What can I expect if I have antithrombin deficiency?

One of every two to three people with this problem may develop blood clots in adulthood. Your risk of clots is higher if you have surgery or don’t move your body enough. As you get older, that increases your risk, too. If you have antithrombin deficiency, unusual blood clots can develop during pregnancy or after your baby is born.
