What symptom may indicate dehydration in pediatric patients?

In pediatric patients, dry oral mucous membranes are a clear indicator of dehydration. When a child is dehydrated, their body has reduced fluid levels which can result in less saliva and moisture in the oral cavity. As a consequence, the mucous membranes in the mouth become dry and cracked, which is a visible sign that hydration is not adequate.

Moist oral mucous membranes, on the other hand, indicate proper hydration and are a sign of good health. Increased energy would not be associated with dehydration; typically, a dehydrated child may exhibit lethargy or fatigue. Fluid retention suggests the body has an excess of fluids, which contrasts with the condition of dehydration characterized by a deficiency in body fluids. Therefore, observing dry oral mucous membranes is a significant symptom healthcare providers look for when assessing dehydration in children.
