Jan. 16, 2010 -- (HealthDay News) -- Blood clots most often occur in people who don't move around enough and among people who have had recent surgery or injury. A clot can travel to the heart or brain, leading to a heart attack or stroke.
The U.S. Department of Health and Human Services suggests how to help prevent a blood clot:
Wear clothing and socks that fit loosely.
Occasionally lift your legs to about six inches above your heart.
If prescribed by your doctor, wear compression stockings.
Follow your doctor's recommendations for exercise and take all medications as prescribed.
Avoid sitting or standing in the same position for longer than one hour.
Limit your salt intake.
Avoid crossing or bumping your legs.
Don't put pillows beneath your knees.
Elevate the end of your bed about four to six inches.
