UNICEF staff are experts in preventing and treating dehydration in children. Learn how to spot the signs and protect your loved ones.
Dehydration occurs when the human body loses excessive amounts of water. If you don't get enough to drink or if your body loses more fluid than it takes in, your body can't perform its normal functions. If fluids aren't replaced, the body becomes dehydrated.
Here are the answers to some Frequently Asked Questions about dehydration based on information provided by the World Health Organization and other sources.
How to know if your child is dehydrated
Dehydration can happen to anyone, but young children are particularly vulnerable because their little bodies can get dehydrated quickly. The most common cause of dehydration in young children is severe diarrhea and vomiting. Exercising vigorously in hot weather without drinking enough water can also lead to dehydration.
Early indications of mild to moderate dehydration include thirst, restlessness and irritability. It is important to note that a child can be dehydrated without feeling thirsty.
Some early warning signs of dehydration in kids
- dry mouth
- cool, moist extremities
- reduced or absent urine flow
- slightly sunken eyes and cheeks
- sunken fontanel (the soft spot on an infant's skull)
- weak pulse
Measuring dehydration: know the indicators
- for babies: no wet diapers for three hours
- for older children: no urination in eight hours
- dark-colored urine
What to give a dehydrated child
Dehydration must be treated by replenishing the body's lost fluids and electrolytes (essential minerals in your blood and body fluids, like sodium, potassium, magnesium, chloride and calcium).
Breastfeeding is the best way to treat dehydration in infants, or formula. Give older children sips of clear liquids. Water is ideal, but you can also try broth, a pre-mixed rehydration solution like Pedialyte or Hydralyte, or a sports drink such as Gatorade diluted with water.
If your child has trouble swallowing liquid, try giving her an ice pop made of frozen water or frozen fruit juice diluted with water to suck on.
Cures and treatments for childhood dehydration
Mild dehydration can be treated by drinking clear liquids such as plain water or sucking on ice pops to help the body replenish the missing fluids it needs to function properly. Start with small sips or teaspoons of liquid and gradually increase fluid intake from there as you see the child can tolerate more.
UNICEF treats children suffering from dehydration with glucose-based Oral Rehydration Salts and oral rehydration therapy. In severe cases, treatment is given intravenously.
How to prevent dehydration in children and toddlers
Always bring a refillable water bottle with you whenever you go out. Make sure to remind your child to drink from it regularly throughout the day.
What to do if a dehydrated toddler won't drink
If your child refuses to drink liquids, it's important not to force them. Instead, try offering them an ice pop made from either frozen water or fruit juice. You can also consider Pedialyte pops as a suitable alternative. Pedialyte pops work too.
Call the doctor if your child or toddler experiences these symptoms
- Increased or constant vomiting for more than a day
- nausea so severe it prevents the child from drinking fluids or sucking on an ice pop
- weight loss
- decreased urine production (for babies: no wet diapers for three hours; for older children: no urination in eight hours)
- dark yellow urine
- extreme sleepiness
- cold and blotchy hands and feet
- no tears when crying
Can a child die of dehydration?
Yes. In severe acute malnutrition, dehydration is caused by untreated diarrhea, which leads to the loss of water and electrolytes (essential minerals the body needs to function properly). Severe acute malnutrition and diarrhea run in a vicious circle, each making the other more severe and more likely to occur.
Summer safety tips for kids
On a hot day, children can become dehydrated even if they stay in the shade. During the summer months, children are likely to sweat more, especially when they're engaging in vigorous physical activity like running around with friends, playing sports and exercising. Make sure your child has a full water bottle when they go out to play, and stress the importance of drinking from it regularly.
UNICEF fights dehydration in children around the world
UNICEF works with partners in more than 100 countries to provide clean, safe water and sanitation to families, so children stay healthy. UNICEF health workers advise parents how to feed their children to prevent dehydration and malnutrition.
UNICEF's lifesaving interventions and programs around the world have helped reduce the number of child deaths by more than 50 percent since 1990.
