If a bone marrow transplant is unsuccessful and the situation is more serious, the patient may choose to have another transplant or other treatments according to his/her situation. 1. Bone marrow transplantation is the treatment of a range of diseases by intravenous infusion of hematopoietic stem cells to rebuild the patient’s normal hematopoietic and immune systems. Generally, if a patient fails to undergo a bone marrow transplant, it may cause severe bone marrow suppression, complicated by serious infections, organ failure, etc., which can be life-threatening in serious cases. 2. Patients can take into account their own situation, as well as their personal needs, and under the guidance of the doctor for another bone marrow transplant. Usually the failure rate of bone marrow transplantation is small. When the initial transplantation of bone marrow fails, autologous transplantation can choose the backup bone marrow or stem cells for re-transplantation, and allogeneic transplantation can be carried out by extracting the donor’s stem cells for transplantation for the second time. For patients who want to have a bone marrow transplant, they need to ask their doctors for guidance in light of their own situation. In daily life, ensure sufficient sleep time and do not overwork. In terms of diet, eat more fresh fruits and vegetables and less spicy, cold and stimulating foods. Specific treatment should be carried out under the guidance of a physician.
