Reducing the risk of venous thrombosis in pregnancy and after birth

Thrombosis is a blood clot in a blood vessel (a vein or an artery). Venous thrombosis occurs in a vein. Veins are the blood vessels that take blood towards the heart and lungs; arteries take the blood away.

A deep vein thrombosis (DVT) is a blood clot that forms in a deep vein of the leg, calf or pelvis.

This information is about reducing the risk of a venous thrombosis if you are thinking about having a baby, you are already pregnant or you have just had a baby.
