Varicose
veins are large, raised, swollen blood vessels
that twist and turn. They usually develop in the legs and can be seen through
the skin.
Spider veins are smaller, red,
purple, and blue vessels that also twist and turn. Spider veins are easily
visible through the skin, as well. They are typically visible on the legs and
face.
Causes of Varicose Veins and Spider Veins
A number of factors predispose a person to varicose
veins and spider veins. These include:
·
Heredity
- Occupations that involve a lot of standing, such as nurses, hair stylists, teachers, and factory workers
- Obesity
- Hormonal influences of pregnancy, puberty, and menopause
- The use of birth control pills
- Postmenopausal hormonal replacement
- A history of blood clots
- Conditions that cause increased pressure in the abdomen, such as tumors, constipation, and externally worn garments like girdles.
Other reported causes include trauma or injury to the skin,
previous vein surgery, and exposure to ultraviolet rays.
Other Risk Factors for Varicose Veins and Spider Veins
Varicose veins and spider veins develop more often in women than
in men. They increase in frequency with age. An estimated 30% to 60% of adults
have varicose veins or spider veins.
Symptoms of Varicose Veins and Spider Veins
Many people with varicose veins complain of pain, described as an
aching or cramping in the legs. Other common symptoms include tiredness,
restlessness, burning, throbbing, tingling, or heaviness in the legs. Pain from
these veins is usually relieved by elevating the legs or by wearing support
hose.
In women, symptoms may be worse during certain parts of the menstrual
cycle or during pregnancy. Less common is swelling, ulcers and a darkening of
the skin, especially in the ankle
region. Occasionally, varicose veins can form a painful blood clot with
inflammation of the vein, a condition called thrombophlebitis.
