Deep vein thrombosis (DVT) is a condition where one or more blood clots form within the large veins in your legs. Clots can have symptoms of their own and can become fatal if they travel to your lungs where they develop into pulmonary embolisms. 

Everyone is at risk of developing DVT, but certain activities can expose athletes to more risk than others in their age group. Read on to learn ten things that put athletes at risk for DVT. 

1. Higher Risk of Leg Injury

Some sports, particularly ones like basketball and hockey, have higher rates of leg injuries. 

Any damage to your leg can increase your chance of developing DVT. 

The greater the damage, the greater the risk. The worst is a break that requires a cast and the most minor is something like being hit with a hockey puck. 

2. Higher Risk of Injuries that Need Surgery
