What Is Deep Vein Thrombosis?
Deep vein thrombosis (DVT) is a serious condition that occurs when a blood clot forms in a vein located deep inside your body. A blood clot is a clump of blood that is in a gelatinous, solid state. Deep vein blood clots typically form in your thigh or lower leg, but they can also develop in other areas of your body.
Who Is At Risk for Deep Vein Thrombosis?
DVT occurs most commonly in people who are over 50 years in age. Certain conditions that alter how your blood moves through your veins can raise your risk of developing clots. These conditions include:
- injury that damages your veins
- excess weight, which puts more pressure on the veins in your legs and pelvis
- family history of DVT (hereditary blood clotting disorders)
- taking birth control pills
- undergoing hormone therapy
- smoking (especially heavy usage)
- staying seated for a long time while you’re in a car or on a plane, especially if you already have at least one other risk factor
- having a catheter placed in a vein
- inflammatory bowel disease
