The early side effects of transplants are mostly from the high-dose chemotherapy you get before the transplant, not from the transplant itself and should go away as you recover. The most common side effects listed here vary based on whether the transplanted cells came from you or from a donor. Ask your doctor which side effects you are most likely to have:
Shortness of breath
Chest pain or tightness
Fever or chills
Strange taste in your mouth (from the preservative used to freeze stem cells)
Your doctor may also do blood tests during your treatment to check for low blood cell counts. And he or she will also check your blood pressure to make sure it is not low.
Some side effects may be long-lasting or appear years later. These are possible long-term side effects:
Shortness of breath, often caused by radiation damage to the lungs
Bone damage, called aseptic necrosis, due to lack of blood supply
Another form of cancer
Severe skin rashes with itching, severe diarrhea, fatigue, and muscle aches. These symptoms may indicate graft-versus-host disease, a condition that occurs if the immune system cells in the donor’s stem cells attack your skin, liver, gastrointestinal tract, mouth, or other organs.
Lack of menstrual periods, which may indicate ovary damage and cause infertility
Vision problems caused by damage to the lens of the eye
Weight gain, which may be a sign of thyroid gland damage
