Secondary systemic amyloidosis is a disorder in which abnormal proteins build up in tissues and organs. Clumps of the abnormal proteins are called amyloid deposits.
Secondary means it occurs because of another disease or situation. For example, this condition usually occurs as a result of chronic infection or chronic inflammatory disease. Primary amyloidosis means there is no disease that is causing the condition.
Systemic means body-wide. For example, a systemic disease affects the entire body.
Amyloidosis - secondary systemic
The exact cause of amyloidosis is unknown. You are more likely to develop secondary systemic amyloidosis if you have a long-term infection or inflammation.

Call your health care provider if you have symptoms of this condition. The following are serious symptoms that need prompt medical attention:
If you have a disease that's known to increase your risk of this condition, make sure you get it treated. This may help prevent amyloidosis.
