Varicose Veins are swollen and enlarged veins that usually occur on
the legs and feet. They may be blue or dark purple in colour, and are
often lumpy or twisted in appearance. They are caused by blood pooling
in the veins, causing them to bulge.

Varicose veins can cause pain, swelling and discomfort in the feet. A
feeling of aching/heaviness is common. Burning, throbbing, cramping or
swelling in the lower limbs is also reported. Pain is usually worse
after sitting or standing for a long period of time. Varicose veins
can increase the risk of blood clots and ulcerations.

Risk factors for developing varicose veins include:
1) age - wear and tear on the veins throughout life
2) sex - women are more likely, due to hormonal changes and/or
contraception pill
3) pregnancy - increased blood volume during pregnancy increases risk
of varicose veins
4) obesity - increased weight increases pressure to veins

Treatment options for varicose veins in the feet include compression
stockings, lifestyle changes and possibly a need for surgical
intervention.
