Obesity and venous thrombosis: a review

Allman-Farinelli, Margaret·2011·Seminars in Thrombosis and Hemostasis

Abstract

The world is experiencing an obesity pandemic, with rates of obesity rising for more than two decades. Obesity is defined as a body mass index (BMI) of 30 kg/m (2) or greater. Of particular concern are the risks that millions of obese people are likely to develop chronic diseases and at earlier ages than their parents might have. The risk of venous thrombosis increases with obesity, so that the incidence of this pathology is also expected to rise significantly. There is remarkable and consistent evidence from a systematic review, as well as cohort and case-control studies that obesity might predispose to venous thromboembolism (VTE). The risk appears to be at least double that for normal weight subjects (BMI 20 to 24.9 kg/m (2)). Plausible mechanisms exist to explain this relationship, including the physical effects of body fat limiting venous return and a proinflammatory, prothrombotic, and hypofibrinolytic milieu. Loss of body weight has been shown to reduce the concentrations of coagulation factors and plasminogen activator inhibitor-1 toward the normal range. Whether weight loss would prevent secondary occurrence of VTE in the absence of anticoagulant therapy could not be discerned from this literature search.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
