Currently, it is estimated that 25,000 people who are admitted to hospital die from preventable venous thromboembolism (blood clots in the leg and potentially fatal clots which travel to the lung) each year. This has led the Department of Health to make the prevention of this “silent killer” across the NHS a priority for the forthcoming years.
You can help prevent blood clots if you:
- Wear loose-fitting clothes, socks, or stockings.
- Raise your legs 6 inches above your heart from time to time.
- Wear special stockings (called compression stockings) if your doctor prescribes them.
- Do exercises your doctor gives you.
