Bone marrow donation is primarily a donation of blood stem cells, which is the extraction of bone marrow blood, which contains a large amount of blood stem cells for patients in need. Bone marrow donation has no adverse effects on the donor’s own body and does not affect health. The human body contains many types of blood cells, all of which come from hematopoietic stem cells. The hematopoietic stem cells can replicate cells that are identical to their own, making the body’s hematopoietic function uninterrupted. When the old blood cells die, the new ones grow up to replace them. When some blood stem cells in the body are damaged, healthy stem cells are quickly born to compensate. When donating bone marrow, only a small portion of the bone marrow is taken from the body and only some of the blood stem cells are lost. Therefore, blood stem cell donation will not affect the blood production function of a person, and there is no harm to the donor itself. Of course, there will be a transient decrease in resistance and immunity after bone marrow donation, but after bone marrow donation, as long as good rest and nutrition can completely recover, you can rest assured that bone marrow donation, after donation, pay attention to good rest.
