On this page we explain what you can do to avoid getting a pulmonary embolism.

How to prevent blood clots

We can all reduce our risk of blood clotting by changing our habits to lead a healthier lifestyle:

• stopping smoking - if you smoke, quitting is the best thing you can do for your health
• getting regular exercise
• not sitting still for a long time – such as when watching TV or using a computer
• avoid becoming dehydrated
• maintaining a healthy weight, by eating a healthy balanced diet

How to prevent deep vein thrombosis (DVT)

As pulmonary embolism is often caused by deep vein thrombosis (DVT), it’s important to take steps to prevent DVT.

If you're being treated in hospital for another condition, your medical team will take steps to prevent you getting DVT. After surgery, you should move around or do leg exercises as soon as this is safe.

There are things you can do to prevent a travel-related DVT on long-haul journeys:

• wear loose, comfortable clothes
• do leg stretching exercises: bend and straighten your legs, feet and toes every 30 minutes when you’re sitting
• walk around whenever you can
• wear flight socks
• avoid dehydration

If you’re at risk of developing blood clots, consult your health care professional before travelling long distances. The NHS has a useful webpage on how to prevent DVT when you travel.

Should I wear compression stockings?

Compression stockings fit tightly round your lower legs and encourage your blood to flow more quickly around your body. You should wear them only if they are prescribed to you by a health care professional.
