Thrombosis occurs when blood clots block your blood vessels. There are 2 main types of thrombosis:
- Venous thrombosis is when the blood clot blocks a vein. Veins carry blood from the body back into the heart.
- Arterial thrombosis is when the blood clot blocks an artery. Arteries carry oxygen-rich blood away from the heart to the body.
Thrombotic disorders, often known as Bleeding disorders affect a person’s ability to effectively form a blood clot (or thrombus) when an injury occurs. If you have a bleeding disorder, you may have defective or decreased platelet and/or coagulation factors which make it hard for your body to form effective blood clots normally, and you may experience bleeding complications which can range from mild to severe.
