Living with Congenital diaphragmatic hernia

A condition present from birth in which a gap in the diaphragm lets organs move into the chest and crowd the lungs.

Understanding Congenital diaphragmatic hernia

Congenital diaphragmatic hernia is a defect in the diaphragm, the muscle that separates the chest and abdomen.

The diaphragm may be thin in a spot or absent. The opening lets the stomach and intestines move into the chest and crowd the heart and lungs, which can leave the lungs underdeveloped. In 5 to 10 percent of people, signs appear later, and in about 1 percent there are no symptoms at all.

Signs & symptoms

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

  • Breathing difficulties
  • Underdeveloped lungs (pulmonary hypoplasia)
  • Low blood oxygen
  • Thin or missing diaphragm
  • Intestinal malrotation
  • Abdominal pain in later-onset cases

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 heart and blood vessel specialists and lung and breathing specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    CDH International and Fetal Health Foundation may keep lists of experts for this condition.
