable in cases of acute diarrhea, as fat is often important for recovery and nutrition in infants. While probiotics can be beneficial in some contexts, initiating probiotic therapy does not directly address the immediate need for rehydration and should not replace fluid replacement strategies in acute situations. Thus, rehydration remains the priority in managing acute diarrhea in infants.
