Diarrhea is one of the most common reasons parents in Dubai bring their child to a pediatrician — and one of the most common reasons children end up dehydrated quickly, since kids lose fluid faster relative to their body size than adults do. Most cases are mild and settle within a few days with the right home care. This guide covers what typically causes it, how to manage it safely at home, and exactly which signs mean it’s time to get medical help.
What Usually Causes Diarrhea in Children?
- Viral gastroenteritis — by far the most common cause, including rotavirus and norovirus, usually accompanied by vomiting and low-grade fever for 1–3 days.
- Bacterial infections — from contaminated food or water, sometimes with blood in the stool or higher fever, and generally needs medical assessment.
- Antibiotic use — can disrupt normal gut bacteria and cause loose stools during or shortly after a course of antibiotics.
- Food intolerances or new foods — a sudden change in diet, too much fruit juice, or an intolerance (like lactose) can trigger loose stools without infection.
- Toddler’s diarrhea — a common, harmless pattern in well-growing toddlers with no other symptoms, often linked to excess juice or low-fat diets.
Rotavirus remains a leading cause of severe diarrhea and dehydration in young children worldwide, which is why it’s part of the UAE’s routine childhood vaccination schedule — vaccination has significantly reduced severe cases in vaccinated children.
Recognizing Dehydration Early
Because young children can dehydrate within hours of persistent diarrhea or vomiting, catching early signs matters more than treating a “worst case.” Watch for:
- Mild dehydration: slightly dry lips, increased thirst, fewer wet diapers than usual, mild fussiness.
- Moderate dehydration: sunken eyes, dry mouth, noticeably fewer wet diapers (fewer than 4 in 24 hours), lethargy, crying with few or no tears.
- Severe dehydration (emergency): sunken soft spot in infants, very dry mouth, no urination for 8+ hours, extreme drowsiness or difficulty waking, cold or mottled hands and feet, rapid breathing or heart rate.
Safe Home Care for Mild Diarrhea
- Rehydrate with the right fluids. Oral rehydration solution (ORS) — available at Dubai pharmacies — replaces lost salts and sugar far more effectively than water or juice alone, especially with ongoing losses. Offer small, frequent sips rather than large amounts at once, which can trigger vomiting.
- Keep feeding. Continue breastfeeding or formula for infants, and offer your child’s regular diet as tolerated — starvation-style “resting the gut” is outdated advice and can slow recovery.
- Avoid these during acute diarrhea: undiluted fruit juice, sugary sports drinks, and sodas, which can worsen diarrhea due to high sugar content.
- Don’t use over-the-counter anti-diarrheal medication in young children unless specifically directed by your pediatrician — these can be unsafe in this age group and can mask worsening infection.
- Watch diaper/toilet frequency and fluid intake over the next 24 hours as your main guide to whether things are improving or need medical input.
When to See a Pediatrician or Go to the ER
Contact your pediatrician the same day for:
- Diarrhea lasting more than 3 days without improvement
- Blood or mucus in the stool
- Fever above 38.5°C (101.3°F) in a child under 3 months, or a persistent high fever at any age
- Signs of mild-to-moderate dehydration that aren’t improving with home rehydration
- Persistent vomiting alongside diarrhea, making oral rehydration difficult
Go to the emergency room immediately for any signs of severe dehydration listed above, a sunken soft spot in an infant, extreme lethargy or difficulty waking, or a baby under 3 months with diarrhea and fever.
Frequently Asked Questions
How much oral rehydration solution should I give my child?
General guidance is small, frequent amounts — roughly a spoonful every few minutes for infants, working up to more as tolerated — rather than a large volume at once. Exact amounts depend on your child’s age, weight, and degree of fluid loss, so confirm dosing with your pediatrician or pharmacist, especially for infants.
Can I give my toddler milk during diarrhea?
For most children, continuing a normal diet including milk is fine and recommended once mild dehydration has been corrected with ORS. A small subset of children develop temporary lactose intolerance during a gastrointestinal illness — if diarrhea worsens noticeably after dairy, mention this to your pediatrician.
Is it normal for diarrhea to last a week?
Viral diarrhea usually resolves within 5–7 days, though loose stools can occasionally linger a bit longer as the gut recovers. If it extends well beyond a week, is worsening rather than improving, or your child seems unwell, it’s worth a pediatric review to rule out other causes.
Does the rotavirus vaccine mean my child can’t get diarrhea?
No — the rotavirus vaccine significantly reduces the risk of severe rotavirus disease specifically, but children can still get diarrhea from many other viruses, bacteria, or non-infectious causes. It remains one of the most effective tools for preventing the most dangerous, dehydrating episodes.
What’s the fastest way to tell if my child is dehydrated?
Check for tears when crying, moisture inside the mouth, and how recently they last urinated (or how many wet diapers in the last several hours). Dry mouth, no tears, and noticeably reduced urination together are strong signs of at least moderate dehydration and warrant prompt medical attention.
If your child’s diarrhea isn’t improving, or you’re unsure how dehydrated they are, don’t wait it out — book a same-day pediatric visit at myPediaClinic, or read about our rotavirus vaccination program for infants in Dubai.
