Living with Congenital atresia of colon

A condition present from birth in which part of the colon is closed off, blocking the bowel in newborns.

Understanding Congenital atresia of colon

Colonic atresia is a condition present from birth in which a segment of the colon is blocked.

The blockage in the lower intestine shows up in newborns as a swollen belly and not passing the first stool (meconium). It can be seen during pregnancy and in newborns.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Swollen belly (abdominal distention)
  • Not passing the first stool (meconium)
  • Colon closed off (colonic atresia)
  • Narrowed first part of the small intestine (duodenal stenosis)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include digestive system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
