Bone marrow transplantation (BMT), also known as a stem cell transplant, is a critical procedure used to treat a wide range of life-threatening diseases, including blood cancers like leukaemia, lymphoma, and multiple myeloma, as well as some genetic and autoimmune disorders.
Despite its life-saving potential, the process comes with various bone marrow transplant side effects for both donors and recipients. Understanding these effects can help patients and families prepare for the journey ahead.
Synopsis
Understanding Bone Marrow Transplant (BMT)
Bone marrow is the soft, spongy tissue inside bones responsible for producing blood cells – red blood cells, white blood cells, and platelets. During a bone marrow transplant, healthy stem cells are introduced into a recipient's bloodstream to replace damaged or destroyed bone marrow. The new stem cells grow and produce healthy blood cells, restoring the immune system.
There are two main types of BMT:
-
Autologous Transplant: The patient's own stem cells are used.
-
Allogeneic Transplant: Stem cells come from a donor, either related or unrelated.
Side Effects in Bone Marrow Donors
Bone marrow donors play a vital role in saving lives, but the process can have physical and emotional impacts. Here are some common bone marrow transplant side effects for donors:
|
Procedure |
Side Effects |
|
Bone Marrow Harvesting (from hip bone) |
Pain, bruising, soreness, fatigue, stiffness, minor bleeding, infection risk |
|
Peripheral Blood Stem Cell (PBSC) Donation (via apheresis) |
Muscle pain, bone pain, headache, fatigue, nausea, tingling or numbness, low calcium levels (due to the mobilising agent G-CSF) |
Other Considerations for Donors:
-
Emotional Impact: Anxiety and stress before the procedure.
-
Recovery Time: Usually 1-2 weeks for most donors, but complete recovery may take longer for some.
-
Long-Term Risks: Minimal, but may include prolonged fatigue or, in rare cases, low blood counts.
Side Effects in Bone Marrow Transplant Recipients
For recipients, the bone marrow transplant side effects can be more severe and long-lasting, as the process involves high-dose chemotherapy or radiation to destroy the diseased bone marrow before transplant. Here are some common bone marrow transplant side effects for recipients:
|
Timeline |
Potential Side Effects |
|
Immediate (Days 0-30) |
Nausea, vomiting, mouth sores, hair loss, low blood counts, infections, fatigue, loss of appetite, bleeding, organ damage (liver, lungs) |
|
Early (Days 30-100) |
Graft-versus-host disease (GVHD), severe infections, acute organ damage, veno-occlusive disease, pneumonitis |
|
Late (After Day 100) |
Chronic GVHD, cataracts, infertility, secondary cancers, lung fibrosis, joint pain, thyroid issues, psychological effects |
Graft-Versus-Host Disease (GVHD)
This is a significant risk for allogeneic transplant recipients, where the donor's immune cells attack the recipient's tissues. It can affect the skin, liver, gut, and other organs. Managing GVHD often requires long-term immunosuppressive therapy.

Factors Influencing Side Effects
Several factors influence the severity and duration of side effects, including:
-
Patient’s Age and Overall Health: Older patients or those with pre-existing conditions may experience more severe side effects due to reduced organ function and slower recovery rates.
-
Type of Transplant (Autologous vs Allogeneic): Autologous transplants generally have fewer complications as the patient’s own cells are used, while allogeneic transplants carry a higher risk of immune reactions like GVHD.
-
Compatibility between Donor and Recipient: The closer the match, the lower the risk of rejection and GVHD, making sibling or matched unrelated donor transplants generally more successful.
-
Condition being Treated: Patients with aggressive cancers or advanced diseases often require more intensive pre-transplant therapy, increasing the risk of severe side effects.
-
Supportive Care Quality: Access to high-quality, multidisciplinary care significantly impacts recovery, reducing the risk of infections and long-term complications.
Managing Side Effects
Effective management of side effects involves a multidisciplinary approach:
-
Medications for pain, nausea, and infection prevention: These include antibiotics, antivirals, and antifungals to prevent or treat infections, as well as antiemetics to control nausea and painkillers for discomfort.
-
Psychological Support to address emotional stress: Counselling, support groups, and therapy can help patients cope with the mental and emotional challenges of recovery.
-
Nutrition and Physical Therapy for strength recovery: Proper nutrition and tailored physical therapy can speed recovery and reduce the impact of muscle loss and fatigue.
-
Long-term Monitoring for late-onset complications: Regular follow-ups, blood tests, and imaging are essential to catch and manage late effects like organ damage or secondary cancers early.
Conclusion and Call to Action
Bone marrow transplantation offers a second chance at life for many patients, but it comes with significant challenges for both donors and recipients.

FAQ's
Immediate side effects typically resolve within a few weeks to months, but some long-term complications like GVHD or secondary cancers can persist for years.
Long-term risks for donors are minimal, but some may experience prolonged fatigue or low blood counts in rare cases.
The risk depends on the donor-recipient match and other factors, ranging from 30% to 70% in allogeneic transplants.
Not necessarily. Many side effects are temporary and can improve with proper medical care.
Early detection, personalised care, and close monitoring can significantly reduce the risk of severe side effects.
