Child Diarrhea: ORS Recipe, Zinc & Danger Signs
Open this article in the interactive app
Diarrhea — loose, watery stools — is one of the biggest killers of children under five worldwide. The diarrhea itself is rarely fatal. What kills is dehydration: the rapid loss of water and salts from the body. A child can go from playful to dangerously dehydrated in a single day. The good news: dehydration is preventable and treatable at home with two cheap, simple tools — ORS and zinc.
What does it mean?
Diarrhea — loose, watery stools — is one of the biggest killers of children under five worldwide. The diarrhea itself is rarely fatal. What kills is dehydration: the rapid loss of water and salts from the body. A child can go from playful to dangerously dehydrated in a single day. The good news: dehydration is preventable and treatable at home with two cheap, simple tools — ORS and zinc.
Common causes
- ORS is one of the most successful treatments in medical history.
The WHO/UNICEF-recommended low-osmolarity ORS — with reduced salt and glucose — reduces the need for IV fluids and shortens the diarrhea episode (WHO/UNICEF joint statement, via PMC). - Correct ORS recipe:
dissolve one full sachet in one litre of clean drinking water (boiled and cooled is best). Mix until clear. Discard unused solution after 24 hours and never boil the prepared solution (WHO diarrhoeal disease fact sheet). - How much to give:
give small, frequent sips (about a spoonful every 1–2 minutes). After each loose stool, give roughly 50–100 ml (¼–½ cup) for children under 2 years, and 100–200 ml for children 2–10 years, and as much as wanted for older children (WHO IMCI Chart Booklet). If the child vomits, wait 10 minutes, then restart with smaller sips. - Zinc for 10–14 days.
WHO and UNICEF recommend zinc supplementation for 10–14 days alongside ORS: it reduces the duration and severity of the episode and lowers the chance of another diarrhea episode in the next 2–3 months (WHO/UNICEF joint statement). Ask your doctor or pharmacist for the correct dose for your child's age. - Keep feeding — do not starve the child.
Continue breastfeeding and normal feeding during diarrhea. Withholding food weakens the child and slows recovery. A Pakistani study found most mothers already know ORS prevents dehydration — but myths about "resting the stomach" still cost lives (JPMA study, Children's Hospital Lahore). - Rotavirus vaccine protects.
Pakistan's EPI gives rotavirus vaccine at 6 and 10 weeks — it protects against the most common cause of severe infant diarrhea.
When to worry
Seek urgent medical care
Take the child to a hospital immediately if you see any of these danger signs:
Prevention & practical tips
- Start ORS at the first loose stool. Do not wait for "real" dehydration. One sachet + one litre clean water, sipped frequently.
- Give zinc for 10–14 days — even after the diarrhea stops. Get the age-appropriate dose from your doctor or pharmacist.
- Continue breastfeeding and feeding. Offer food more often in small amounts. After the illness, give one extra meal daily for 1–2 weeks to catch up.
- Offer extra fluids. Breastmilk, clean water, soup, rice water — alongside ORS. Check your child's daily water needs so you know how much to aim for.
- Hygiene breaks the cycle. Wash hands with soap after toilet and before feeding; boil drinking water; dispose of the child's stool safely.
- Watch, don't just wait. Check the child every few hours using the danger signs below.
FAQs
Dissolve one full sachet in one litre of clean (preferably boiled, cooled) water. Never use half a sachet in half a litre "by guess" — the salt-sugar balance must be exact. Too much salt is dangerous; too little doesn't work.
Only if no ORS sachets are available, and the recipe must be exact — this is error-prone. Keep ORS sachets at home; they cost almost nothing. Ask your doctor about homemade recipes only as a last resort.
No. Continue breastfeeding and feeding — starving the child makes things worse, not better.
Wait 10 minutes, then give tiny sips (a spoonful every 1–2 minutes). Small and frequent beats large and rare.
Usually no. Most childhood diarrhea is viral; antibiotics don't help and can harm. Only a doctor should decide — never start them yourself.
For 10–14 days, even after the stools become normal. It protects against the next episode too. Ask your doctor/pharmacist for the right dose for your child's age.
