What are the symptoms of dehydration in children with diarrhea?

The main symptoms of dehydration caused by diarrhea in children are as follows: 1. Decreased urine output: Due to significant loss of body fluids, infants may experience reduced frequency and volume of urination. In severe cases, they may even produce no urine for six hours or longer. 2. Weight loss: When diarrhea causes dehydration, infants lose large amounts of fluid and nutrients, often accompanied by a poor appetite, leading to noticeable weight loss. 3. Fever: In a dehydrated state, the infant's body temperature regulation center may be affected, causing an increase in body temperature. Some children may develop a fever reaching 39°C or higher. 4. Changes in mental status: Dehydration can also affect the infant's mental state, potentially causing symptoms such as irritability, drowsiness, and fatigue. When parents notice these symptoms in their child, they should seek medical attention promptly to prevent the dehydration from worsening.
