Paediatric constipation

Constipation is one of the most common digestive problems in children. It can affect babies, toddlers and older children, and is often distressing for both the child and their parents. While most cases aren’t serious, ongoing constipation should be addressed early to prevent discomfort and longer-term problems.

Understanding why constipation develops and how it’s managed can help families support their child’s digestive health with confidence.

What is paediatric constipation?

Paediatric constipation usually refers to infrequent bowel movements, hard or painful stools, or difficulty passing stools. Some children may pass stools less often than others, but constipation is more about stool consistency and discomfort than frequency alone.

Children with constipation may avoid going to the toilet because of pain, which can make the problem worse over time.

Common causes of constipation in children

Constipation often develops during periods of change. Toilet training, starting nursery or school, illness or changes in routine can all disrupt normal bowel habits. Diet also plays a major role, particularly low fibre intake or insufficient fluids.

In some children, withholding behaviour develops after a painful bowel movement. This leads to stool becoming harder and more difficult to pass, creating a cycle that can be hard to break without support.

Less commonly, constipation may be linked to underlying medical conditions, medication use or developmental issues, which is why persistent symptoms should be reviewed.

Signs and symptoms to watch for

Children may not always describe constipation clearly. Symptoms can include tummy pain, bloating, reduced appetite, large or hard stools, soiling of underwear and distress around toileting. Some children experience urinary symptoms, as a full bowel can press on the bladder.

Behavioural changes, such as irritability or reluctance to sit on the toilet, can also be clues that constipation is present.

When should you be concerned?

Most constipation improves with simple measures, but medical advice should be sought if symptoms are persistent, severe or affecting a child’s wellbeing. Concerns include weight loss, vomiting, blood in the stool or constipation starting very early in infancy.

A healthcare professional can assess whether constipation is functional or whether further investigation is needed.

How is paediatric constipation managed?

Management focuses on making stools softer and bowel movements more comfortable, while encouraging healthy habits. Treatment often involves a combination of dietary changes, adequate fluid intake and medication to soften stools. These treatments are safe when used correctly and are often needed for several months to allow the bowel to recover.

Establishing a regular toileting routine, with time and reassurance, is just as important as medical treatment. Punishment or pressure around toileting should be avoided, as this can worsen symptoms.

Supporting long-term bowel health

With the right care, most children recover fully from constipation. Early treatment reduces the risk of ongoing problems and helps children regain confidence around toileting.

If constipation is not improving or keeps returning, referral to a specialist may be helpful. Paediatric specialists can offer tailored advice, reassurance and ongoing support for both the child and family.

Constipation in children is common and manageable. With understanding, patience and appropriate care, most children can return to comfortable and regular bowel habits.
