At The Children's Naturopath, we frequently see children experiencing recurring tummy aches, sometimes for months or even years, without parents being able to identify a consistent cause.
With over 28 years of clinical experience in children's health, we pay particular attention to the relationship between food, bowel movements and the timing of abdominal pain.
One of the most useful questions we ask parents is whether their child's tummy pain occurs immediately after eating, several hours later, before a bowel movement or at particular times of the day.
Persistent or severe tummy pain should always be assessed by your child's doctor first, so that medical causes can be excluded. What follows is about what we look at alongside that.
Something we regularly discuss with parents is that even nutritious foods may not agree with every child.
For example, a child may tolerate a small amount of a particular food once daily but experience abdominal pain when eating larger portions or consuming the same food several times throughout the day.
This is an important consideration with food intolerances, where the amount and frequency of exposure can influence symptoms.
Common foods we explore include dairy products, wheat and gluten-containing foods, particularly when parents notice recurring pain, bloating or changes in bowel movements.
Where a dietary trial is appropriate, we keep it short and structured, with careful reintroduction — and we supervise it. Children should not be put on long-term exclusion diets without guidance, because removing food groups carries its own nutritional risk.
One of the most overlooked contributors to abdominal discomfort in children is constipation.
Parents sometimes tell us their child is not constipated because they pass a bowel movement every second or third day. However, infrequent bowel movements can contribute to abdominal pain, bloating, reduced appetite and general discomfort.
In clinic, we encourage parents to observe not only how often their child passes a stool, but also its consistency and whether they appear to empty their bowels comfortably.
A simple observation we sometimes use is the corn test, where parents note how long it takes for corn eaten at dinner to appear in the stool.
This gives a rough indication of intestinal transit time. It is an everyday observation, not a clinical measurement.
Rather than removing numerous foods at once, we encourage parents to identify patterns. For two weeks, record:
What the child eats, and approximately how much.
When tummy pain begins and how long it lasts.
Whether pain occurs before or after bowel movements.
Stool frequency and consistency.
Any associated bloating, wind, nausea or reflux.
Whether the same food causes symptoms every time, or only when eaten more frequently.
For example, a child may tolerate a quarter cup of a particular food once daily but experience discomfort after eating it twice in the same day.
Recognising these patterns helps us develop a more individualised nutritional approach without unnecessarily restricting the child's diet.
Another important part of our clinical approach is understanding how digestive discomfort affects a child's everyday life.
We often hear that children experiencing ongoing tummy pain become reluctant to eat, lose interest in meals or experience changes in sleep, mood and concentration.
Our aim is to understand the relationship between their symptoms, dietary intake and bowel habits so that we can identify practical changes to support digestive comfort and overall wellbeing, alongside their existing care.
