In infants, which sign is indicative of dehydration?

In infants, signs of dehydration can manifest in various ways, and one of the most telling indicators is the presence of sunken eyes and cracked lips. This occurs because dehydration causes a reduction in skin turgor and moisture, leading to changes in the appearance of the eyes and mouth. Sunken eyes suggest that the body is not retaining enough fluid, while cracked lips can indicate that the mucous membranes are drying out due to insufficient hydration.

Other signs of dehydration may include dry mouth, decreased urine output, or lethargy. Recognizing these signs early is crucial in ensuring that infants receive appropriate care and hydration, as dehydration can lead to more severe complications if not addressed promptly.

While warm skin temperature and high energy levels do not suggest dehydration, frequent urination typically indicates proper hydration levels rather than a deficiency. In contrast, a dehydrated infant would likely exhibit reduced urine output as the body tries to conserve fluids. Therefore, the combination of sunken eyes and cracked lips serves as a clear and concise sign of dehydration in infants.
