Maintain a healthy lifestyle, stop smoking, exercise regularly, and prevent obesity. In situations of high DVT risks such as major surgery, do discuss with your doctor on preventive measures which include medications such as blood thinners and physical methods such as foot/calf pumps and compression stockings.

If the occurrence of DVT or PE is suspected it is best to seek medical help and to confirm the presence of DVT with radiological imaging such as a duplex ultrasound of the affected leg.
