Can Thalassemias Be Prevented?

Thalassemias can't be prevented because they're inherited (passed on from parents to children). However, these bleeding disorders can be found before birth through prenatal tests.

Family genetic studies may help find out whether people have missing or altered hemoglobin genes that cause thalassemias. (For more information, see "How Are Thalassemias Diagnosed?")

If you know of family members who have thalassemias and you're thinking of having children, consider talking with your doctor and/or a genetic counselor. They can help determine your risk for passing on the disorder to your child.
