In acute gastroenteritis, clinicians must assess dehydration severity through history (thirst, urine output) and physical examination (dry tongue), classify it as mild, moderate, or severe, and manage accordingly with oral rehydration for mild cases and IV fluids for severe dehydration; viral etiology is most common and does not require antibiotics, while bacterial infections (indicated by blood in stools) need antibiotic coverage including gram-negative and anaerobic organisms, and loperamide should be avoided as it can worsen outcomes.
