Is obesity a risk factor for VTE?

Obesity is a common, moderate and independent risk factor for VTE in both female and male patients. The risk increases with increasing BMI. The risk of VTE is higher in obese patients aged >50 years compared to those younger than 50 years old.

How does obesity cause VTE?

Obese patients also have a risk of recurrent DVT episodes compared to non-obese individuals. Obesity leads to stasis or stagnation of blood in the veins. This also raises the risk of thrombosis and clot formation.

Is obesity a risk factor for thrombosis?

Obesity promotes chronic inflammation and impaired fibrinolysis, both of which lead to an increased risk of thrombosis.

What are risk factors for VTE?

Risk factors convincingly demonstrated for VTE include increasing age, prolonged immobility, malignancy, major surgery, multiple trauma, prior VTE, and chronic heart failure (Table 2). However, it is important to recognize that the predictive values of these factors are not equal.

Is obesity a risk factor for pulmonary embolism?

These data show that obesity is a risk factor for pulmonary embolism and deep venous thrombosis in men as well as women. Obesity seems to be a stronger risk factor in women and in men and in women less than 40 years of age.

Obesity is a well-known risk factor for clots in deep veins (usually in the legs) and for pulmonary embolism, a clot in blood vessels of the lungs that can result in sudden death or strain on the heart. Together, the two conditions are called venous thromboembolism (VTE).

Who is high risk for blood clots?

Who is at risk for a blood clot? Blood clots can affect anyone at any age, but certain risk factors, such as surgery, hospitalization, pregnancy, cancer and some types of cancer treatments can increase risks. In addition, a family history of blood clots can increase a person’s risk.

How does obesity cause Hypercoagulability?

Cytokines including interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) contribute to the obesity induced proinflammatory mileau (18-20). Hypercoagulability may be partially due to this chronic low-grade inflammation, but is likely also due to direct effects of adipose tissue on mediators of coagulation.

Can obesity cause high D dimer?

Since increase in body size is associated with coagulation activation, D-dimer is elevated in many obese patients making this laboratory tool irrelevant in excluding thrombosis. This would mean if there is a high suspicion for thrombosis in people with a high BMI, they have to undergo radiological imaging.

Can DVT cause weight gain?

Conclusions: We observed a significant weight gain after acute DVT. This weight gain was more marked in hospitalised patients than in outpatients. Our findings suggest that weight control should be considered in all patients with acute DVT.

How do you prevent VTE?

How can VTE be prevented? VTEs often are preventable, with strategies that stop the development of clots in people “at-risk.” Healthcare professionals discern risk by gathering information about a patient’s age, weight, medical history, medications and lifestyle factors.

Who gets VTE?

Approximately 1 in 20 people will have a VTE in their lifetime.

How is VTE treated?

Anticoagulants, or blood thinners, and thrombolytics are medicines commonly used to treat VTE. Anticoagulants, or blood thinners, keep blood clots from getting larger and stop new clots from forming. Conventional blood thinners include warfarin and heparin, but newer blood-thinning medicines are also available.

Who is most at risk for pulmonary embolism?

People at risk for PE are those who:

  • Have been inactive or immobile for long periods of time.
  • Have certain inherited conditions, such as blood clotting disorders or factor V Leiden.
  • Are having surgery or have broken a bone (the risk is higher weeks following a surgery or injury).


Does losing weight help with blood clots?

Regular exercise lowers your chances of getting a blood clot. Even walking can help. Take care of your health. That may mean losing weight or giving up smoking.

What is the most common cause of pulmonary embolism?

A pulmonary embolus is most often caused by a blood clot that develops in a vein outside the lungs. The most common blood clot is one in a deep vein of the thigh or in the pelvis (hip area). This type of clot is called a deep vein thrombosis (DVT).
