What Are the Causes of Spider Veins in Women?

Spider veins are enlarged veins close to the skin's surface that branch out or resemble red and blue spider webs. WomensHealth notes that spider veins can be found on the face, pelvis legs and cover small or large areas. Spider veins are the visible result of problems with the blood veins and are visible on men; however women are especially prone to this condition.

Vascular Damage

• Spider veins are a smaller version of varicose veins that are abnormal, dilated blood vessels caused by weakening in the wall of blood vessels, according to the Cleveland Clinic. The spider veins can exist alone or branch off from larger, often twisted or bulging varicose veins. Not only is the appearance of varicose or spider veins unsightly, the condition can cause itching, swelling and aches. Legs may feel tired with throbbing or tingling sensations. Although spider veins are common and may be uncomfortable, they are not a serious medical condition.

Medical History

• A family history of varicose or spider veins increases the odds of developing varicose and spider veins by 50 percent. Medical conditions that increase pressure on veins or abdomen could lead to vascular damage. The Cleveland Clinic notes liver disease, fluid in the abdomen, previous groin surgery or heart failure are some conditions that could cause varicose or spider veins. Trauma or injury to the skin, including previous surgeries on the veins or the use of topical steroids could be also be developing factors. Excessive exposure to the sun's ultraviolet rays may cause areas of sun-damaged skin to develop spider veins---including the face.

Hormonal Changes

• Women experience a number of major hormonal changes from puberty to menopause, in addition to monthly fluctuations in hormone levels. Birth control pills contain hormones that can cause a number of side effects including vascular damage. Pregnancy not only comes with dramatic hormonal changes, but also increases the amount of blood in the woman's body according to WomensHealth. Pregnancy also increases abdominal pressure for a prolonged period.

Age and Activity

• The older a woman gets, the greater the chances she develops spider veins. Aging is not simply the passage of time, it is the pathological deterioration of body tissues, including the vascular system. Poor lifestyle choices speed up the aging process in young women that leads to health problems and unsightly spider veins. Obesity is not only the result of bad choices, but the extra body fat increases abdominal pressure and causes the body to produce more blood. Obesity also decreases activity which is a cause of spider veins. Women who stand for long periods of time, such as cashiers and waitresses are at risk, as gravity pulls the blood downward, but there is not sufficient movement for proper circulation.

Prevention and Care

• Regardless of a woman's genetic or medical history, she has of control over spider veins. Not smoking along with healthy eating, regular activity and avoiding sun exposure improve the skins overall appearance and helps prevent spider veins. Don't wear clothing too tight around the waist that prevents good circulation. For the woman who already has spider veins, WomensHealth notes that medical attention improves the skin's appearance, relieves symptoms and prevents further complications.
