Complications

Complications of multiple myeloma include:

• Frequent infections. Myeloma cells inhibit your body's ability to fight infections.
• Bone problems. Multiple myeloma can also affect your bones, leading to bone pain, thinning bones and broken bones.
• Reduced kidney function. Multiple myeloma may cause problems with kidney function, including kidney failure.
• Low red blood cell count (anemia). As myeloma cells crowd out normal blood cells, multiple myeloma can also cause anemia and other blood problems.
