Which symptom is a hallmark of gastroenteritis?

• A. Dehydration
• B. Hearing loss
• C. Hair loss
• D. Joint swelling

Answer: (A)

Dehydration is the hallmark of gastroenteritis because the condition typically causes rapid loss of fluids and electrolytes through vomiting and diarrhea. That fluid loss leads to a consistent set of signs—dry mouth, decreased urine output, skin turgor changes, sunken eyes or fontanelle in infants, and sometimes rapid heart rate—that clinicians look for to identify gastroenteritis in the setting of acute GI symptoms. The other options—hearing loss, hair loss, and joint swelling—are not characteristic features of gastroenteritis and would point to other conditions or causes.
