A compression hose is a snug-fitting medical garment that applies graduated pressure to the legs, improving blood flow and preventing fluid buildup in venous and lymphatic conditions.
Compression hose—clinically interchangeable with compression stockings or socks—are elastic medical garments designed to apply controlled pressure from the ankle upward, with the highest pressure at the ankle. This graduated squeeze helps push blood back toward the heart, reduces leg swelling, and supports valve function in veins. Whether you’re managing varicose veins, recovering from surgery, or spending long hours on your feet, understanding what compression hose are and how they work is the first step to using them effectively.
How Compression Hose Work
Compression hose exert graduated pressure—tightest at the ankle, gradually decreasing up the leg. This gradient mechanically squeezes distended veins, reducing their diameter and increasing blood flow velocity. The result is better venous return and improved valve function, which prevents blood from pooling in the lower legs.
This mechanism treats and prevents conditions like varicose veins, spider veins, deep vein thrombosis (DVT), and lymphedema. For bedridden patients, anti-embolism stockings provide more uniform pressure to prevent DVT, though standard graduated compression hose are the primary tool for most venous and lymphatic conditions.
Materials are typically elastic blends of nylon, spandex, and rubber. Design variations include closed-toe, open-toe, knee-high, thigh-high, and pant styles—each chosen based on the condition and where swelling or vein issues occur.
Compression Levels and What They Mean
Compression is measured in millimeters of mercury (mmHg), with levels matched to specific medical needs. The higher the number, the stronger the squeeze.
For a detailed comparison of top-rated products at different compression levels, our roundup of the best compression hose breaks down options for each use case.
8–15 mmHg (light) is used for non-specific leg fatigue and minor swelling. 15–20 mmHg (mild) works for minor varicose veins, travel, and daily wear to prevent mild edema. 20–30 mmHg (moderate) targets moderate swelling, superficial vein clots, post-thrombotic syndrome, and orthostatic hypotension—often requiring a prescription. 30–40 mmHg (high) is for severe varicose veins, lymphedema, and venous ulcers, requiring medical supervision. Levels above 40 mmHg are reserved for severe venous insufficiency and critical lymphatic conditions.
Over-the-counter compression hose are available in 8–20 mmHg at medical supply stores and online. Levels of 20–30 mmHg and above generally require a doctor’s prescription. Incorrectly sized hose can cause pain, numbness, or skin ulcers, so proper fitting is essential.
Who Needs Compression Hose?
Compression hose are prescribed for a range of venous and lymphatic conditions: varicose and spider veins, DVT prevention and post-thrombotic syndrome, chronic venous insufficiency (including venous eczema and lipodermatosclerosis), lymphedema, edema during pregnancy, orthostatic hypotension, and post-surgical recovery. The controlled pressure prevents blood and fluid pooling, assisting the natural skeletal-muscle pump.
However, compression is not recommended for patients with severe peripheral arterial disease unless specifically prescribed by a doctor. Always consult a healthcare provider before using compression hose above 20 mmHg.
Getting the Right Fit
Proper fit is critical. Measure ankle circumference at the narrowest point just above the ankle bone, calf circumference at the widest part, and height from the flat of the foot to the bend of the knee (for knee-high) or to the top of the thigh (for thigh-high). Use the sizing chart for the specific pressure level. Put the hose on first thing in the morning before swelling starts. Ensure the band lies flat without rolling, and the top sits about two finger-widths below the crease of the knee.
Common mistakes include incorrect sizing, pulling the top into the knee crease, and confusing compression levels. A poorly fitted hose may cut off circulation or cause discomfort. If you experience numbness, pain, or skin changes, remove the garment and consult a professional.
FAQs
Can I wear compression hose overnight?
Standard graduated compression hose are designed for daytime wear when you’re upright and swelling occurs. Wearing them overnight is generally not recommended unless a doctor specifically prescribes bedtime use, usually with flat-knit anti-embolism stockings for bedridden patients.
How long do compression hose last?
Most compression hose maintain their pressure for about 4 to 6 months with regular wear and proper care. Hand-wash them in mild soap and air-dry away from direct heat to extend their life. Replace them when they start to lose elasticity or if you notice decreased symptom relief.
Do I need a prescription for compression hose?
Over-the-counter levels (8–20 mmHg) are available without a prescription. Compression levels of 20–30 mmHg and higher generally require a doctor’s prescription because improper use can cause harm, especially in patients with undiagnosed arterial disease. Always consult a healthcare provider for levels above 20 mmHg.
