Deep vein thrombosis, or DVT, is a blood clot in a vein deep in your body. DVT is treatable but can be very dangerous and lead to life-threatening or fatal events, like a stroke or heart attack, if left unchecked.

Some medical conditions, habits, and events can raise your risk of blood clots. For example, did you know that women taking birth control pills are at greater risk, or that your risk is higher if you just had surgery?

It’s important to understand the factors that make blood clots more likely and to make healthy choices — like losing weight or quitting smoking — to help keep your risks low.

Learn about the signs and symptoms of DVT, how you can identify your risks, the most common treatments and procedures available, and when to talk to your doctor.
