Dehydration in toddlers may happen in the summers or during bouts of infection. The avenues of water loss are aplenty from excessive sweating to diarrhea and vomiting. But parents can address dehydration and conveniently prevent it too. Read on as MomJunction doles out essential information on dehydration in toddlers.

What Is Dehydration?

Dehydration is the condition where the body loses more water than it receives. It creates a scarcity of water for essential body functions eventually disrupting normal metabolic processes. Toddlers are the most susceptible group to dehydrate as their smaller bodies hold lesser fluid reserves (1).

What Causes Dehydration In Toddlers?

Toddlers can lose fluids through several ways, thus resulting in dehydration:

  1. Diarrhea is the leading cause of water loss among toddlers (2). The condition arises due to loose stools caused by viral, bacterial, or parasitic infection, and even food allergy. The condition causes a rapid water loss from the toddler’s body, thus, leading to dehydration.
  1. Vomiting rapidly depletes the body’s fluid reserves, just as diarrhea does.
  1. The high body temperature during a fever makes the body lose water quickly, especially when the toddler sweats.
  1. High heat and humidity lead to excessive sweating, which can lead to dehydration and heat stroke (3). Toddlers who play a lot in the outdoors can be prone to this form of dehydration. Your toddler may not be able to tell you about dehydration but their body gives you enough signals.

What Are The Signs Of Dehydration?

Look out for these symptoms (4):

  1. Dry mouth is the earliest sign of dehydration in toddlers. You notice lesser salivation , and the mouth appears sticky with dry lips.
  1. There is no urination for six to eight hours or very dark and concentrated urine.
  1. There are fewer tears than normal when the toddler cries.
  1. The toddler’s eyes appear sunken into the sockets.
  1. The toddler’s soft spot at the top of the head (called fontanelle) appears sunken.
  1. The toddler would be disinterested in any activity. He will have lower levels of concentration and would act fussy when coaxed to do something.
  2. Dehydration due to an infective cause will produce soft or watery stools even if the child is dehydrated.

When dehydration is only due to vomiting or overheating, then the bowel movement will be infrequent, and stools might be harder.

If you suspect dehydration and these symptoms are present then contact your pediatrician or health care provider.

When To Rush To A Doctor?

Take the toddler to a doctor or emergency unitwhen you see the following signs:

  • Drowsiness and semi-unconsciousness
  • Repeated vomiting and/ or diarrhea
  • Urination happens only once or twice in 24 hours
  • The toddler is unable to keep any fluids down

Vomiting and diarrhea cause rapid fluid loss while infrequent urination indicates that dehydration has begun already. This is when the toddler must be taken to a doctor for diagnosis.

How Is Dehydration Diagnosed?

Pediatricians look for symptoms mentioned earlier as dehydration is mostly a clinical diagnosis.  They might proceed to the following diagnostic tests to aid the diagnosis and treatment process:

  • Blood tests helps understand the levels of sodium and potassium in the blood that can be abnormal is the child is very dehydrated.
  • Urine test checks for concentrated urine, which is a tell-tale sign of dehydration and an indicator of low fluid levels in the body.

How Is Dehydration In Toddlers Treated?

Replenishing the lost fluids is the only treatment for dehydration, but treating the underlying cause is also important. Here is how dehydration is treated (5):

1. Oral rehydration

Oral rehydration salts, better known as ORS, are over-the-counter medicine for rehydration of toddlers. You can either purchase a readymade rehydration drink or buy an ORS powder to dissolve in drinking water. A single pouch is usually dissolved in a liter of water but look for manufacturer’s instructions. The next step is the oral rehydration process.

Oral rehydration process

i. Oral rehydration process spans over four hours.

ii. The volume of ORS solution depends on a toddler’s weight. The World Health Organization (WHO) recommends multiplying the toddler’s weight in kilograms with 75 to arrive at ORS volume in milliliters (6).

iii. For example, if the toddler weighs 10kg, you will need to give him 750ml of ORS solution in four hours.

iv. Give one or two teaspoons (5 or 10ml) of ORS solution with a spoon or oral syringe every few minutes.

v. After four hours, assess the toddler’s condition.

If the toddler’s pediatrician suggests a higher volume of ORS, then follow the doctor’s recommendation. Repeat the rehydration procedure if the toddler is still very dehydrated. It would be best to give small volumes of fluid frequently especially in a child that is vomiting.

2. Intravenous rehydration

Extreme cases of dehydration have to be dealt with an intravenous (IV) fluid infusion. It is required when the toddler becomes semi-conscious, unresponsive, and develops severe lethargy. IV fluids are administered only at a hospital under the doctor’s supervision.

3. Antibiotic, antiviral, and analgesic medication

Antibiotics and antiviral medicines is generally not needed.  In some cases they might be used to treat the underlying infection. Fever is managed using medications such as ibuprofen and acetaminophen. These medicines are administered as per the doctor’s prescription.

Oral rehydration along with some medicines is perhaps all you need to cure a preschooler’s dehydration. But the care does not end there. You could also use a few home remedies.

What Are The Home Remedies For Dehydration?

Follow these steps at home to relieve the toddler’s dehydration:

  • Feed foods that hydrate: Make the toddler eat fruits with high water content, such as watermelon and bananas. You can also give fresh and tender coconut water. Feed diluted fruit purees, vegetable or chicken broth, and preparations with high water content such as khichdi. Yogurt is also a good option against dehydration.
  • Give plenty of water: Give sips of water at regular intervals and increase the frequency when the weather is hot or humid.
  • You can continue breastfeeding if your child has diarrhea.

Do not give fruit juice and commercial sports drinks as they contain high sugar and sodium, which can increase dehydration levels (7). If the toddler suffers from diarrhea, then cut down on formula or cow milk since it can aggravate loose stools. You may also consult a pediatrician or a pediatric dietician to know what foods suit your toddler. Once the toddler is back to good health, feed them the usual way.

How To Prevent Dehydration In Toddlers?

Preventing dehydration involves mitigating the loss of surplus fluids from the body. Here is what you should do:

  • Keep the toddler hydrated. Make sure they get adequate fluids in accordance with their lifestyle and weather. Toddlers who spend a lot of time outdoors need more water than those who play indoors. Fluid loss through sweating is higher in humid conditions; therefore the toddler must have regular sips of water. You can add mint leaves or a bit of lime juice to the water if they don’t like drinking water..
  • Prevent infections of the gastrointestinal tract as they can lead to diarrhea and vomiting. Maintain hygiene and teach your toddler healthy habits such as washing hands before and after meals and when coming back home from outside.
  • Experts recommend dressing your toddler in light weight, light-colored, and loose-fitting clothes in hot and humid weather (8). Heat dissipation is better in such outfits, thus reducing the possibility of overheating and dehydration.

Having an adequate fluid intake is the key to prevent dehydration in toddlers. Remember, the more active your toddler, the more water they will need. Staying vigilant helps detect dehydration early. Rehydration and some care will bring back the preschooler to normal.
