Constipation in children: what causes it and what actually fixes it

What counts as constipation

Not the frequency alone. Exclusively breastfed babies can go several days without a stool and be perfectly normal if it is soft when it comes. What matters is hard, dry, pellet-like or very large stools, straining and pain, blood on the surface, and a child who is uncomfortable.

In toddlers and older children, fewer than three stools a week, painful passage, soiling in an already-trained child, or a child who dances, crosses their legs and hides to avoid going are all signs.

Common triggers: the switch to solids, the switch to cow's milk, too much milk and too little fibre and water, toilet training pressure, starting school (where children hold on because the toilets are unpleasant), illness, travel, and hot weather.

The withholding cycle

One painful stool teaches a child that going hurts. They hold on. The stool sits longer, water is absorbed, it gets harder and bigger, and the next one hurts more. Within weeks a child can be holding for days, with soiling around a hard mass.

This is why 'just give more water and fruit' often fails in an established case: the problem is behavioural as much as dietary, and the impacted stool has to be cleared before the habit can change.

Never punish or shame soiling. A child who soils with constipation is not being lazy or defiant — they usually cannot feel it happening.

What actually works

Fluids and fibre: water through the day, fruit with the skin where possible, papaya, pear, prunes and dates, vegetables, dals, whole grains — ragi, jowar, whole wheat instead of maida. Reduce milk to around 400-500 ml a day after the first birthday; excess milk is one of the commonest causes.

Routine: sitting on the toilet for five minutes after meals, especially breakfast, when the gut is most active. Feet must be supported on a stool with knees above the hips — a child whose legs dangle cannot push effectively. This one change fixes a surprising number of cases.

No pressure, no rewards for producing, no sitting for twenty minutes. Make it boring and short.

Medicine: for an established case, doctors prescribe a stool softener such as polyethylene glycol or lactulose, often for weeks or months, to keep stools soft while confidence returns. This is normal treatment, not a failure, and stopping too early is the main reason it relapses. Avoid adult laxatives, enemas at home and 'digestive' syrups given without advice.

When to see a doctor

Same-day: severe abdominal pain, a swollen hard abdomen, vomiting (particularly green vomit), no stool at all with a distended abdomen, blood in the stool beyond a streak, or constipation in a baby under one month.

Book an appointment for: constipation that does not improve within a week or two of the measures above, soiling, pain on passing stool, a fissure that keeps bleeding, poor weight gain alongside constipation, or a baby who did not pass meconium in the first 48 hours of life — that history matters and is worth mentioning.
