The age group that is at high risk for fluid and electrolyte imbalance from gastroenteritis is neonates. This vulnerability is due to several physiological factors. Neonates, or newborns, have a higher body water content compared to older children and adults; nearly 75-78% of their body weight is made up of water. This means they have a smaller reserve to draw upon when they lose fluids due to conditions like gastroenteritis.

Additionally, neonates have immature renal function, limiting their ability to concentrate urine and retain water or electrolytes in cases of dehydration. Their ability to communicate thirst is also not developed, making it difficult for them to compensate for fluid loss. All of these aspects contribute to a greater risk of both dehydration and electrolyte imbalances in this age group when faced with gastroenteritis.

While preschool children do face risks related to gastroenteritis, the combination of immature organ function and higher fluid turnover in neonates places them at an even higher vulnerability.
