Living with Multiple gastrointestinal atresias

A rare condition in which parts of the intestine are blocked from before birth, causing problems in newborns.

Understanding Multiple gastrointestinal atresias

Multiple gastrointestinal atresias is a rare condition in which many sections of the intestine are closed or blocked from before birth.

In this condition, there are many blocked segments (atresias) in the small bowel or large bowel. This causes signs of a blockage in newborns, such as vomiting, a swollen belly, and being unable to pass the first stool (meconium). It can sometimes be seen during pregnancy.

Signs & symptoms

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

  • Blocked sections of the intestine (atresia)
  • Narrowing of the first part of the small bowel
  • Extra amniotic fluid in pregnancy (polyhydramnios)
  • Vomiting in newborns
  • Swollen belly
  • Unable to pass the first stool (meconium)

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.
