Can a dvt go away on its own? without medication

Yes....: Most medications to treat blood clots work by keeping the clots from getting bigger while your own body dissolves the clot. So, if a clot is not increasing in size, your body's natural system will slowly dissolve the clot.

Yes it can: Each individual is different and depends on how extensive the clot is. With small clots the body has a better chance of dissolving it on its own. With larger symptomatic clots this is less likely and you would probably need some form of anticoagulation therapy for at least 3-6 months.

Superficial or deep.: Smaller superficial vein thrombosis can dissolve spontaneously and can be helped along with just warm soaks to the calf. Deep vein thrombosis tends not to go away without medications, and if left alone could fractionate and parts can travel to the lungs, causing a potentially dire situation called pulmonary embolism.

Dvt: Deep vein thrombosis is being treated with blood thinners to prevent possible pulmonary embolism. None of these medications will dissolve the clot and clot will usually resolve over a period of time.

RX DVT: DVT almost always requires medication to improve and resolve. Anticoagulation does not dissolve the clot but it does help to prevent the clot from extending and also helps to reduce the risk of pulmonary embolisms by thinning the blood. DVT from the mid calf up requires blood thinners Select cases of DVT in the lower calf can be treated by ASA alone.It is best to err on the side of safety in Rx.
