Constipation means that bowel movements are hard and dry, difficult or painful to pass, and less frequent than usual. It is a common problem for children, but it is usually temporary and no cause for parents to be concerned.

When a child does not eat enough fiber, drink enough liquids, or get enough exercise, constipation is more likely to occur. It also happens when children ignore the urge to have a bowel movement, which they often do out of embarrassment to use a public bathroom, fear or lack of confidence in the absence of a parent, or unwillingness to take a break from play. Sometimes constipation is caused by medicines or a disease.

Symptoms of constipation include:

  • No bowel movement for several days or daily bowel movements that are hard and dry
  • Cramping abdominal pain
  • Nausea
  • Vomiting
  • Weight loss

Liquid or solid, clay-like stool in the child’s underwear is a sign that stool is backed up in the rectum

Constipation can make a bowel movement painful, so the child may try to prevent having one. Clenching buttocks, rocking up and down on toes, and turning red in the face are signs of trying to hold in a bowel movement.

Treatment depends on the child’s age and the severity of the problem. Often eating more fiber (fruits, vegetables, whole-grain cereal), drinking more liquids, and getting more exercise will solve the problem. Sometimes a child may need an enema to remove the stool or a laxative to soften it or prevent a future episode. However, laxatives can be dangerous to children and should be given only with a doctor’s approval.

For infants who are drinking formula, 1 tablespoon of dark corn syrup per 3-4 oz of formula, given 2-3 times daily may help with constipation.  For breastfeeding babies, we can prescribe a gentle laxative such as lactulose.

For older children, a safe stool softener named polyethylene glycol (e.g., Miralax) can be prescribed by our office.  Regardless what intervention you choose though, give it at least 2-3 days to work.

Although constipation is usually harmless, it can be a sign or cause of a more serious problem. A child should see a doctor if :

  • Episodes of constipation last longer than three weeks
  • The child is unable to participate in normal activities
  • Small, painful tears appear in the skin around the anus
  • A small amount of the intestinal lining is pushed out of the anus (hemorrhoids)
  • Normal pushing is not enough to expel stool
  • Liquid or soft stool leaks out of the anus
