What are Vein Disorders?

Veins are the blood vessels that transport blood back to the heart.  There are several types of vein disorders.  The most common of which are Varicose veins, Spider veins and Deep vein thrombosis.
 
The major components of the vein wall are smooth muscle, collagen and elastin.  A vein disorder refers to a condition in which part of the vein wall is damaged and in wrong proportions.

Varicose Veins

Varicose veins are very swollen and raised above the surface of the skin. They are dark purple or blue in color. They are found most often on the backs of the calves or on the inside of the leg, anywhere from the groin to the ankle.  The veins in the legs carry the greatest burden by fighting gravity and carring blood back up to the heart.  If you are overweight then you are at a higher risk of developing varicose veins.

Varicose veins are a condition that can occur when the vein experiences more pressure then it can handle, resulting the inability to push all of the blood back up to the heart.  As a result the blood can actually flow backwards causing the blood to pool which results in the vein growing even wider.  Usually, there are no symptoms except for the veins being very large and noticeable. 

Spider Veins

Many people with varicose veins also have spider veins, which are, despite the name, enlarged capillaries, not veins. Capillaries are tiny blood vessels that connect the arteries and veins. Just like varicose veins, spider veins  also appear purple in color.
 
Deep Vein Thrombosis

This is a blood clot in the vein and is most often found in the calf muscle or the veins in the leg.  This condition is fairly common and can be attributed to inactivity.  When a person is inactive, the leg muscles do not contract and squeeze blood vessels forcefully enough to propel blood to the heart. Blood then pools in the leg veins, where it can clot easily.  Occasionally, one or more of these clots then can break loose and travel back up to the heart.  This can lead to a number of other complications.  If you are experiencing any pain, redness or swelling in the calves or thigh - then pay a special visit to your primary care physician for additional testing.
