Understanding watery bowel movements in children
What causes watery stools in children?
Watery stools in children can be caused by viral infections like rotavirus and norovirus, bacterial infections such as Salmonella and E. coli, food intolerances, or medications like antibiotics that disrupt gut bacteria.
Age-related factors
Age influences the causes of watery stools. Infants may have diarrhoea due to formula intolerance, while toddlers are more prone to infections. Older children may experience digestive issues from stress or conditions like IBS.
Symptoms associated with diarrhoea
In addition to watery stools, symptoms like a high fever, fatigue, chills, loss of appetite and abdominal pain may occur. If your child experiences dehydration, weight loss, or blood in the stool, seek medical advice promptly.
When it’s normal vs. abnormal
Occasional watery stools due to diet changes are usually harmless. However, if diarrhoea lasts over 48 hours or is accompanied by vomiting, fever, or blood in the stool, medical attention is needed to prevent dehydration.

Common causes of loose bowel movements in children
Viral Infections
Rotavirus and norovirus are the leading causes of diarrhoea in small children. These viral infections can often cause significant discomfort but usually resolve within a few days. Also, hydration is key to managing symptoms.
Bacterial infections
Bacterial infections can cause more severe diarrhoea and may require medical intervention. Symptoms often include high fever and bloody stools. Practising good hygiene and food safety can reduce the risk of bacterial infections.
Food intolerances or allergies
Lactose intolerance or gluten sensitivity can lead to chronic diarrhoea and digestive discomfort. Identifying trigger foods and eliminating them from your child’s diet is an effective way to manage diarrhoea-related symptoms.
Medications and antibiotics
Certain medications, particularly antibiotics, can upset the balance of gut bacteria and cause temporary diarrhoea. Probiotics can help restore gut health, but it’s important to consult a healthcare provider if symptoms persist.

When to be concerned about loose bowel movements
Severe dehydration
If your child shows signs of dehydration, such as dry mouth or lethargy, it’s important to seek medical help. Rehydration solutions are critical in restoring lost fluids and electrolytes.
Blood in the stool
Blood in the stool is a red flag and may indicate a more serious underlying issue, such as a bacterial infection or gastrointestinal disorder. Immediate medical attention is necessary.
Diarrhoea lasting more than 48 hours
If diarrhoea lasts for more than two days, it’s important to consult a gastrointestinal specialist to rule out underlying conditions and prevent further complications like dehydration.
Accompanying fever or vomiting
If diarrhoea is accompanied by a high fever or vomiting, medical consultation is highly recommended. These symptoms could indicate a more severe infection or underlying condition.
