Varicose veins

Learn the risks and how to keep your legs healthy

Yes, they can be unsightly, and for the one in five Canadians who suffer from varicose veins, these dark blue, twisted, swollen vascular strands that occur in legs are responsible for considerable aching, heaviness, itchiness, fatigue, burning and pain. Varicose veins are often greater than 4 millimetres (one-eighth inch) in diameter, and may, in rare occasions, lead to dangerous blood clots.

Veins have one-way valves that direct blood that has all its oxygen used up back to the heart to be reoxygenated—hence the blue colour. When these valves become weak, blood pools and collects in the lower extremities, building up pressure and deforming the veins. Women are more susceptible to this, and the issue can run in families. Being overweight, being older or simply sitting or standing for long periods of time increases the risk of developing them, as do liver and heart diseases.

Compression stockings are recommended to help battle varicose veins. Knee-length socks are preferred over thigh-high options, because they target the most common areas affected. These stockings work by gradually tightening as they reach the feet, improving circulation and preventing blood from collecting in one place. Having compression stockings fitted by a certified individual may help achieve better results.

When varicose veins bleed or are red and warm to the touch, this may be a signal to see a doctor who can examine you for more invasive procedures. Most measures involve physically manipulating the affected area in some way. Burning and closing up the veins can be accomplished by lasers, radiofrequency ablation or injections of chemicals. The veins can also be cut or removed surgically.

Armed with this newfound knowledge, you can now better navigate the sometimes misunderstood world of these strange blue webs that cause more than cosmetic trouble.
