What are the side effects of bone marrow transplantation tor thalassemia?

Many possible: Possible side effects from a bone marrow transplant include: rejection of the donor marrow, graft vs. Host disease (donor cells attack the recipient), infections (bacterial, viral, fungal, etc...), mouth sores, stomach ulcers, diarrhea, liver disease, seizures, nerve pain, lung inflammation, hormonal deficiencies, osteoporosis, future cancers, etc...

Many risks: Chemotherapy is often used to prepare your bone marrow to receive the transplant and can have many side effects. You will be at increased risk of infection until the new bone marrow "takes hold". Immune cells in the transplant can also attempt to "reject" your body, called graft vs host disease. For certain diseases, the benefits outweight the risks. Be sure to discuss this with your hematologist.
