Monitoring Rehydration

Dehydration in children occurs when they lose more fluids than they take in. Children dehydrate faster than adults because they have more water in their bodies and burn energy more quickly.When children are active, they are at increased risk of becoming dehydrated as they may forget to drink enough water.

Water is essential for all bodily functions, including blood flow, oxygen delivery, brain function, digestion, and waste removal. Without enough water, your child’s body can’t function properly, leading to dehydration symptoms, such as thirst, dry mouth, and darker or less frequent urine.

How to Rehydrate a Child

At Home

Give your child oral rehydration solutions (ORS) likePedialyteto replace lost fluids, sugars, and salts for mild dehydration. If your child is experiencing vomiting, give them small sips or 1 teaspoon (5 milliliters) of ORS every five to 10 minutes.Pause for 10 to 15 minutes if vomiting continues, then try again. Offer 1 tablespoon of fluids less often for diarrhea.

Rehydration Tips

At a Medical Facility

Healthcare providers will assess the severity of dehydration through vital signs, weight, exams, blood tests, and urine tests. If your child can drink and hold down fluids, they may first try ORS or ReSoMal (rehydration solution for malnourished.

ReSoMalReSoMal has lower sodium and higher potassium, magnesium, and zinc than standard ORS. Providers typically give it at medical facilities to ensure proper dosage and monitoring.

ReSoMal

ReSoMal has lower sodium and higher potassium, magnesium, and zinc than standard ORS. Providers typically give it at medical facilities to ensure proper dosage and monitoring.

If your child has moderate or severe dehydration or cannot keep fluids down, the team might giveintravenous (IV) fluidsto restore hydration quickly. Sometimes, they use anasogastric(NG) tube, which delivers fluids from the nose to the stomach.

Monitoring a Child During the Rehydration Stages

At a medical facility, the healthcare team will look for signs that your child is getting better, such as having more energy, peeing more often, showing stable vital signs, having normal blood test results, and improving weight.

At home, watch for these signs of improvement:

Summary

Dehydration can cause a dry mouth, dark urine, and less frequent urination. In severe cases, children may become listless, confused, breathe rapidly, or faint, needing emergency care. To prevent dehydration, encourage regular fluid intake, especially during play. For sick children, start with oral rehydration solutions (ORS). Severe cases might require IV fluids.
