Complications of multiple myeloma include:

  • Frequent infections. Myeloma cells inhibit your body's ability to fight infections.
  • Bone problems. Multiple myeloma also can 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. Higher calcium levels in the blood related to eroding bones can interfere with your kidneys' ability to filter your blood's waste. The proteins produced by the myeloma cells can cause similar problems.
  • Low red blood cell count (anemia). As myeloma cells crowd out normal blood cells, multiple myeloma can also cause anemia and other blood problems.
