What Is Beta Thalassemia?
Beta thalassemia is an inherited blood disorder that affects the body’s ability to make normal hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen throughout the body.
When hemoglobin levels are low, anemia can develop. Some people have mild symptoms, while others may experience more serious health problems that require ongoing medical care.
Beta thalassemia is caused by inherited genetic changes passed down from one or both parents. The condition is more common in people with Mediterranean, Middle Eastern, African, or Asian backgrounds.
Symptoms
Symptoms of beta thalassemia can vary depending on how severe the condition is. Mild forms may cause few or no symptoms, while severe forms can affect growth, energy levels, and organ function.
Common symptoms may include:
- Fatigue or weakness
- Pale or yellowish skin
- Slow growth in children
- Poor appetite
- Frequent infections
- Enlarged spleen
- Abdominal swelling
- Weak or fragile bones
How Is It Diagnosed?
Healthcare providers usually diagnose beta thalassemia through blood testing. A complete blood count (CBC) can check for anemia and changes in red blood cells.
Additional tests, such as hemoglobin electrophoresis and genetic testing, help confirm the diagnosis and identify the specific type of thalassemia. In some cases, prenatal testing may be available during pregnancy.
How Is It Treated?
Treatment depends on how severe the condition is. People with mild beta thalassemia may not need regular treatment, while more serious forms often require lifelong care.
Treatment options may include:
- Regular blood transfusions
- Iron chelation therapy to manage excess iron
- Folic acid supplements
- Monitoring of heart and liver health
- Surgery to remove the spleen in some cases
- Bone marrow or stem cell transplant for selected patients
Ongoing medical follow-up is important to help prevent complications and support long-term health.
