Antiphospholipid syndrome makes the blood clot too easily. This can lead to miscarriage and other serious pregnancy problems. It can also lead to a stroke or heart attack. And it can lead to blood clots in the legs or lungs that may cause death.
Antiphospholipid syndrome is caused by antibodies. Normally, the body makes antibodies that attack germs like bacteria or a virus. But with this syndrome, antibodies attack parts of your blood that affect how easily it clots.
This syndrome is most often treated with blood thinners. If you are pregnant, you will need treatment. Your health will be closely watched.
