Living with Atresia of small intestine

A condition present from birth in which part of the small intestine has no normal opening.

Understanding Atresia of small intestine

Atresia of the small intestine is a condition present from birth in which part of the small intestine has no normal opening.

This blocks the path of food and fluid through the gut. It can be seen during pregnancy and may come with other digestive differences, like intestinal malrotation (the intestine is positioned abnormally).

Signs & symptoms

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

  • Swollen belly (abdominal bloating)
  • Vomiting
  • Feeding difficulties
  • Poor weight gain (failure to thrive)
  • Intestinal malrotation
  • Slow growth before 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.
