What is antiphospholipid syndrome (APS)?

Antiphospholipid syndrome (APS) is sometimes known as ‘sticky blood syndrome’ or Hughes syndrome. APS can cause blood clotting in your arteries or veins and is a major cause of recurrent miscarriage. It’s also one of the most common causes of strokes in young people. It’s estimated that 1 in 5 people who’ve had a stroke before the age of 40 may have APS.

APS affects all age groups but is most common between the ages of 20 and 50. It was first diagnosed in people who had lupus (systemic lupus erythematosus) but it was later discovered that APS can occur on its own (this is called primary APS).
