Diarrhea in Children- Management and Treatment

Diarrhea in Children- Management and Treatment

Published on Wednesday, January 18, 2023 by Author Name

If you are a parent, I am sure you have dealt with diarrhea in your child at least once in your parenting role. 

Globally, diarrheal diseases are a serious public health concern accounting for nearly 2,200 deaths per day in children under the age of 5. The majority of these deaths are related to poor sanitation, unsafe water conditions, and inadequate hygiene. According to the Centers for Disease Control and Prevention, the rotavirus accounts for 40% of all diarrhea-related hospitalizations in children under the age of 5. In the United States, statistics show that the incidence of chronic diarrhea is less than 0.2 episodes per child/year, but children in social settings such as daycares and schools may be at a higher risk of contracting diarrhea.

Let’s define diarrhea.

First, it is important to know your child’s bowel movements at baseline. A change in consistency and frequency can be one way to gauge diarrhea. Another helpful tool is the Bristol stool chart. Type 6 and type 7 stools are classified as diarrhea. Chronic diarrhea is diarrhea that lasts longer than 4 weeks.

What can generally cause my child to have diarrhea?

  • Lactose intolerance
  • Bacterial or viral infections
  • Irritable Bowel Syndrome (IBS)
  • Post-infectious IBS (PI-IBS)
  • Parasites
  • Inflammatory bowel disease (IBD)
  • Antibiotic use
  • Certain medication use
  • Fat malabsorption
  • Small intestinal bacterial overgrowth (SIBO)
  • Celiac disease 

What tips can I use to help treat and manage my child’s diarrhea?

As long as the diarrhea is not associated with vomiting and your child does not appear to be dehydrated, your child likely does not need a change in diet or added electrolytes.

If your child has diarrhea paired with vomiting, it may be a good idea to focus on fluids with electrolytes while vomiting. Once the vomiting has stopped you may slowly return your child to a regular diet. It may be helpful to start first with a bland diet to help with the tolerance of foods.

What are signs that my child may be dehydrated?

Urinating less than normal (no wet diapers for 3 hours or more), dry mouth, no tears when crying, sunken eyes or cheeks, dark-colored urine, and complaining of thirst.

How do I know if I am giving my child enough fluid while they are having diarrhea?

If your child is experiencing diarrhea without vomiting and can keep liquids down, the following is recommended:

For babies: 2-4 oz of oral rehydration solution after every large bowel movement

For children > 1-year-old: 4-8 oz of oral rehydration solution after every large bowel movement

What is an oral rehydration solution (ORS)?

ORS is designed to replace water and electrolytes during diarrhea. They are used to prevent dehydration, rehydrate, and maintain hydration status. You can make your own at home if you choose to not rely on pre-made drinks like Pedialyte or Gatorade. ESPGHAN has recommendations for the composition of ORS, which includes a carbohydrate (glucose) + sodium + potassium. As a side note, many people think that magnesium should also be included.

Here are some examples of ingredients for a homemade ORS from Dartmouth Health:

  1.       1 cup unsweetened orange juice (no pulp), 4 ½ cups water, 8 tsp sugar, ¾ tsp salt
  2.       ½ cup Grape Juice, 3 ½ cups water, ½ tsp salt
  3.       1 cup Apple juice, 3 cups water, ½ tsp salt

This is not medical advice; as always, listen to your parental gut. Advocate for your child’s needs and reach out to your medical provider if you have any additional questions.
