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

Colonic polyps

Colonic polyps – also known as colorectal polyps or colon polyps; these are tissue masses in the colon or rectum that can become cancerous.

Colorectal cancer

Colorectal cancer – benign or malignant tumors in the colon and rectum.


Diverticulitis – inflammation (swelling) or infections of diverticulosis pouches, located in the colon. Occurs when the wall muscles of the colon weaken and lose elasticity (ability to expand/contract) due to continual stress from hardened stools. This also includes Pediatric Meckel’s diverticulum.

Irritable bowel syndrome (IBS)

Irritable bowel syndrome (IBS) – also known as spastic colon, this condition is associated with bloating, constipation, diarrhea, gas and pain.

Ulcerative colitis

Ulcerative colitis – a form of inflammatory bowel disease (IBD) where the intestinal lining becomes inflamed.

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

Celiac disease –  a painful, immune system reaction that occurs when the child eats gluten (protein found in barley, rye and wheat).

Intestinal malrotation

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

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)

Inflammatory bowel disease (IBD) – when a child has inflammation of the digestive tract.

Ulcerative colitis

Intestinal atresia (IA)

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)

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)
