The risk factors for venous and arterial thrombosis are different, but they are both serious medical conditions that can lead to serious complications.
Venous thrombosis is a condition where a blood clot forms in a vein. Risk factors for venous thrombosis include obesity, smoking, prolonged sitting or standing, certain medical conditions such as cancer or heart failure, and some medications, such as birth control pills. People with a family history of thrombosis and pregnant women are also at higher risk.
Arterial thrombosis is a condition where a blood clot forms in an artery. Risk factors for arterial thrombosis include high blood pressure, high cholesterol, diabetes, smoking, and a sedentary lifestyle. Certain medical conditions, such as peripheral artery disease, can also increase the risk. People with a family history of thrombosis and those who have had a heart attack or stroke are also at higher risk.
In both types of thrombosis, the risk factors can be managed or reduced by making lifestyle changes, such as quitting smoking, exercising regularly, eating a healthy diet, and controlling blood pressure and cholesterol levels. People should also talk to their doctor about any medications they are taking and discuss any family history of thrombosis.
