Why does juice give my kid diarrhea?

If your child tends to get diarrhea after drinking juice, you’re not alone. Many parents report their kids getting loose stools from drinking fruit juices or juice drinks. This article explores the reasons why juice may cause diarrhea in children and offers tips to help prevent it.

Too Much Sugary Juice Can Cause Diarrhea

One of the main reasons juice gives kids diarrhea is the high sugar content. Many juices, especially fruit juices, contain a lot of natural sugars from the fruits. Some juices also have added sugars to make them taste sweeter. Consuming too much sugary juice in a short period can draw fluid into the intestines, causing watery stools.

Beverage	Grams of Sugar per 8 oz Serving
Apple Juice	24g
Grape Juice	36g
Fruit Punch	40g

As you can see from the table above, even healthy fruit juices are packed with naturally occurring sugars. Drinking too much can overwhelm a child’s digestive system and pull fluid into the bowel, resulting in diarrhea.

The Wrong Juices Can Irritate the Stomach and Intestines

Certain juices contain ingredients that can irritate a child’s gastrointestinal tract, increasing the risk of diarrhea. These may include:

• Citrus juices – Citrus fruits like oranges, grapefruits, and limes contain organic acids that can irritate the stomach lining.
• Prune juice – Prune juice contains sorbitol, a natural laxative that can stimulate bowel movements.
• Vegetable juices – Carrot, tomato, and green juices are often highly acidic which can disrupt digestion.
• Juices with added sweeteners – Sweeteners like high fructose corn syrup can draw excess fluid into the intestines.

If your child’s stools become loose after drinking any of these kinds of juices, irritation from the ingredients is likely the culprit.

Kids May Be Intolerant to Certain Juice Ingredients

Some children may have sensitivities or intolerances to certain components in juice that can lead to diarrhea, such as:

• Fructose – This natural sugar in juice can be difficult for some kids to absorb properly.
• Sorbitol – Found in apple, pear, prune, and stone fruit juices. It pulls water into the intestines.
• Caffeine – Energy drinks and soda with caffeine can stimulate the bowels.
• Artificial sweeteners – Sweeteners like aspartame can cause digestive issues in sensitive kids.

Keep a food diary to identify if any specific ingredients tend to give your child loose stools. Avoiding juices with those ingredients may help prevent diarrhea.

Too Much Juice Can Disrupt Digestion

Drinking large amounts of juice, even 100% fruit juice, may disrupt your child’s digestion process and lead to diarrhea for a few reasons:

• It can reduce appetite and lead to inadequate fiber/nutrient intake from solid foods.
• The sugary content requires less digestion so food moves through the intestines faster.
• Juice doesn’t have the soluble fiber of whole fruits and vegetables that adds bulk to stools.

Try limiting juice to 4-6 oz per day and focusing more on solids and water to support healthy digestion.

Contaminated Juice Can Cause Diarrhea

On rare occasions, drinking contaminated juice can result in diarrhea symptoms. Juice contamination can occur when:

• Fresh juice isn’t pasteurized properly and contains pathogens from produce.
• Pre-packaged juice is incorrectly processed allowing bacterial growth.
• Open juice containers are left out allowing mold or bacteria to develop.
• Unpasteurized apple cider is contaminated with E. coli.

To avoid contaminated juice, buy pasteurized juices from reputable brands, refrigerate after opening, and discard after 3-5 days. Wash produce thoroughly when making fresh juice at home.

When to See a Doctor

Occasional loose stools from drinking too much juice should resolve on their own. However, see a doctor if your child has:

• Severe cramping or abdominal pain
• Blood or mucus in the stool
• Diarrhea lasting more than 2 days
• Signs of dehydration like dry mouth, infrequent urination, or weakness

These may indicate a more serious condition like a bowel infection or chronic diarrhea disorder.

Tips to Prevent Juice-Related Diarrhea

You can take steps to reduce the likelihood of juice giving your child diarrhea:

• Limit juice to 4-6 oz per day for young kids.
• Offer whole fruits and veggies instead of just juice.
• Dilute juice with water 50/50 to reduce sweetness.
• Avoid citrus, prune, and vegetable juices.
• Read labels and pick 100% juice with no added sugar or sweeteners.
• Store opened juice in the fridge and discard after a few days.

Pay attention to how much and what types of juice tend to cause your child issues. Limiting sugary, acidic, and irritating juices can go a long way towards preventing diarrhea.

Provide Adequate Fluids and Probiotics

If your child already has juice-related diarrhea, focus on providing fluids and probiotics to help their digestion get back to normal.

• Give plenty of water, oral rehydration solutions, or diluted juice.
• Stick to the BRAT diet – bananas, rice, applesauce, and toast.
• Give probiotic-rich yogurt or supplements to replenish gut bacteria.
• Avoid milk and sugary juices until stools firm up.

Talk to your pediatrician if diarrhea lasts more than 2 days or your child shows signs of dehydration. Otherwise, staying hydrated and restoring a healthy gut balance should help resolve juice-related diarrhea.

Conclusion

Juice can sometimes cause diarrhea in kids due to its high sugar content, potential to irritate the GI tract, and role in disrupting digestion. By limiting and diluting sugary juice, avoiding specific irritating ingredients, and focusing more on solids and water, you can help reduce the chances of diarrhea. Pay attention to what types of juice tend to affect your child’s stomach and adjust their diet accordingly. With some minor changes to juice habits, your child can still enjoy an occasional small glass without digestive distress.
