Living with Combined pancreatic lipase-colipase deficiency

A rare genetic condition from birth where the body cannot absorb fat well, causing greasy, foul-smelling stools.

Understanding Combined pancreatic lipase-colipase deficiency

Combined pancreatic lipase-colipase deficiency is a rare condition affecting how the body absorbs and moves fats, starting from birth.

The pancreas does not make enough of two enzymes, lipase and colipase, that break down fat. This causes fatty, foul-smelling stools from birth and low levels of carotene and vitamin E in the blood. People are otherwise healthy and develop normally, with no apparent pancreas disease.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes:

  • Fatty, foul-smelling stools from birth (steatorrhea)
  • Low carotene in the blood
  • Low vitamin E in the blood

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.
