Overview

About constipation - child

Constipation in children often causes hard, painful, or infrequent stools and may lead to stool withholding.

Causes

What can cause it?

Children may become constipated from stool withholding, painful prior stool, toilet-training stress, diet, low fluid intake, routine changes, or some medicines.

Rarely, an anatomic, endocrine, or neurologic condition is responsible.

Symptoms

What a patient may notice

Symptoms vary from person to person. Possible signs may include:

  • Hard or pellet-like stool
  • Pain or crying with bowel movements
  • Belly discomfort, stool withholding, or small stool leaks
Exams and Tests

How clinicians find the cause

The clinician reviews age, stool pattern, growth, diet, toilet behavior, medicines, and examination. Imaging or laboratory tests are used selectively.

Treatment

Treatment and next steps

  1. 1

    Treatment may include disimpaction followed by a maintenance stool-softening plan prescribed for the child's age and weight.

  2. 2

    Regular toilet sitting, positive reinforcement, fiber, and fluids support recovery.

  3. 3

    Stopping treatment too early commonly causes recurrence.

Supporting recovery

  • Keep a stool calendar and use calm, nonpunitive toilet routines.
  • Give only child-specific medicine directed by a clinician.
Outlook (Prognosis)

What to expect

Most children improve with a consistent plan that makes stools soft and removes fear or pain around bowel movements. Treatment often needs to continue for weeks or months after symptoms improve because stopping too early can lead to another cycle of withholding and hard stool. Follow-up helps adjust the plan as the child grows.

Possible complications

  • Fecal impaction with abdominal pain or stool leakage into underwear
  • Anal fissures, bleeding, or worsening stool withholding after painful bowel movements
  • Urinary symptoms, reduced appetite, or recurring constipation when treatment ends too soon
Follow-up: Green vomit, severe swelling or pain, blood with illness, poor growth, unusual sleepiness, or inability to drink needs urgent care.
Prompt evaluation

When to Contact a Medical Professional

Arrange an evaluation when symptoms are new, worsening, interfering with normal activities, or not improving as expected.

Seek emergency care for green vomit, severe or worsening pain, a swollen hard belly, blood with illness, unusual sleepiness, or inability to drink.
Call 911 now

Get emergency help for severe trouble breathing, new chest pressure, fainting, seizure, sudden weakness on one side, uncontrolled bleeding, blue or gray lips, or a person who is difficult to wake.

Prevention

Ways to lower risk

  • Maintain regular toilet time, age-appropriate fiber and fluids, and activity.
  • Address painful stool early.
