Published: May 13, 2024
Identifying risk factors for antiphospholipid syndrome (APS) can help prevent its complications. Discover what makes some people more susceptible to this condition.
Contents
Genetic and Autoimmune Links
APS risk can be higher in individuals with a family history of autoimmune diseases. It's also commonly seen in people with systemic lupus erythematosus (SLE) or other autoimmune disorders. Genetic predispositions can lead to increased production of antiphospholipid antibodies, setting the stage for APS.
Environmental Triggers
Certain infections or medications can temporarily increase the levels of antiphospholipid antibodies. These transient antibodies might not cause APS but can complicate its diagnosis. Understanding these environmental triggers helps in distinguishing between temporary and persistent antibody presence.

Lifestyle Factors
Lifestyle choices such as smoking or using estrogen-containing contraceptives can amplify the risk of blood clots in individuals with APS. Managing these factors is crucial in preventing thrombotic events and managing APS effectively.
Frequently Asked Questions
