If you like to play video games listen up! A recent case study published in the Journal of Medical Case Reports found that one man who played video games for eight hours a day four days straight developed deep vein thrombosis and had many blood clots in his legs.
The unidentified patient, who played while in bed, went to a doctor when he had swelling and pain in his legs.
Deep vein thrombosis usually occurs when a person is immobile or still for long periods of time and can lead to a life-threatening pulmonary embolism if the clots travel to the lungs. Common symptoms for deep vein thrombosis include swelling of the leg, pain in the lower or upper extremities or feeling like one shoe is too tight.
If a patient with a pulmonary embolism is not treated, the condition is fatal nearly 30 percent of the time according to the National Institutes of Health.
In 2011, a British man died from a pulmonary embolism after playing video games up to 12 hours per day.
Cardiologists say cases where a person appears to suddenly develop blood clots on a long-distance flight or other common activity such as playing video games, it often indicates that the person had secondary risk factors.
Microsoft, the makers of Xbox, say they recommend gamers take breaks to exercise as well as "make time for other pursuits."
