Constipation

Children with constipation often experience the following:

  • A decrease in frequency of bowel movements, compared to a child's usual pattern (some physicians define constipation as fewer than three bowel movements per week).
  • The passage of hard, dry bowel movements.
    Bowel movements that are difficult or painful to push out.
  • Hard stools can irritate or tear the lining of the anus (fissure), making it painful to have a bowel movement. The child may avoid having a bowel movement, which can cause further constipation.

Causes

Sometimes there is no identifiable reason for constipation in children. However, some of the causes may include:

Diet

  • Consuming too many foods that are high in fat and low in fiber (such as fast foods, "junk" foods and soft drinks)
  • Not drinking enough water and liquids

Lack of Exercise

  • Exercise helps move digested food through the intestines.

Emotional Issues

  • Pre-school and school-aged children are sometimes embarrassed to use public bathrooms and hold in their bowel movements, causing constipation.
  • Toddlers can be overwhelmed by toilet training, especially when a parent is more anxious for the child to be out of diapers than the child is.
  • Toddlers can also become involved in power-struggles with their parents as they learn to assert their independence, and may intentionally hold bowel movements in.
  • Some children who experience stress at school, with their friends or in the family, may have constipation.

Busy Children

  • Some children ignore signals their intestines give them to have a bowel movement. This can happen when children are too busy playing and forget to go to the bathroom.
  • Constipation can also be a problem when children start a new school year, since they may have to change their bowel routine.
  • Once a child becomes constipated, a vicious cycle can develop. Hard, dry stools can be painful to push out, and the child can avoid using the bathroom to avoid the discomfort. Eventually, the intestine will not be able to sense the presence of stool.

Physical problems that can cause constipation include the following:

  • Abnormalities of the intestinal tract, rectum or anus
  • Problems of the nervous system, such as cerebral palsy
  • Endocrine problems, such as hypothyroidism
  • Certain medications (i.e., iron preparations and narcotics such as codeine)

Symptoms

The following are the most common symptoms of constipation. However, each individual may experience symptoms differently. Symptoms may include:

  • Not having a bowel movement for several days, or passing hard, dry stools
  • Abdominal bloating, cramps or pain
  • Decreased appetite
  • Clenching teeth, crossing legs, squeezing buttocks together, turning red in the face as the child tries to hold in a bowel movement to avoid discomfort
  • Small liquid or soft stool smears that soil the child's underwear

The symptoms of constipation may resemble other conditions or medical problems. Always consult your child's physician for a diagnosis.

Diagnosis

A physician will examine your child and obtain a complete medical history. Depending on the age of your child, you might be asked questions such as:

  • How old was your baby when they had their first stool?
  • How often does your child have a bowel movement?
  • Does your child complain of pain when they have a bowel movement?
  • Have you been trying to toilet train your toddler recently?
  • What does your child's diet consist of?
  • Have there been any stressful events in your child's life lately?
  • How often does your child soil their pants?

Occasionally, your child's physician may want to perform other diagnostic tests to determine if there are any problems. These tests may include:

  • Abdominal x-ray - A diagnostic test to evaluate the amount of stool in the large intestine.
  • Barium enema - A procedure performed to examine the large intestine for abnormalities. A fluid called barium (a metallic, chemical, chalky, liquid used to coat the inside of organs so that they will show up on an x-ray) is given into the rectum as an enema. An x-ray of the abdomen shows strictures (narrowed areas), obstructions (blockages) and other problems.
  • Anorectal manometry - A test that measures the strength of the muscles in the anus, nerve reflexes, ability to sense rectal distention and coordination of muscles during defecation.
  • Rectal biopsy - A test that takes a sample of the cells in the rectum to be examined under a microscope for any problems.

Treatment

Talk to your child's physician if:

  • Episodes of constipation last longer than three weeks.
  • The child is unable to participate in normal activities because of constipation.
  • Normal pushing is not enough to expel a stool.
  • Liquid or soft stool leaks out of the anus.
  • Small, painful tears appear in the skin around the anus.
  • Hemorrhoids develop.

Specific treatment for constipation will be determined by your child's physician based on the following:

  • Your child's age, overall health and medical history
  • Extent of the condition
  • Type of condition
  • Your child's tolerance for specific medications, procedures or therapies
  • Expectations for the course of the condition
  • Your opinion or preference

Treatment may include diet changes. Often, making changes in your child's diet will help constipation. Consider increase the amount of fiber in your child's diet by:

  • Adding more fruits and vegetables.
  • Adding more whole grain cereals and breads (check the nutritional labels on food pack ages for foods that have more fiber).

Plan to serve your child's meals on a regular schedule. Often, eating a meal will stimulate a bowel movement within 30 minutes to an hour. Serve breakfast early so your child does not have to rush off to school and miss the opportunity to have a bowel movement.

Increase Exercise

Increasing the amount of exercise your child gets can also help with constipation. Exercise aids digestion by helping the normal movements the intestines make to push food forward as it is digested.

Long-term Outlook

The outlook depends on what type of condition caused the constipation. Those children with diseases of the intestine, such as Hirschsprung's disease, may have chronic problems. However, most of the time, constipation is a temporary situation. Up to 90 percent of children will have no long term, recurring problems.
