What is alpha thalassemia?
Alpha thalassemia is an inherited blood disorder that affects the body’s ability to make normal hemoglobin. Hemoglobin is the part of red blood cells that carries oxygen throughout the body. When hemoglobin levels are low, the body may not get enough oxygen, which can lead to anemia.
This condition is passed down through families and can range from very mild to severe. Some people have no symptoms at all, while others may need ongoing medical care.
Alpha thalassemia happens when changes in the alpha-globin genes reduce the body’s ability to make healthy hemoglobin. The condition is inherited from one or both parents.
It is more common in people with family roots in Africa, the Mediterranean region, the Middle East, India, Southeast Asia, and parts of China.
Symptoms
Symptoms of alpha thalassemia can vary depending on how severe the condition is. Mild forms may cause few or no symptoms, while more serious forms can affect daily life.
Common symptoms may include:
- Fatigue or low energy
- Pale or yellowish skin
- Weakness
- Shortness of breath with activity
- Difficulty exercising
- Enlarged spleen or liver
- Slow growth in children in severe cases
How is it diagnosed?
Healthcare providers diagnose alpha thalassemia using blood tests and a review of your medical and family history. Testing helps determine whether anemia is present and whether the condition has been inherited.
Common tests include:
- Complete blood count (CBC)
- Hemoglobin testing or electrophoresis
- Iron studies
- Genetic or DNA testing
During pregnancy, prenatal testing may be recommended if there is a known family history or increased risk for severe forms of thalassemia.
How is it treated?
Treatment depends on the type of alpha thalassemia and how severe the symptoms are. People with mild forms may only need regular monitoring, while more serious cases may require ongoing treatment.
Treatment options may include:
- Folic acid supplements
- Blood transfusions
- Iron chelation therapy to manage excess iron
- Medicines and lifestyle adjustments to avoid complications
- Surgery to remove the spleen in certain cases
Many people with mild alpha thalassemia live healthy, active lives. Those with moderate or severe disease may benefit from long-term care with blood specialists and regular follow-up visits.
