What is the most common symptom of antiphospholipid syndrome (APS)?

ANSWER

Blood clots are the most common APS symptom.

Deep vein thrombosis (DVT) is a clot in the deep veins of the leg. It can also happen in the arms and pelvis.

Clots in the brain can cause headaches, dementia, seizures, and strokes. Lung clots can block pulmonary arteries. And heart clots can cause blockages, heart valve damage, and heart attacks.

Women with APS can have a hard time getting pregnant, and blood clots in the placenta can cause miscarriage, premature birth, and development issues.
