What are some causes for healthy 35 male to have blood clots in legs and lungs? non smoker, not over weight, no recent travel, and neg for factor v.

Possibilities: There are many possible diagnoses/causes for clotting abnormally. You need a full work up. Hope this link helps: http://my.Clevelandclinic.Org/heart/disorders/vascular/hypercoagstate.Aspx.

Hypercoagulable stat: Get checked for other hypercoagulable states like protien c & s, antiphospholipid antibody, prothrombin gene mutation, antithrombin3, homocysteine etc. Older pts we recommend to screen for cancers also.
