Living with Thalassemia

An inherited blood condition in which the body makes too little working hemoglobin, which can cause anemia and tiredness.

Understanding Thalassemia

Thalassemia is an inherited blood condition that lowers the body's production of working hemoglobin, the protein in red blood cells that carries oxygen.

There are two main types, alpha thalassemia and beta thalassemia. Signs and symptoms vary and may include mild to severe anemia, paleness, tiredness, and bone problems.

Signs & symptoms

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

  • Mild to severe anemia
  • Paleness
  • Tiredness (fatigue)
  • Yellowing of the skin (jaundice)
  • Bone problems

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.

  4. Connect with expert centers

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

Everyday life

Living with a rare condition is easier with support.

  • Connect with Cooley's Anemia Foundation
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Which type of thalassemia do I or my child have?
Which blood tests and genetic tests confirm the type?
Which specialists, such as a hematologist, should be on my care team?

Quick facts

Beta thalassemia is caused by changes in the HBB gene, and alpha thalassemia by changes in the HBA1 and/or HBA2 genes. Both are autosomal recessive, so a child inherits a changed copy of the gene from each parent.

Also known as: hereditary leptocytosis; sickle-cell thalassemia with crisis; sickle-cell thalassemia without crisis; thalassemia hb-s disease with crisis; thalassemia hb-s disease without crisis; thalassemia syndrome
