The key idea is that the immediate danger in traveler's diarrhea from noninvasive pathogens is dehydration from fluid loss, so the first step is restoring fluids and electrolytes. Rehydration, using oral rehydration solutions when possible or IV fluids if needed, addresses the core problem and prevents complications. Antibiotics can shorten illness but are not the initial management for uncomplicated cases, since hydration alone often suffices and unnecessary antibiotics carry risks. Probiotics have limited proven benefit and aren’t the primary approach, and anti-motility drugs like loperamide aren’t used alone without ensuring hydration and are used cautiously, especially if invasive disease is a concern. In short, rehydration and electrolyte management are the best starting point.
