Living with Beta Thalassemia

A blood condition in which the body makes less hemoglobin, causing anemia.

Understanding Beta Thalassemia

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

Low hemoglobin and a shortage of red blood cells (anemia) can cause pale skin, weakness, and tiredness. There are two types. Thalassemia major is more severe, starts in the first 2 years of life, and often needs regular blood transfusions. Thalassemia intermedia is milder and may start in early childhood or later. Frequent transfusions can lead to iron buildup.

Signs & symptoms

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

  • Low red blood cells (anemia)
  • Pale skin
  • Muscle weakness and irritability
  • Enlarged spleen or liver
  • Low bone density
  • Skull and bone shape changes

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, hormone 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 and Pituitary Network Association may keep lists of experts for this condition.
