Compression stockings are used for a variety of benefits, including reduced swelling of your legs when sitting for an extended period of time, such as a long flight or car trip. Surgeons often use them during and after surgery to reduce your risk for developing a potentially life-threatening blood clot. Runners sometimes use them to increase blood flow during exercise, which some think may reduce soreness, although the research is not conclusive on this stance.
Purpose of Compression
The compression of the stockings is used to mimic the pumping action of your muscles as you walk. Normally, when you walk, your muscles contract around and near the veins in your legs, helping to force the blood upward against gravity and back toward your heart. However, if you have edema, lymphedema, poor circulation or varicose veins, just to name a few conditions, your body isn't able to effectively push the fluid up out of your legs, causing chronic swelling and pain.
Compression stockings effectively push fluid upward by using graduated compression. There are several different types of stockings, from "diabetic socks" to knee high stockings and hip height stockings. Your doctor or therapist will determine the most appropriate height as well as tightness of the compression to meet your physical needs. Your compression stockings work from the foot up, tighter at the foot, with the compression easing higher up the leg.
