What Is The Treatment Procedure For Thalassemia?

Hello Doctor, i wanted to ask you about Thalassemia. Since,it is a genetic form of anemia, is there any chances that it can be treated? What about change in lifestyle (doing sport activities, eating healthy & etc), does that help in reducing the problem/illness? Can Thalassemia be a major problem to the person? What are the chances that it can passed to the nest heir / generation? Is losing appetite one of the factor / causes by Thalassemia? If that person having Thalassemia (minor stage), what do you recommend?
