Living with Alpha Thalassemia

A blood disorder in which the body makes less hemoglobin, the protein that carries oxygen, leading to anemia.

Understanding Alpha Thalassemia

Alpha thalassemia is a blood disorder that reduces the production of hemoglobin, the protein in red blood cells that carries oxygen.

With less hemoglobin, tissues may not get enough oxygen. People can also have anemia (a shortage of red blood cells), which can cause pale skin, weakness, and tiredness. Two types cause health problems: the more severe hemoglobin Bart hydrops fetalis syndrome (Hb Bart syndrome), and the milder HbH disease. Hb Bart syndrome involves fluid buildup in the body before birth, severe anemia, an enlarged liver and spleen, and heart or urinary system differences.

Signs & symptoms

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

  • Anemia (a shortage of red blood cells)
  • Pale skin and tiredness
  • Enlarged liver and spleen
  • Heart failure
  • Fluid around the heart or lungs
  • Swelling throughout the body (edema)

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, genetic specialists and kidney specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    Cooley's Anemia Foundation may keep lists of experts for this condition.
