1 in 3 people will have long-term complications following a DVT(1).




1 in 4 people’s first symptom of a PE is sudden death(1)



DVT and PE are part of a condition called venous thromboembolism (VTE).

VTE is the third-most common cardiovascular disease affecting 10 million people globally(2)

        VTE is estimated to cost $1.7 billion in Australia per year(3)



If you experience these symptoms you should seek medical advice immediately.


For an in-depth review of information about DVT and PE, follow the links below:




What are the chances of developing another thrombosis (deep vein thrombosis or DVT)?

The risk of having a DVT is higher for someone who has already had one. However, this risk is different for everyone – depending on your medical history, family history, and more.

Will my swelling go away?

The swelling may remain for some time. Compression stockings can help to increase blood flow and reduce swelling, as well as help to prevent any complications from the DVT.

What are the warning signs of a DVT or pulmonary embolism (PE)?

See above.

What should I expect after a PE?

After a PE it is common to experience shortness of breath as well as mild pain or pressure – especially during exercise or deep breathing. These symptoms will improve over time, and mild exercise can help you to recover more quickly.

Who should I tell that I am taking blood thinners?

Your doctors, nurses, dentist, or other healthcare practitioners.

Who should I tell that I have had a blood clot?

Any doctor or healthcare professional that is caring for you, including if you are hospitalised for any reason.

Is it okay to exercise after a blood clot?

You must talk to your doctor about whether and how much you should exercise. Mild exercise such as walking and swimming can be beneficial to increasing circulation and reducing swelling.

What can I do to minimise my risk of a first-time or recurrent DVT?

Staying active and maintaining a healthy weight, staying hydrated, eating a healthy diet, avoiding immobility, and avoiding stress can all help to reduce the risk of a DVT.  

What are anticoagulants?

They are medicines in the form of tablets or injections that are given to significantly reduce the risk of blood clots.

What are the risks associated with anticoagulants?

Excessive bleeding or internal haemorrhage are more likely when taking an anticoagulant. Ask your doctor about any modifications to your lifestyle or other medicines before starting anticoagulants.  If you are on anticoagulants tell your doctor if there are any signs of bleeding, or your health professional before changing to other medication, or prior to surgical procedures.
