What is Chronic Idiopathic Constipation?

The term “idiopathic constipation” means constipation without a known cause. Children with constipation are not able to have a bowel movement on a routine basis. Often it is a very mild problem that can be solved by changes in diet and exercise. Some children suffer from chronic idiopathic constipation. This is a very severe condition that calls for high doses of laxatives and sometimes surgery. Idiopathic constipation can be managed, but not cured.

What Are the Symptoms of Idiopathic Constipation?

Symptoms may start soon after birth or when your child starts eating baby food or solid food.  You may also notice symptoms when you start to potty train your child. 

Your child may have these symptoms: 

  • Not having a bowel movement each day 
  • Bowel movements are hard 
  • May struggle with bowel movements 
  • Bowel movements may be painful 
  • May soil their underwear 

Sometimes the anus may tear when your child is passing a large, hard piece of stool.  This cut may reopen each time the child passes more stool.  The child then learns that passing stool is painful and tries to avoid it.  They hold the stool in. This makes the problem worse and harder to treat. 

When stool stays inside the intestine longer than 24 hours, the intestine stretches to hold the large amount of stool.  The stretched colon then holds more stool, making the constipation worse. 

Your child may have soiling or smearing of stool in their underwear.  The child may get used to having their underwear always dirty.  The child may get used to their own odor.  The parents must understand that the child often does not notice their own smell. 

How Is Idiopathic Constipation Diagnosed?

There are no tests for idiopathic constipation.  However, it is vital for your child’s doctor to check for other conditions before saying they have idiopathic constipation.  Your child’s doctor will order a contrast enema, a type of X-ray, to find out the degree of constipation. This will help guide your child’s treatment.

How Can Idiopathic Constipation Be Treated?

The first step is to make sure your child is on a balanced diet with plenty of fluids. Children with idiopathic constipation often need to take laxatives each day no matter how balanced their diet is. Laxatives are medicine that make the stool move through the intestine faster. Your child should have at least one bowel movement each day. This will keep the stool from getting impacted and keep your child from soiling.

Your child will go to our one-week outpatient Bowel Management Program. During this program, we are able to start laxative treatment and adjust this daily until we find the routine that works for your child. After the one-week program we will continue to follow your child and help you to manage their constipation. Growth spurts, changes in diet and other medicine can affect your child’s constipation. The Colorectal Center is here to help you manage your child’s constipation throughout these stages of their life.

Are There Surgical Options for Idiopathic Constipation?

For some children laxatives are not enough.  They may need a surgery to remove the part of the intestine that is most stretched. This surgery may help with constipation or decrease the amount of laxative that the child needs.
