What are the risk factors for antiphospholipid syndrome?

While researchers aren’t sure what exactly causes antiphospholipid syndrome, the following things are considered risk factors for developing it:

• Being female: Approximately 70% of people who have antiphospholipid syndrome are female.
• Having other autoimmune disorders: Approximately 30% to 40% of people who have lupus (systemic lupus erythematosus or SLE), an autoimmune disorder, have antiphospholipid syndrome.
• Having a rheumatic disorder: Rheumatic disorders affect your joints, bones or muscles. People who have a rheumatic disorder are more likely to have antiphospholipid syndrome.
• Having a family history of antiphospholipid syndrome: The syndrome sometimes runs in families.
