The claim: “Eating lunch at your desk could increase your risk of DVT”—was the dramatic headline from UK’s Marie Claire magazine which caught my attention. (1) The online story went on to say that “Almost 75 per cent of office staff aged 21-30 who work 10-hour days don’t get up to take a break. This could double chances of a fatal blood clot.” The story was light on citing scientific evidence to back up this claim, so, as someone interested in DVT education (and admittedly, who eats at her desk routinely), I decided to investigate if this assertion is true: Does eating lunch at your desk increase blood clot risk?
The answer: Yes. The act of eating lunch at your desk, in and of itself, does not increase blood clot risk; but the immobility associated with prolonged sitting at your desk, does.
