Chronic diarrhea of infancy, also called toddler's diarrhea, is a common condition typically affecting children between ages 6–30 months, usually resolving by age 4.[1] Symptoms include multiple loose bowel movements per day, sometimes with undigested food visible; normal growth with no evidence of malnutrition; and no evidence blood in the stool or infection. The condition may be related to irritable bowel syndrome.[1]



Differential diagnoses[edit]

Before a diagnosis of toddler's diarrhea is made, the following conditions should be ruled out:[2]


Treatment is primarily through diet. Dietary fiber and fat can be increased and fluid intake, especially fruit juice intake, decreased. With these considerations, the patient should consume a normal balanced diet to avoid malnutrition or growth restriction.[1] Medications such as loperamide should not be used.[1][2] Studies have shown that certain probiotic preparations such as Lactobacillus rhamnosus (a bacterium) and Saccharomyces boulardii (a yeast) may be effective at reducing symptoms.[3][4]
