. Spider Veins

Spider Veins:–Spider veins can be blue, purple, or red and may appear in the form of thin lines, webs, or branches. People sometimes also refer to them as thread veins.

Spider veins are most common on the thighs, ankles, and calves, and are more common in women than men. Their cause isn’t completely understood in every case, but they can run in families. Some cases are related to pregnancy, use of birth control pills or weight gain. Other types of problematic veins that can appear similar to spider veins include:

Telangiectasias, which are dilated capillaries close to the skin, and tend to be more noticeable on the face, whereas spider veins more commonly occur on the legs and feet

Hemangiomas and angiomas, which are made up of very small arteries called arterioles or very small veins called venules.

Sometimes, the terms of spider veins and telangiectasias are used interchangeably.

Symptoms

Red or bluish-purple blood vessels appear, usually on the legs or thighs, but sometimes on the face, forearms or hands. Spider veins usually do not cause any symptoms, but rarely may cause mild dull discomfort or burning sensation.

Diagnosis

Your health care professional can diagnose spider veins by looking at them.

Expected Duration

Spider veins may be permanent or may disappear on their own after months, especially if they are caused by pregnancy or certain medications.

Prevention

Because the causes of spider veins aren’t completely understood, they can’t always be prevented. It’s helpful to maintain a healthy weight and stay physically fit. If you have spider veins, you might help to avoid developing more of them by not standing still or crossing your legs for prolonged periods and by wearing support stockings.
