Complications

The potential complications of amyloidosis depend on which organs the amyloid deposits affect. Amyloidosis can seriously damage your:

• Heart. Amyloid reduces your heart's ability to fill with blood between heartbeats. Less blood is pumped with each beat, and you may experience shortness of breath. If amyloidosis affects your heart's electrical system, your heart rhythm may be disturbed. Amyloid-related heart problems can become life-threatening.
• Kidneys. Amyloid can harm the kidneys' filtering system, causing protein to leak from your blood into your urine. The kidneys' ability to remove waste products from your body is lowered, which may eventually lead to kidney failure and the need for dialysis.
• Nervous system. You may experience pain, numbness or tingling of your fingers or numbness, lack of feeling or a burning sensation in your toes or the soles of your feet. If amyloid affects the nerves that control your bowel function, you may experience periods of alternating constipation and diarrhea. If it affects the nerves that control blood pressure, you may feel faint after standing up too quickly.
