Varicose veins: Here's what you can do about them
Varicose veins is a term commonly used to describe visible leg veins. But true varicose veins are dilated and very
prominent. Small varicose veins may not be a problem, but as varicose veins worsen they become distended and
tortuous (full of twists and turns) and can cause the legs to feel heavy and ache.
Swelling of the feet and ankles is an early sign of impaired function of the valves in our veins that keep the blood
flowing, and severe varicose veins can be very painful.
There's good evidence varicose veins have a genetic link and are also associated with a history of deep vein thrombosis
(blood clots that obstruct the veins).
It's not possible to prevent varicose veins from forming, but simple actions can improve blood circulation in the feet and
legs, and stop varicose veins from getting worse.
Try to elevate your legs when sitting, resting and sleeping; reduce weight if you are overweight or obese; and wear
lower-heeled shoes to work calf muscles.
Treatments for varicose veins depend on the severity of symptoms, aesthetics and the risk of complications. Treatment
may include compression stockings, lifestyle changes or a range of surgical options.
