What are pediatric intestinal disorders?

The small and large intestines (colon or bowel) are part of the digestive system. About 90% of the digestion and absorption of nutrients occur in the small intestine. Disorders or injuries to the intestines can cause pain, disrupt digestion, slow development, or create life-long or life-threatening complications.

What are the different types of pediatric intestinal disorders?

There are several types of intestinal disorders, including those noted below. They can be found in the small or large intestine only, or in both.

Large intestine disorders

Small intestine disorders

  • Adenocarcinoma - starts in the cellular lining of the small intestine and is the most common type of small intestine cancer.
  • Celiac disease - a painful, immune system reaction that occurs when the child eats gluten (protein found in barley, rye and wheat).
  • Intestinal malrotation - a congenital disorder where the intestines rotate incorrectly and are mainly found on the right side.

Small and large intestine disorders

  • Bleeding - a general disorder caused by ulcers, cancer, diverticulitis or polyps. Surgery may be necessary to determine the cause.
  • Crohn's disease - an inflammation of the digestive system. It affects any area of the intestines from the mouth to the anus, but often impacts the lower section of the small intestine (ileum).
  • Infections - can be viral, bacterial or parasitic, including gastroenteritis (inflammation in the stomach and small intestine) and tapeworms.
  • Inflammatory bowel disease (IBD) - when a child has inflammation of the digestive tract.
  • Ulcerative colitis
  • Intestinal atresia (IA) - occurs when a child’s intestine doesn’t properly form during development and prevents food and bowel movements from properly moving through digestion stages.
  • Obstructions (blockages) - happen for several reasons, including damaged sections from Crohn’s disease or diverticulitis, hernias, medications and scar tissue. Obstructions can also prevent food from digesting and bowel movements.

What are the signs and symptoms of pediatric intestinal disorders?

The type of condition defines the symptoms. Symptoms will appear at various ages, locations and range in severity. Children can experience one or more of the following:

What are the causes of pediatric intestinal disorders?

Intestinal disorders can result from a number of conditions. Each condition has its own cause and average age of diagnosis. The disorders can occur for many reasons, and include:

  • Autoimmune response (body attacks healthy cells)
  • Cancer
  • Congenital (present at birth)
  • Environmental (cigarette smoke or drinking household cleaners)
  • Genetic/hereditary (passed down through families)
  • Unknown triggers (idiopathic)
