There is no way to prevent thalessemia once the child is born. Genetic counseling may be helpful to couples with a family history of the disease. There is a 25% chance with each pregnancy that a child will be born with thalassemia major if both parents carry the gene for thalassemia.
Thalassemia minor usually does not cause long-term problems. Thalassemia major, however, can result in stunted growth, problems in bone development, darkened skin, general growth problems, and death.
Thalassemia is an inherited condition, so a person can passed it on to his or her children.
