Obesity and diabetes are risk factors for venous thromboembolism, a large US study shows.
Venous thromboembolism is when a vein is blocked or partially blocked (embolism) by a blood clot (thrombus) which originates somewhere else in the body.
But other cardiovascular risk factors such as smoking, dyslipidaemia (e.g. high cholesterol), physical inactivity, and alcohol consumption were not linked to an increased risk of venous thromboembolism, as might have been expected (Archives of Internal Medicine 2002; 162: 1182-89).
The 8-year study followed 19,293 people without the condition. It established that people with a body mass index (BMI) greater than 30 had 1.5 to 2.5 times the risk of venous thromboembolism.
People with diabetes had one-and-a-half times the risk of venous thromboembolism than people without diabetes.
