Living with Intestinal pseudo-obstruction

A condition in which the intestine's muscles don't move food well, causing symptoms like a blockage without one.

Understanding Intestinal pseudo-obstruction

Intestinal pseudo-obstruction is a condition in which the muscle contractions that move food through the digestive tract don't work properly.

It can occur at any time of life, and symptoms range from mild to severe. It may come from the intestinal muscles themselves or from the nerves that control them. Partly digested food builds up in the intestines. Symptoms resemble a blockage (obstruction) but without one.

Signs & symptoms

Symptoms vary from person to person. GARD says they may include:

  • Swelling of the belly (distention)
  • Belly pain
  • Nausea and vomiting
  • Constipation or diarrhea
  • Loss of appetite
  • Trouble absorbing nutrients (malnutrition)

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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

  4. Connect with expert centers

    Association of Gastrointestinal Motility Disorders may keep lists of experts for this condition.

Quick facts

It may arise from abnormalities of the intestinal muscles themselves (myogenic) or from problems with the nerves that control them (neurogenic).
