Living with Duodenal atresia

A rare condition present at birth in which a short part of the first section of the small intestine is blocked.

Understanding Duodenal atresia

Duodenal atresia is a rare condition present at birth in which a short part of the duodenum, the first part of the small intestine, is completely blocked.

The blockage can cause vomiting. It may be noticed before birth, when an ultrasound shows a 'double bubble' sign or extra amniotic fluid (polyhydramnios). It is not part of a syndrome with other features. Babies are sometimes born early.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Blocked or narrowed first part of the small intestine
  • Vomiting
  • Extra amniotic fluid during pregnancy
  • 'Double bubble' sign on prenatal ultrasound
  • Premature birth

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.
