Living with Hemolytic-uremic syndrome

A kidney condition in which damaged red blood cells clog the kidneys' filters, most often affecting children.

Understanding Hemolytic-uremic syndrome

Hemolytic uremic syndrome (HUS) is a kidney condition in which destroyed red blood cells block the kidneys' filtering system.

Damaged red blood cells clog the glomeruli, the tiny filters in the kidneys, so the kidneys cannot do their job. This can lead to acute kidney injury, a sudden and temporary loss of kidney function. GARD says HUS is the most common cause of acute kidney injury in children.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Based on the summary, it can lead to:

  • Red blood cell destruction
  • Clogged kidney filters
  • Sudden loss of kidney function (acute kidney injury)

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 kidney specialists.

  3. Ask which tests can help

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

Quick facts

GARD explains that red blood cells are destroyed and then block the kidneys' filters. It doesn't describe what triggers this.
