Mmhg stands for millimeter of mercury, a unit of measuring pressure. When it comes to compression stockings, mmHg refers to how tightly the elastic medical stockings support the veins in the leg. The higher the mmHg number, the greater the graduated stocking will squeeze the patient’s leg.
mmHg stockings come in a variety of brands (such as Sigvaris, Mediven, Jobst, and Juzo), styles, and compression levels. Here is a list of compression levels and who they’re used for:
Doctors typically recommend these stockings for people with aching, fatigued legs; pregnant women; or people with careers that have them on their feet a lot. You can buy 8 to 15 mmHg stockings over the counter.
This therapeutic version of stockings is often useful for people whose legs are prone to fatigue and swelling. Pregnant women, people with spider or varicose veins, or people with inherited circulatory problems may need to wear 15-20 mmHg stockings.
Patients with a lot of heaviness and swelling in the legs, mild varicose veins, varicose veins during pregnancy, or who’ve just undergone vein surgery wear 20 to 30 mmHg stockings.
Who wears 30-40 mmHg stockings? Patients prone to blood clots (such as deep vein thrombosis), post-surgery patients, pregnant women with phlebitis, people with severe leg swelling and scars, stasis dermatitis sufferers, and those with lymphedema.
People with severe venous ulcers, severe circulatory problems, and lymphedema need to wear these medical grade 40 50 mmHg compression levels.
People with severe lymphedema, who’ve undergone surgery for compression lymphedema, and severe post thrombotic syndrome need to wear 50 60 mmHg ones.
Your doctor will help you decide which compression level is best for you and your medical condition.
