What Is Vein Disease?
Venous disease starts when blood doesn’t flow properly through the veins back to the heart. The pooling of blood in the vein (venous reflux) causes it to swell, leading to discoloration and discomfort. Large visible veins are called varicose veins, while smaller veins are known as spider veins. Sometimes venous reflux can also occur in veins that are not visible on the surface.
Varicose veins and spider veins come in all shapes and sizes. They affect approximately 40% of adults. While many see varicose veins and spider veins as a cosmetic matter, varicose veins could actually lead to life-threatening health issues without proper treatment.
