Overview
Autoantibodies damage proteins that are attached to fat molecules (phospholipids) causing blood clots to form in the body’s arteries and veins and making the blood “stickier” than normal. This is dangerous because it causes an increased risk of abnormal blood clotting. APS is a systemic autoimmune disorder characterized by an increased risk for arterial, venous and/or microvascular thrombosis and various obstetric complications.
