Do environmental factors play a role in the progression of beta-thalassemia?

No, but. . . Environmental factors generally do not play a role in beta thalassemia. However, a patient can be worsened by conditions that typically worsen anemia, such as dietary iron deficiency, other nutrient deficiencies (such as folate (folic acid) or vitamin b12), lead poisoning, or infections with viruses that can cause anemia (such as parvovirus b19). Vacationing at high altitudes may cause symptoms of low oxygen.
