Is this your child's symptom?
- Sudden increase in the number and looseness of stools
- Diarrhea means 3 or more watery or very loose stools. Reason: 1 or 2 loose stools can be normal with changes in diet.
Causes of Acute Diarrhea
- Virus (such as Rotavirus). An infection of the intestines from a virus is the most common cause.
- Bacteria (such as Salmonella). Less common cause. Diarrhea often contains streaks of blood.
- Food Poisoning. This causes rapid vomiting and diarrhea within hours after eating the bad food. It is caused by toxins from germs growing in foods left out too long. Most often, symptoms go away in less than 24 hours. It often can be treated at home without the need for medical care.
- Giardia (a parasite). More likely in child care center outbreaks.
- Traveler's Diarrhea. Caused by germs in food or drink. Suspect this if it follows recent foreign travel.
- Antibiotic Diarrhea. Many antibiotics cause mild diarrhea. This is not an allergic reaction. Keep giving the antibiotic. Call your doctor if any serious symptoms occur.
- Serious Causes. Most bacterial diarrhea goes away on its own. A few can cause a severe large bowel infection (such as Shigella colitis). C. difficile is a serious cause that can occur after being on strong antibiotics.
- Serious Complication: Dehydration. This is the health problem where the body has lost too much fluid. (See below for more on this).
Causes of Recurrent Diarrhea
- Cow's Milk Allergy. Can cause loose, slimy stools in babies. Can be blood-streaked. Starts within the first 2 months of life. Need to avoid cow's milk formulas.
- Toddler's Diarrhea. Toddlers who pass 3 to 6 sloppy stools per day. Stools may run out of the diaper. Symptoms begin at age 1. Symptoms resolve at age 3 or 4, after toilet trained. Harmless and no impact on growth. Fruit juice makes it worse. The cause is rapid transit time from stomach to anus. May develop irritable bowel syndrome (IBS) in adult years.
- Lactose Intolerance. Lactose is the sugar in milk. Many people cannot absorb lactose. The gut bacteria convert the lactose to gas. The main symptoms are a lot of gas, loose stools and stomach bloating. Onset usually at age 4 or 5. This most often runs in the family (genetic).
- Mild: 3-5 watery stools per day
- Moderate: 6-9 watery stools per day
- Severe: 10 or more watery stools per day
- The main risk of diarrhea is dehydration.
- Loose or runny stools do not cause dehydration.
- Frequent, watery stools can cause dehydration.
Dehydration: How to Know
- Dehydration means that the body has lost too much fluid. This can happen with vomiting and/or diarrhea. A weight loss of more than 3% is needed. Mild diarrhea or mild vomiting does not cause this. Neither does a small decrease in fluid intake.
- Dehydration is the most important problem caused by diarrhea. Dehydration is a reason to see your doctor right away.
- These are signs of dehydration:
- Decreased urine (no urine in more than 8 hours) happens early in dehydration. So does a dark yellow color. If the urine is light straw colored, your child is not dehydrated.
- Dry tongue and inside of the mouth. Dry lips are not helpful.
- Dry eyes with decreased or absent tears
- In babies, a depressed or sunken soft spot
- Slow blood refill test: longer than 2 seconds. First, press on the thumbnail and make it pale. Then let go. Count the seconds it takes for the nail to turn pink again. Ask your doctor to teach you how to do this test.
- Fussy, tired out or acting ill. If your child is alert, happy and playful, he or she is not dehydrated.
- A child with severe dehydration becomes too weak to stand. They can also be very dizzy when trying to stand.
Diarrhea in Breastfed Babies: How to Tell
- Diarrhea in a breastfed baby is sometimes hard to tell.
- Normal breastfed stools are loose (often runny and seedy). Stools are yellow, but sometimes can be green. The green color is from bile. Runny stools can even be bordered by a water ring. These are all normal stools.
- Breastfed babies often pass more than 6 stools per day. Until 2 months of age, they may pass a stool after each feeding. But, if stools suddenly increase in number and looseness, suspect diarrhea. If it lasts for 3 or more stools, the baby has diarrhea.
- If the stools contain mucus, blood or smell bad, this points to diarrhea.
- Other clues to diarrhea are poor eating, acting sick, or a fever.
Diarrhea in Formula-Fed Infants: How to Tell
- Formula-fed babies pass 1 to 8 stools per day during the first week. Then it starts to slow down to 1 to 4 per day. This lasts until 2 months of age.
- The stools are yellow in color and thick like peanut butter.
- Suspect diarrhea if the stools suddenly increase in number or looseness. If it lasts for 3 or more stools, the baby has diarrhea.
- If the stools contain mucus, blood, or smells bad, this points to diarrhea.
- Other clues to diarrhea are poor eating, acting sick or a fever.
- After 2 months of age, most babies pass 1 or 2 stools per day. They can also pass 1 every other day. They no longer appear to have mild diarrhea.

Care Advice for Diarrhea
Treatment for Mild Diarrhea
- What You Should Know About Diarrhea:
- Most diarrhea is caused by a virus.
- Bacterial infections as a cause of diarrhea are not common.
- Diarrhea is the body's way of getting rid of the germs.
- The main risk of diarrhea is dehydration. Dehydration means the body has lost too much fluid.
- Most children with diarrhea don't need to see their doctor.
- Note: 1 or 2 loose stools can be normal with changes in diet. Diarrheal illness means 3 or more watery stools per day.
- Here are some tips on how to keep ahead of the fluid losses.
- Mild Diarrhea:
- Most kids with diarrhea can eat a normal diet.
- Drink more fluids to prevent dehydration. Formula, breastmilk and/or regular milk are good choices for diarrhea.
- Do not use fruit juices or full-strength sports drinks. Reason: they can make diarrhea worse.
- Solid foods: eat more starchy foods (such as cereal, crackers, rice, pasta). Reason: they are easy to digest.
- Formula-Fed Babies with Frequent, Watery Diarrhea:
- Keep giving formula but feed more often. Offer as much formula as your child will take.
- Mix formula the normal way. Reason: the formula contains plenty of water and doesn't need more.
- Solid foods: if on baby foods, continue them. Cereals are best.
- Breastfed Babies with Frequent, Watery Diarrhea:
- Give your baby breastmilk more often.
- Also, give extra fluid if breast milk isn't keeping up with the fluid losses. You can use formula or ORS (Pedialyte).
- Solid foods: if on baby foods, continue them. Cereals are best.
- Older Children (age more than 1 year old) with Frequent, Watery Diarrhea:
- Offer as much fluid as your child will drink. If also eating solid foods, water is fine. So is half-strength Gatorade or half-strength apple juice.
- If won't eat solid foods, give milk or formula as the fluid.
- Caution: do not use most fruit juices, full-strength sports drinks or soft drinks. Reason: they can make diarrhea worse.
- Solid foods: starchy foods are easy to digest and best. Offer cereals, bread, crackers, rice, pasta or mashed potatoes. Pretzels or salty crackers will help add some salt to meals. Some salt is good.
- Oral Rehydration Solutions (ORS), such as Pedialyte:
- ORS is a special fluid that can help your child stay hydrated. You can use Pedialyte or the store brand. It can be bought in food stores or drug stores.
- When to use: start ORS for frequent, watery diarrhea if you think your child is getting dehydrated. That means passing less urine than normal. Increase fluids using ORS. Continue giving breastmilk, formula or regular milk.
- Amount: for babies, give 2-4 ounces (60-120 mL) of ORS after every large watery stool.
- For children over 1 year old, give 4-8 ounces (120-240 mL) of ORS after every large watery stool. Children rarely need ORS after age 3.
- Caution: do not give ORS as the only fluid for more than 6 hours. Reason: your child will need calories and cry in hunger.
- Probiotics are healthy bacteria (such as Lactobacilli). They can replace harmful bacteria in the gut (stomach).
- Probiotics may be helpful in reducing the number of diarrhea stools.
- Age over 12 months old: yogurt is the easiest source of probiotics. Give 2 to 6 ounces (60 to 180 mL) of yogurt. Do this twice daily. Note: today, almost all yogurts are "active culture".
- Probiotic supplements can also be bought in health food stores.
- Fever Medicine:
- For fevers above 102° F (39° C), give an acetaminophen product (such as Tylenol).
- Another choice is an ibuprofen product (such as Advil).
- Note: fevers less than 102° F (39° C) are important for fighting infections.
- For all fevers: keep your child well hydrated. Give lots of cold fluids.
- Diaper Rash - Prevention:
- Wash buttocks after each stool to prevent a bad diaper rash.
- To protect the skin, use an ointment (such as Vaseline or Desitin). Put it on the skin around the anus.
- Return to School:
- Your child can go back to school after the stools are formed.
- The fever should also be gone.
- The older child can go back if the diarrhea is mild.
- The toilet trained child also needs to have good control over loose stools.
- What to Expect:
- Viral diarrhea lasts 5-14 days.
- Severe diarrhea only occurs on the first 1 or 2 days. But, loose stools can last for 1 to 2 weeks.
- Call Your Doctor If:
- Blood in the diarrhea
- Dehydration suspected (no urine in over 8 hours, dark urine, very dry mouth, and no tears)
- Diarrhea lasts over 2 weeks
- You think your child needs to be seen
- Your child becomes worse
