Soiling (child pooing their pants)

Soiling is when a child regularly poos their pants. If they're already potty-trained, the soiling is usually because they are badly constipated. Treatment from a GP can help.

Causes of soiling

You may feel angry or frustrated when your child keeps pooing their pants (soiling). But they are not doing it on purpose and may not even realise it's happening.

Soiling usually happens when a child is so constipated that a large, hard piece of poo becomes stuck at the end of their gut (rectum).

Fresh poo from higher up the gut then runs around the hard poo and leaks out, staining their pants.

Signs your child is badly constipated

If your child is constipated, they may have:

  • runny poo (you may mistake this for diarrhoea) or bits of hard poo appearing regularly in their pants
  • pain when they poo – they may try to hold in their poos because of this
  • some bleeding during or after pooing, because their poo is large and hard
  • stomach pain that comes and goes
  • a poor appetite or stomach pain that improves after they poo
  • big, hard poos, or small poos like "rabbit droppings"
  • fewer than 3 poos a week

Non-urgent advice: See a GP if:

  • your child is regularly pooing their pants (soiling)

It's important not to try to sort out soiling by yourself.

Urgent advice: Ask for an urgent GP appointment or get help from NHS 111 if:

  • your child is pooing their pants (soiling), has a swollen tummy and is being sick
  • your child is soiling and has numbness or weakness in both legs

You can call 111 or get help from 111 online.

Treatment for soiling from a GP

If your child is pooing their pants (soiling) because they're constipated, a GP can prescribe laxatives to clear out the hard poo and get your child pooing regularly and comfortably again.

This can take a few months to work. The GP will want to see your child regularly to check how they are doing.

The soiling may get worse before it gets better.

A GP may refer your child to a specialist for treatment if they think soiling could be caused by another medical condition.
