Had 2nd dvt pe from surgery & t therapy have lupus anticoagulant on lifetime xarelto once clots resolve, can i safely resume scuba diving?

Yes: No problems resuming your normal activities. In fact, the more the better. DVT's and pulmonary embolism are less likely if you remain active. Sitting around, with restricted blood flow is the problem. If you are a hypercoagulator, check your levels of fibrinogen. If elevated, take high-dose turmeric (fibrinogen is the last factor in the clotting cascade--Turmeric brings levels down)

Possibly but : you need to discuss this with your physician, your cardiologist, and your pulmonary specialist. Keeping the blood thinners is one thing, the question is, are there any other medical issues that might be responsive to scuba diving
