Good morning @martetom, Welcome to Mayo Clinic Connect. For your first time posting you’re jumping right in with a biggie! If you’re at the point where you’re ready for a BMT you’ve already gone through a rough patch in your life. If you don’t mind my asking, what medical adventure led you to needing a bmt?
There are different types of Stem Cell/Bone Marrow transplants. The most common being Autologous, using your own cells or allogenic, using cells from a donor. When being able to use your own cells generally the pre-conditioning is shorter, recovery is faster and the length of time required at the hospital is less. The cells already recognize the body so there is no concern for rejection.
The allo transplant, using cells from a donor, requires a longer preconditioning treatment, recovery is slower and the usual required time at the transplant location is at least 100 days. There can be some challenges with the new cells wanting to play nice with its host…your body…but these are all worked around and the gift is a second chance at life! Definitely worth the journey!

With both transplants, there is nausea and fatigue. But, as you’ve most likely already experienced if you have a blood cancer, this passes.

We have a number of shared stories in a discussion I prompted after my transplant. I’d love to have you meet some fellow BMT survivors in the group: We’re all more than willing to help you out in any way we can. Please meet: alive, @waveg @edb1123 @lisal64 @pamh480 @secglc2 and others in the group!
