A blood clot in a leg is called deep vein thrombosis (DVT).
Check if you're at risk of blood clots
Blood clots are rare in young, healthy people.
You're more likely to get them if you:
- are staying in or recently left hospital – especially if you can't move around much (like after an operation)
- are overweight
- are using combined hormonal contraception such as the combined pill, contraceptive patch or vaginal ring
- have had a blood clot before
There are also other things that increase your risk of clots.
How to prevent blood clots
If you're at a high risk of blood clots – for example, you're in hospital – follow the advice of your care team about preventing clots.
This may involve wearing stockings that improve your blood flow or taking medicine to reduce the risk of clots (anticoagulants).
There are also things you can do to help avoid clots.
