Treatment for thalassemia depends on the severity of the condition. Mild cases may require little to no treatment. More severe cases may need regular blood transfusions to maintain normal hemoglobin levels. However, frequent transfusions can lead to iron overload, which requires chelation therapy to remove excess iron from the body. In some cases, a bone marrow or stem cell transplant may offer a potential cure. Supportive treatments like folic acid supplements and a nutritious diet are also beneficial.
