Living with Congenital generalized lipodystrophy

A rare condition with almost no body fat and a very muscular look, which affects blood sugar, blood fats and the liver.

Understanding Congenital generalized lipodystrophy

Congenital generalized lipodystrophy, also called Berardinelli-Seip congenital lipodystrophy, is a rare condition with an almost total lack of body fat.

People look very muscular. Fat is stored in places like the liver and muscles instead, which causes health problems. Signs are usually seen from birth or early childhood. Common features include insulin resistance that can lead to diabetes, high triglycerides, a fatty and enlarged liver, and in some people thickened heart muscle.

Signs & symptoms

Symptoms vary from person to person. GARD's summary lists these features:

  • Almost no body fat, with a muscular look
  • Insulin resistance and diabetes
  • High triglycerides (blood fats)
  • Fatty, enlarged liver
  • Pancreas inflammation (pancreatitis)
  • Thickened heart muscle in some

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.
