How To Know If My Child Is Dehydrated?

Your child loses water every day in the form of sweat, tears, and urine. Under normal circumstances, your child will replace the lost liquids by drinking water and other drinks like juices and soups. When your child's water loss is not replenished, they get dehydrated. This can happen when your child plays in the sun for a long time or suffers from fever, vomiting, or diarrhea. Young children are particularly susceptible to dehydration as their little bodies cannot store much water as the adults do. So, even a small loss can dehydrate her. Your child should drink enough water such that their urine is pale in color. The following are other indicators of dehydration.

Here are the symptoms to look out for when you're wondering if your child is dehydrated.

  • dry mouth and cracked lips
  • no urine for more than 8 hours or dark-coloured urine
  • sunken soft spot on the head
  • no tears while crying
  • dry or cold hands and feet
  • tiredness or low energy levels
  • irritability or confusion


Being out in the hot sun for a prolonged time puts your child at the risk of dehydration. Children don't sweat as much as adults, and their bodies heat up quickly during physical activities. When your child doesn't drink enough water - which most children often forget while playing - they may get dehydrated.

Common illnesses like viral infections can cause your child's food intake to be less than usual. Furthermore, when your child has severe throat pain, they may refuse to eat or drink. This can also lead to dehydration. Repeated vomiting and diarrhea due to stomach flu can deprive your child's fluid reserves too.

Prevention and treatment at home

When your child is having fun in the sun, make sure to offer them water every twenty minutes. It is also a good idea to have a shady place to play instead of directly playing under the sun. In hot summers, let your child play in the water to cool off.

If your child is down with fever, it is important that your child is well hydrated. Include milk, soups, and juice in their diet. Dehydration can occur quickly when your child is suffering from bouts of diarrhea or vomiting. Since they are losing water, you should constantly restore the water supply for their body. Milk and juice are not ideal for tummy troubles as they can aggravate the condition.

If you're breastfeeding your baby, you should continue doing so to keep them hydrated. Formula-fed babies can take their formula in the normal consistency, there is no need to dilute it. Drinks that are high in sugar are a strict no-no because they can make your child's dehydration worse.

For mild to moderate dehydration, the simple yet effective treatment is rehydration in the form of ORS (Oral Rehydration Solutions) that are widely available in the pharmacies to your child. They come in a wide range of flavors, so it is easy to make your child drink them. Remember to follow the instructions on the package.

When to see a doctor?

Though dehydration can be treated at home, some severe cases warrant a visit to the doctor. Here are the symptoms to watch out for:

  • Your child is younger than 6 months
  • Your child is not showing any improvement
  • There is blood in your child's stool or vomit
  • Your child's vomit is green in color
  • Your child refuses any fluids or ORS
  • Your child has had diarrhea for more than 10 days
  • Your child develops a new symptom

When your child is severely dehydrated, they may have a faster heartbeat or breathe rapidly. They may become delirious or unconscious. In such a case, take them to a doctor immediately. During an episode of dehydration, your child is not only losing the water, but they are also losing essential minerals like sodium, potassium, and calcium. These minerals are critical for maintaining fluid balance in the body, so if not treated on time, dehydration can lead to severe complications like brain damage and coma. In some cases, dehydration can be deadly too. So, it is imperative that you keep an eye on your child for any worsening symptoms.

Mild dehydration is inevitable in young children, especially so during hot summer months. But, worry not. With the right amount of fluids and your loving care, they will be up on their feet in no time.
