Living with Hereditary spherocytosis

An inherited red blood cell condition that can cause anemia, yellow skin and eyes, and an enlarged spleen.

Understanding Hereditary spherocytosis

Hereditary spherocytosis is an inherited condition of red blood cells that often causes anemia, jaundice, and an enlarged spleen.

There are four forms: mild, moderate, moderate/severe, and severe. People with the mild form may have very mild anemia or none. The moderate form brings anemia, jaundice, and an enlarged spleen, often with gallstones. Newborns often have severe anemia that improves after the first year. People with the severe form need frequent blood transfusions and may have short stature, delayed puberty, and bone differences.

Signs & symptoms

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

  • Anemia
  • Yellowing of skin and eyes (jaundice)
  • Enlarged spleen
  • Gallstones
  • Pale skin
  • Enlarged liver

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 blood and bone marrow specialists and genetic specialists.

  3. Ask which tests can help

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