There are many benefits of using compression leggings for venous insufficiency and other venous diseases, including varicose veins.  

Chronic venous insufficiency (CVI) happens when the vein walls and valves in your legs do not work well enough to return blood to your heart. To get blood from your legs to your heart, muscle contraction in your legs squeeze the veins and push the blood up. The valves in your veins let the blood flow upward, but prevent it from running back down.

Weak vein walls and valves interrupt this normal upward flow of blood. CVI can be caused by venous leg ulcers, blood clots and even for unknown reasons. The pooling of blood can cause swelling in the legs, tightness and/or pain in the legs, especially when walking, and varicose veins. 

3 Ways Compression Leggings Help CVI

Compression leggings can help relieve many of the symptoms of CVI and varicose veins. One of the great advantages of compression wear as a treatment for venous symptoms is that they can be worn comfortably all day.

1. Better Blood Circulation - The gentle pressure that compression stockings apply along the entire length of your leg can help support leg muscles and veins. The added support helps the vein walls and valves do their job and reduces the workload they face to move blood back to the heart.
   
   
2. Less Swelling - Compression also makes it more difficult for blood to pool in your legs, which, in turn, makes it easier for your circulatory system to pump it out of your legs.
   
   
3. Improves Lymph Flow & Removes Lactic Acid - Compression wear promotes the flow of lymph fluid through your legs to remove many impurities in your blood, and helps remove lactic acid from your leg muscles. Both of these can help to reduce symptoms of pain and discomfort.
